efficient way to search object in an array by a property

Question

well, having something like:

$array[0]->id = 'one'; $array[0]->color = 'white'; $array[1]->id = 'two'; $array[1]->color = 'red'; $array[2]->id = 'three'; $array[2]->color = 'blue'; 

what would be the fastest, most efficient way to implement a method like

function findObjectById($id){}

that would return the object $array[0] if i called:

$obj = findObjectById('one') 

and would return false if i passed 'four' as a param.

Answer 1

You can iterate that objects:

function findObjectById($id){     $array = array( /* your array of objects */ );      foreach ( $array as $element ) {         if ( $id == $element->id ) {             return $element;         }     }      return false; } 

Edit:

Faster way is to have an array with keys equals to objects' ids (if unique);

Then you can build your function as follow:

function findObjectById($id){     $array = array( /* your array of objects with ids as keys */ );      if ( isset( $array[$id] ) ) {         return $array[$id];     }      return false; }
