I have a thing I dont get. I found this regex part to check for correct subdomains. function check_subdomain($data){ if (!empty($data)){ $data = preg_match("/^(?:[A-Za-z0-9][A-Za-z0-9\-]{0,61}[A-Za-z0-9]|[A-Za-z0-9])$/", $data); return($data); } else { } } echo check_subdomain($data); but the strange thing is that echo check_subdomain($data) outputs the input and adds a 0 when wrong and a 1 when correct. why is this done and how to avoid it?

hi, i have a preg_match that checks "descriptions". the preg_match fails when i input an apostrophe ' in the text box. my code is as follows: $clean_description_step01 = htmlentities($thisValue, ENT_QUOTES);$clean_description_step02 = stripslashes($clean_description_step01); if(preg_match("/^[-',.a-z0-9dws]{1,200}$/i",$clean_description_step02)) { do something here...} can any one see why its not working?
