For searching an object in array I made the ObjectArray class. An instance of this class is an array which contains the objects as strings which makes searching for objects possible.

<?php
class ObjectArray {
    var $objectArray = array();
    function ObjectArray() {
        
    }
    function inArray($object) {
        $needle = $this->object2String($object);
        return in_array($needle, $this->objectArray);
    }
    function object2String($object) {
        $str = "";
        $vars = get_object_vars($object);
        foreach ($vars as $value)
            $str .= (is_object($value)) ? $this->object2String($value) : $value;
        return $str;
    }
    function addObject($object) {
        $str = $this->object2String($object);  
        array_push($this->objectArray, $str);
    }
}
?>

You can use this class like:

<?php
$objectArray = new ObjectArray();
$myFirstCar = new Car("brown", 20);
$objectArray->addObject($myFirstCar);
$mySecondCar = new Car("red", 160);
$objectArray->addObject($mySecondCar);
?>

This example uses the Car class:

<?php
class Car {
    var $color;
    var $speed;
    function Car($color, $speed) {
        $this->color = $color;
        $this->speed = $speed;
    }    
}
?>

The next code shows an example if we were searching for my first car:

<?php
if ($objectArray->inArray($myFirstCar)) {
  echo "I've found your first car!";
}
?>
