<?php
...
function wp_is_ini_value_changeable( $setting ) {
static $ini_all;
if ( ! isset( $ini_all ) ) {
$ini_all = false;
// Sometimes `ini_get_all()` is disabled via the `disable_functions` option for "security purposes".
if ( function_exists( 'ini_get_all' ) ) {
$ini_all = ini_get_all();
}
}
// Bit operator to workaround https://bugs.php.net/bug.php?id=44936 which changes access level to 63 in PHP 5.2.6 - 5.2.17.
if ( isset( $ini_all[ $setting ]['access'] ) && ( INI_ALL === ( $ini_all[ $setting ]['access'] & 7 ) || INI_USER === ( $ini_all[ $setting ]['access'] & 7 ) ) ) {
return true;
}
// If we were unable to retrieve the details, fail gracefully to assume it's changeable.
if ( ! is_array( $ini_all ) ) {
return true;
}
return false;
}
