Remove Something From an Array

I am writing a class, that so far looks like this:

( The user is building a custom door )....


Anyways, I want a method to remove from the "KIT" a certain part number, like:

$myDoor->removePartFromKit("353325");  // the part number to remove

So how do I find the part number and remove it from my "KIT" array?

THanks!



class newDoor {

      var $door_type;
      var $kit;
      
      function AddPartToKit($p, $d, $pr){
            
            $this->kit[] = array("PartNumber" => $p, "Desc" => $d, "Price"  => $pr)      ;      
            
      }
      
      
      // Set Door Type
      function SetDoorType($dType) {
      
            $this->door_type = $dType;
      
      }

} // End Class

Hi,

You want something like below - this should go through everything in the kit array and retreive its key if the part number is the same as the part number submitted to the function
It then removes all the rows from the kit array where the part number was found (if any)

     function RemoveFromKit($KitPartNumber){
          foreach($this->kit as $key=>$value){
                if ($value['PartNumber'] == $KitPartNumber){
                    $arrayToRemove[] = $key;
                }
          }
          if (isset($arrayToRemove)) {
                foreach($arrayToRemove as $key=>$value){
                    unset($this->kit[$value]);
                }
          }
     }
