php - How to best use OOP principles to deal with a case of having 10-15+ matching criteria that all need to be passed? -

i have class takes in lines of text , uses 15 different "criteria" (individual preg_match statements) check if line should qualify saved in array.

how 1 best handle such situation clean, maintainable code?

initially had crazy long if statement had criteria, example:

if (     preg_match($criteria1,$line) &&     preg_match($criteria2, $line) &&     ...     ...     ...     preg_match($criterian,$line) ) {     //do something, e.g. save line array. } 

i've since put each preg_match statement different function within separate class , call each function in row, checking if it's true... have 15 separate functions subtly different each other , still doesn't feel i'm writing code. how best handle situation?

well, if want keep things object oriented, use class this...

class validator{      /* criteria needing met must exist in array */     public static $criterias = array($criteria1,                                       $criteria2,                                       ... ,                                       $criterian);        public static function validate($line){          /* make sure line meets each criteria */         foreach(validator::$criterias $criteria){                if(!preg_match($criteria, $line))                    return false;         }          return true;     } 

it makes sense have methods , properties static because unique no instance. can check see if line meets criteria calling

validator::validate($line)
