Note Submitter: t0rus@dr.com ---- //here's an example of how to check if the string has properly //closed brakets for ex. if it has (())(()(())) or ))(())((())))))) //using stack, returns true if the string is ok, //and false otherwise //it pushes "(" into stack if it finds it and pops it out if finds ")" after it //i'm not used to programming in php so, don't mind the //mistakes, if u've got any suggestions or questions go to my site - h**p://www.torsoft.tk function validate ($string){ $Stack=array(""); $i=-1; while ($i++<strlen($string)){ //checking the entire string $ft=substr($string,$i,1); if ($ft=="(") array_push($Stack,$ft); elseif ($ft==")") array_pop($Stack); } return sizeof($Stack)==0; }
