how to add Arabic letters to url regex
I have been searching a couple of hours without an answer.
How do you use preg_replace on arabic characters as well as english?
this is my code is english
$string = preg_replace ( "/&([a-zA-Z])(uml|acute|grave|circ|tilde|ring),/", "", $string );
$string = preg_replace ( "/[^a-zA-Z0-9_.-]/", "", $string );
some of the answers suggested i use this code:
$string = preg_replace ( "/&([أ-يa-zA-Z])(uml|acute|grave|circ|tilde|ring),/u", "", $string );
$string = preg_replace ( "/[^أ-يa-zA-Z0-9_.-]/u", "", $string );
I have tested it and it works. but is this actually functional for php? does it include all arabic characters? is there a better way to include all arabic characters?
What i am going to do with the code is:
Replace all characters in the string to valid SEO friendly characters.
I solved the problem using this code based on http://www.unicodemap.org. Thank you Bryan.
$string = preg_replace ( "/&([\x{0600}-\x{06FF}a-zA-Z])(uml|acute|grave|circ|tilde|ring),/u", "", $string );
$string = preg_replace ( "/[^\x{0600}-\x{06FF}a-zA-Z0-9_.-]/u", "", $string );
