For our test PHP file, we added a simple function that returns a number to be displayed along with a message. By comparison, after this was run through the encoder the downloaded file contained the following:. The important question now is: will the installed ionCube decoder extension be able to analyze the file and decode it so that it can be executed as normal PHP code?
To find out, we uploaded both PHP files to the server and viewed them in the browser. First up is the original file containing the raw PHP code. This displays exactly the same so the ionCube decoder extension is verified as installed and working correctly. One final thing you can do to verify installation has been successful is to view the server error logs and look for recent entries relating to the ionCube installation. Kinsta customers can view error logs in their MyKinsta dashboard. To do this, the loader needs to be installed correctly via a series of terminal commands when connected to the server using an SSH connection.
Once you establish a secure connection to your server, you can begin the ionCube loader extension installation process which can be broken down into a series of steps:.
If anything goes wrong during the installation process, or just for peace of mind, you can also check the server logs for any errors that may have occurred. All of that and much more, in one plan with no long-term contracts, assisted migrations, and a day-money-back-guarantee.

However, I prefer to get back to the basics and always strive to somehow find a direct URL to the PDF file to then download it via curl or wget.
At the same time, it also stores the HTTP cookie s set by the web server when accessing named web page. These cookies are then re-used when accessing the PDF file directly. This has reproducibly worked for me. If the supplied file does not exist, Wget will create one. This file will contain the new HSTS entries. If no HSTS entries were generated no Strict-Transport-Security headers were sent by any of the servers then no file will be created, not even an empty one.
Care is taken not to override possible changes made by other Wget processes at the same time over the HSTS database.
For more information about the potential security threats arose from such practice, see section 14 "Security Considerations" of RFC , specially section Specify the username user and password password on an FTP server. To prevent the passwords from being seen, store them in.
Normally, these files contain the raw directory listings received from FTP servers. Not removing them can be useful for debugging purposes, or when you want to be able to easily check on the contents of remote server directories e. Note that even though Wget writes to a known filename for this file, this is not a security hole in the scenario of a user making.
Depending on the options used, either Wget will refuse to write to. A user could do something as simple as linking index. Turn off FTP globbing. By default, globbing will be turned on if the URL contains a globbing character. This option may be used to turn globbing on or off permanently. You may have to quote the URL to protect it from being expanded by your shell. Globbing makes Wget look for a directory listing, which is system-specific. Disable the use of the passive FTP transfer mode. Passive FTP mandates that the client connect to the server to establish the data connection rather than the other way around.
If the machine is connected to the Internet directly, both passive and active FTP should work equally well. By default, when retrieving FTP directories recursively and a symbolic link is encountered, the symbolic link is traversed and the pointed-to files are retrieved.
Currently, Wget does not traverse symbolic links to directories to download them recursively, though this feature may be added in the future.
Instead, a matching symbolic link is created on the local filesystem. The pointed-to file will not be retrieved unless this recursive retrieval would have encountered it separately and downloaded it anyway.
This option poses a security risk where a malicious FTP Server may cause Wget to write to files outside of the intended directories through a specially crafted. Note that when retrieving a file not a directory because it was specified on the command-line, rather than because it was recursed to, this option has no effect.
Symbolic links are always traversed in this case. All the data connections will be in plain text. For security reasons, this option is not asserted by default. The default behaviour is to exit with an error. Turn on recursive retrieving. See Recursive Download , for more details. The default maximum depth is 5. Set the maximum number of subdirectories that Wget will recurse into to depth.
In order to prevent one from accidentally downloading very large websites when using recursion this is limited to a depth of 5 by default, i. Ideally, one would expect this to download just 1. This option tells Wget to delete every single file it downloads, after having done so. It is useful for pre-fetching popular pages through a proxy, e. After the download is complete, convert the links in the document to make them suitable for local viewing. This affects not only the visible hyperlinks, but any part of the document that links to external content, such as embedded images, links to style sheets, hyperlinks to non- HTML content, etc.
