[FIX] Warning: preg_replace(): The /e modifier is no longer supported, use preg_replace_callback instead

[XONOSNET]

I just wanted to document this fix because I know it can be annoying when testing/debugging. For those of you that are trying to use the older adLDAP library with newer versions of PHP, the following warning will often occur.

Warning: preg_replace(): The /e modifier is no longer supported, use preg_replace_callback instead in lib\adLDAP\classes\adLDAPUtils.php on line 105

To fix this, navigate to the adLDAP\classes\adLDAPUtils.php file and modify the following:

Line: 102

public function ldapSlashes($str){
    return preg_replace('/([\x00-\x1F\*\(\)\\\\])/e',
                        '"\\\\\".join("",unpack("H2","$1"))',
                        $str);
}

Change to this:

public function ldapSlashes($str){
    return preg_replace_callback('/([\x00-\x1F\*\(\)\\\\])/',
        function($matches) {
            foreach($matches as $match) {
                return join("", unpack("H2","$1"));
            }
        }, $str
    );
}
