Disabling the PHP Version Check

  • How is it possible to disable the PHP Version check for a Plugin globally? I need this temporary to update a plugin to the last functional PHP 5.6 version, which I can’t do anymore since the current version don’t allow any updates, even no older versions. Changing and downgrading the “Requires PHP:” entry inside the “readme.txt” of the plugin should normally work but unfortunately the plugin is too big for uploading on the server and I can’t raise the PHP Upload size more than 16 MB from my hosting panel. So I get the error message “The link you followed has expired”. I also try to upload a php.ini file with the values and edit the .htaccess with every suggestions from this website which results in an “Internal Server Error”.

    So my last hope it to disable the PHP Version check from WordPress installation to update the plugin directly from admin panel without any PHP warnings but how can I do this and which files do I have to edit?

  • I looked at wp code and there are no filters and it is a core function, but it is easy to temporarily hack.

    File

    wp-includes/functions.php

    change around line 8026

    function is_php_version_compatible( $required ) {
	return empty( $required ) || version_compare( phpversion(), $required, '>=' );
}

    to 

    function is_php_version_compatible( $required ) {
	return true;
}

    Of course this is a temporary hack, will be overwritten by a new update and your security software may well detect core file changes.

    Do on a test system first – or make sure you have a working back up just in case.

    Just as an aside – Changing and downgrading the “Requires PHP:” entry inside the “readme.txt” of the plugin

    The check is actually done against the plugin main php file header not the readme.txt – I know lots of devs put it in the readme.txt but that is not actually the right place