This kind of transformation works reliably for arbitrary combinations of directories. Because of this, local browsing works reliably: if a linked file was downloaded, the link will refer to its local name; if it was not downloaded, the link will refer to its full Internet address rather than presenting a broken link.
The fact that the former links are converted to relative links ensures that you can move the downloaded hierarchy to another directory. Note that only at the end of the download can Wget know which links have been downloaded. This filename part is sometimes referred to as the "basename", although we avoid that term here in order not to cause confusion. It proves useful to populate Internet caches with files downloaded from different hosts. Note that only the filename part has been modified. Turn on options suitable for mirroring.
This option turns on recursion and time-stamping, sets infinite recursion depth and keeps FTP directory listings. This option causes Wget to download all the files that are necessary to properly display a given HTML page. This includes such things as inlined images, sounds, and referenced stylesheets.
Ordinarily, when downloading a single HTML page, any requisite documents that may be needed to display it properly are not downloaded. For instance, say document 1. Say that 2. Say this continues up to some arbitrarily high number. As you can see, 3. However, with this command:. One might think that:.
Links from that page to external documents will not be followed. Turn on strict parsing of HTML comments. Until version 1. Beginning with version 1. Specify comma-separated lists of file name suffixes or patterns to accept or reject see Types of Files.
Specify the regular expression type. Set domains to be followed. Specify the domains that are not to be followed see Spanning Hosts. Without this option, Wget will ignore all the FTP links. If a user wants only a subset of those tags to be considered, however, he or she should be specify such tags in a comma-separated list with this option.
To skip certain HTML tags when recursively looking for documents to download, specify them in a comma-separated list. In the past, this option was the best bet for downloading a single page and its requisites, using a command-line like:. Ignore case when matching files and directories. The quotes in the example are to prevent the shell from expanding the pattern. Enable spanning across hosts when doing recursive retrieving see Spanning Hosts. Follow relative links only. Useful for retrieving a specific home page without any distractions, not even those from the same hosts see Relative Links.
Specify a comma-separated list of directories you wish to follow when downloading see Directory-Based Limits. Elements of list may contain wildcards. Specify a comma-separated list of directories you wish to exclude from download see Directory-Based Limits. Do not ever ascend to the parent directory when retrieving recursively. This is a useful option, since it guarantees that only the files below a certain hierarchy will be downloaded.
See Directory-Based Limits , for more details. With the exceptions of 0 and 1, the lower-numbered exit codes take precedence over higher-numbered ones, when multiple types of errors are encountered.
Recursive downloads would virtually always return 0 success , regardless of any issues encountered, and non-recursive fetches only returned the status corresponding to the most recently-attempted download. We refer to this as to recursive retrieval , or recursion. This means that Wget first downloads the requested document, then the documents linked from that document, then the documents linked by them, and so on.
In other words, Wget first downloads the documents at depth 1, then those at depth 2, and so on until the specified maximum depth. The default maximum depth is five layers.
When retrieving an FTP URL recursively, Wget will retrieve all the data from the given directory tree including the subdirectories up to the specified depth on the remote server, creating its mirror image locally.
FTP retrieval is also limited by the depth parameter. By default, Wget will create a local directory tree, corresponding to the one found on the remote server. Recursive retrieving can find a number of applications, the most important of which is mirroring.
It is also useful for WWW presentations, and any other opportunities where slow network connections should be bypassed by storing the files locally. You should be warned that recursive downloads can overload the remote servers.
Because of that, many administrators frown upon them and may ban access from your site if they detect very fast downloads of big amounts of content. The download will take a while longer, but the server administrator will not be alarmed by your rudeness. Of course, recursive download may cause problems on your machine. If left to run unchecked, it can easily fill up the disk. If downloading from local network, it can also take bandwidth on the system, as well as consume memory and CPU.
