This means that setting a limit higher than about 2.1 GB will result in PHP seeing a large negative number. PHP directive values are expressed in bytes. memorylimit, which should be larger than postmaxsize. You may also have to adjust other directives, including: postmaxsize, which must be larger than uploadmaxfilesize.
Php file upload limit how to#
The file above is a diff on 5.2.10 code, but I just made the changes by hand to 5.2.17 code and i just uploaded a 3.4gb single file through apache/php (which hadn't worked before the change). PHP How to increase the files upload limit in PHP How to increase the files upload limit in PHP By: CodexWorld Last Updated: Share When you are working with multiple files upload in PHP, it is necessary to increase the maximum number of files to upload. 16 amalcon at eudoramail dot com 18 years ago Note that, when you want to upload VERY large files (or you want to set the limiters VERY high for test purposes), all of the upload file size limiters are stored in signed 32-bit ints. The PHP default is 2 Megabytes, and you will have to increase it if you want to upload larger files via a PHP web application. Once finished editing this line, save and close the php.ini file. To increase this value, simply change '2' to a higher number value such as '10' which would allow for a maximum upload limit of 10mb. So.for this to work, you need to edit the PHP code and compile it by hand (make sure you compile it as 64-bit). uploadmaxfilesize 2M The value '2' represents the maximum size of your file in Megabytes (MB). that need to be changed from int to long. memorylimit You’ll want to make sure your script memory limit is set to a decent size, probably larger than either of the other two settings. uploadmaxfilesize This value sets the maximum size of an upload file. even if you're on a 64-bit system and have a version of PHP compiled with 64-bit, there are several problems.įirst, the code that converts post_max_size and others from ascii to integer stores the value in an int, so it converting "9G" and putting the result into this int will bork the value because 9G is a larger number than a 32-bit variable can hold.īut there are also several other areas of PHP code that are used with the Apache module, CGI, etc. postmaxsize This setting controls the size of an HTTP post, and it needs to be set larger than the uploadmaxfilesize setting. I don't know about in 5.3.x, but in 5.2.x there are some int/long issues in the PHP code.
