Compare array php foreach loop -

i have 2 arrays , want create output array.

example array requirements title , subtitle field:

array ( [title] => array     (         [required] => 1         [minlength] => 2         [maxlength] => 50     )  [subtitle] => array     (         [required] => 1         [minlength] => 2         [maxlength] => 55     )  ) 

post array after post s:

array (     [title] =>      [subtitle] => s ) 

example output array:

array ( [title] => array     (         [0] => field required         [1] => must longer 2     )  [subtitle] => array     (                     [0] => must longer 2     )  ) 

how can generate such array foreach loop?

this have, wont work well. if leave title blank , subtitle 1 character gives 2 times field required. looks duplicated.

class forms_formvalidationfields {  private $_required; private $_minlength; private $_maxlength; private $_alphanumeric; public $_errors;  public function __construct($validate, $posts) {      array_pop($posts);     $posts = array_slice($posts,1);      foreach ( $posts $postname => $postvalue) {         foreach( $validate[$postname] $key => $rulevalue ){             $set = 'set'.ucfirst($key);             $get = 'get'.ucfirst($key);              $this->$set( $postvalue , $rulevalue);             if( $this->$get() != '' || $this->$get() != null) {                 $test[$postname][] .= $this->$get();             }         }                 }      $this->_errors = $test; } public function setvalidation(){     return $this->_errors; } public function getrequired() {     return $this->_required; }  public function setrequired($value, $rulevalue) {     if (empty($value) && $rulevalue == true) {         $this->_required = 'this field required';     } }  public function getminlength() {     return $this->_minlength; }  public function setminlength($value, $rulevalue) {     if (strlen($value) < $rulevalue) {         $this->_minlength = ' must longer than' . $rulevalue . '';     } }  public function getmaxlength() {     return $this->_maxlength; }  public function setmaxlength($value, $rulevalue) {     if (strlen($value) > $rulevalue) {         $this->_maxlength = 'must shorter than' . $rulevalue . '';     } }  } 

here go:

<?php     $required = array(         'this field not required',         'this field required'     );      $length = 'requires more {less} less {more}';      $needs = array(         'title' => array(             'required' => 1,             'minlength' => 2,             'maxlength' => 50,         ),          'subtitle' => array(             'required' => 1,             'minlength' => 2,             'maxlength' => 55         )     );      $new_needs = array();      foreach($needs $key => $value) // loop on array     {         $new_needs[$key][] = $required[$value['required']];         $new_needs[$key][] = str_replace(             array('{more}', '{less}'),             array($value['maxlength'], $value['minlength']),             $length         );     }      foreach($_post $key => $value)     {         if(empty($value)) { echo $new_needs[$key][0]; }          if(strlen($value) > $needs[$key]['maxlength'] || strlen($value) < $needs[$key]['minlength']) echo $new_needs[$key][1];     } 

should pretty self explanatory if read on it.

result:

array (     [title] => array         (             [0] => field required             [1] => requires more 2 less 50         )      [subtitle] => array         (             [0] => field required             [1] => requires more 2 less 55         )  )