Try to specify the criteria that match the kind of download you are trying to achieve. See Following Links , for more information about this. When retrieving recursively, one does not wish to retrieve loads of unnecessary data. Most of the time the users bear in mind exactly what they want to download, and want Wget to follow only specific links. This is a reasonable default; without it, every retrieval would have the potential to turn your Wget into a small version of google.
However, visiting different hosts, or host spanning, is sometimes a useful option. Maybe the images are served from a different server. Maybe the server has two equivalent names, and the HTML pages refer to both interchangeably.
Unless sufficient recursion-limiting criteria are applied depth, these foreign hosts will typically link to yet more hosts, and so on until Wget ends up sucking up much more data than you have intended.
You can specify more than one address by separating them with a comma, e. When downloading material from the web, you will often want to restrict the retrieval to only certain file types. For example, if you are interested in downloading GIF s, you will not be overjoyed to get loads of PostScript documents, and vice versa. Wget offers two options to deal with this problem. Each option description lists a short name, a long name, and the equivalent command in. A matching pattern contains shell-like wildcards, e.
Look up the manual of your shell for a description of how pattern matching works. So, if you want to download a whole page except for the cumbersome MPEG s and.
The quotes are to prevent expansion by the shell. This behavior may not be desirable for all users, and may be changed for future versions of Wget.
It is expected that a future version of Wget will provide an option to allow matching against query strings. This behavior, too, is considered less-than-desirable, and may change in a future version of Wget.
Regardless of other link-following facilities, it is often useful to place the restriction of what files to retrieve based on the directories those files are placed in.
There can be many reasons for this—the home pages may be organized in a reasonable directory structure; or some directories may contain useless information, e. Wget offers three different options to deal with this requirement. Any other directories will simply be ignored. The directories are absolute paths. The simplest, and often very useful way of limiting directories is disallowing retrieval of the links that refer to the hierarchy above than the beginning directory, i.
Using it guarantees that you will never leave the existing hierarchy. Supposing you issue Wget with:. Only the archive you are interested in will be downloaded. Relative links are here defined those that do not refer to the web server root.
For example, these links are relative:. The rules for FTP are somewhat specific, as it is necessary for them to be.
FTP links in HTML documents are often included for purposes of reference, and it is often inconvenient to download them by default. Also note that followed links to FTP directories will not be retrieved recursively further. One of the most important aspects of mirroring information from the Internet is updating your archives. Downloading the whole archive again and again, just to replace a few changed files is expensive, both in terms of wasted bandwidth and money, and the time to do the update.
This is why all the mirroring tools offer the option of incremental updating. Such an updating mechanism means that the remote server is scanned in search of new files. Only those new files will be downloaded in the place of the old ones. To implement this, the program needs to be aware of the time of last modification of both local and remote files. We call this information the time-stamp of a file.
With this option, for each file it intends to download, Wget will check whether a local file of the same name exists. If it does, and the remote file is not newer, Wget will not download it. If the local file does not exist, or the sizes of the files do not match, Wget will download the remote file no matter what the time-stamps say. The usage of time-stamping is simple. Say you would like to download a file so that it keeps its date of modification.
A simple ls -l shows that the time stamp on the local file equals the state of the Last-Modified header, as returned by the server. Several days later, you would like Wget to check if the remote file has changed, and download it if it has. Wget will ask the server for the last-modified date.
If the local file has the same timestamp as the server, or a newer one, the remote file will not be re-fetched. However, if the remote file is more recent, Wget will proceed to fetch it. After download, a local directory listing will show that the timestamps match those on the remote server.
If you wished to mirror the GNU archive every week, you would use a command like the following, weekly:. Note that time-stamping will only work for files for which the server gives a timestamp. If you wish to retrieve the file foo.
If the file does exist locally, Wget will first check its local time-stamp similar to the way ls -l checks it , and then send a HEAD request to the remote server, demanding the information on the remote file.
If the remote file is newer, it will be downloaded; if it is older, Wget will give up. It will try to analyze the listing, treating it like Unix ls -l output, extracting the time-stamps.
