at HandleExceptions->handleError('2', 'preg_replace(): Compilation failed: invalid range in character class at offset 13', '/app/Http/Controllers/Controller.php', '217', array('string' => 'gegegeg', 'separator' => '-'))

at call_user_func_array(array(object(AdsController), 'FormAds'), array('main_id' => '14', 'sub_id' => '71', 'typ_id' => '97', object(Request))) in Controller.php line 80

Code

 echo preg_replace('/[^a-z0-9_-s-ءاأإآؤئبتثجحخدذرزسشصضطظعغفقكلمنهويةى]/u', '', 'gegegeg');

Error:

You need to escape hyphens now, so just add one after your \s

'/[^a-z0-9_\-\s\-ءاأإآؤئبتثجحخدذرزسشصضطظعغفقكلمنهويةى]/u'

See this answer preg_match(): Compilation failed: invalid range in character class at offset
