If you are looking for an algorithm that will allow you to download force download a big file, may this one will help you. File Transfer' ; header 'Content-Type: Using pieces of the forced download script, adding in MySQL database functions, and hiding the file location for security was what we needed for downloading wmv files from our members creations without prompting Media player as well as secure the file itself and use only database queries.
Something to the effect below, very customizable for private access, remote files, and keeping order of your online media. Of course you need to setup the DB, table, and columns.
I have a link on my site to a script that outputs an XML file to the browser with the below code: However, if this setting is checked, and browser windows are being re-used, then it will open up on top of the page where the link was clicked to access the script. But, if the setting is unchecked, the output XML file will open up in a new window and there will be another blank window also open that has the address of the script, in addition to our original window.
This is far from ideal, and there is no way of knowing whether users have this option checked or not.
But there are some headers, which PHP itself outputs automatically, disturbing this. So I wrote this function with erasing these.
I think that readfile suffers from the maximum script execution time. The readfile is always completed even if it exceed the default 30 seconds limit, then the script is aborted. Be warned that you can get very odd behaviour not only on large files, but also on small files if the user has a slow connection.
I wasted days trying to figure this out before I found the problem was easily solved. I'm sure many of you out there have had similar problem when trying to use readfile to output images with a php file as the "src" of a "img" tag.
It works fine "as is" in Firefox but not in IE, Safari or g. I found hundreds of results on google all saying things like "there must be white space at the end of you code", "you need this header or that header". I couldn't believe what the solution was but here it is anyway!
Remove the "Width" and "Height" attributes from your "img" tag. Test especially for strings like ".. If possible only permit characters a-z, A-Z and and make it possible to only download from one "download-folder". Beware - the chunky readfile suggested by Rob Funk can easily exceed you maximum script execution time 30 seconds by default.
I didn't benchmark further, but I'd be willing to bet non-mmap'able streams still win because they can loop in C instead of PHP. If you are using the procedures outlined in this article to force sending a file to a user, you may find that the "Content-Length" header is not being sent on some servers.
The reason this occurs is because some servers are setup by default to enable gzip compression, which sends an additional header for such operations.
This additional header is "Transfer-Encoding: Of course, this is not required if you are using the intelligent versions of readfile in this article.
With PHP's authentication and file manipulation functions, you have full control over who is allowed to upload and what is to be done with the file once it has been uploaded. Example 1 File Upload Form. A file upload screen can be built by creating a special form which looks something like this:.
This form element should always be used as it saves users the trouble of waiting for a big file being transferred only to find that it was too large and the transfer failed. Keep in mind: It is merely a convenience feature for users on the client side of the application. The PHP settings on the server side for maximum-size, however, cannot be fooled.
Its contents from the example form is as follows. Note that this assumes the use of the file upload name userfile , as used in the example script above. This can be any name. The mime type of the file, if the browser provided this information. This mime type is however not checked on the PHP side and therefore don't take its value for granted.
The temporary filename of the file in which the uploaded file was stored on the server. The error code associated with this file upload. Setting it using putenv from within a PHP script will not work. This environment variable can also be used to make sure that other operations are working on uploaded files, as well.
Example 2 Validating file uploads. The following example will process the file upload that came from a form. The PHP script which receives the uploaded file should implement whatever logic is necessary for determining what should be done with the uploaded file.
