depends on the method of upload really. For example within a standard HTML form you could add something like:

<input type="hidden" name="MAX_FILE_SIZE" value="50000" />

There are also options from within PHP itself that can usually be controlled through .htaccess files, like this:

php_value upload_max_filesize 5M
php_value post_max_size 5M

or through ini_set() - all depends on your setup really.

The most effective is to change the PHP ini. You need to set the following variables:

Check out this link for all the details, but it will depend on the MAX_FILE_SIZE for the form, the upload_max_filesize and post_max_size in php.ini. Some other parameters may come into play as well (e.g. max_input_time or memory_limit if the max file size is large enough).

Use if ($_FILE['yourfile']['size'] > (1024 * 5)) or restrict php using ini_set('upload_max_filesize', '5MB');
