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         


        

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;
}
