Here is print_r output of my array:

Array
(
[0] => stdClass Object
    (
        [itemId] => 560639000019
        [name] => Item no1
        [code] => 00001
        [qty] => 5
        [id] => 2
    )

[1] => stdClass Object
    (
        [itemId] => 470639763471
        [name] => Second item
        [code] => 76347
        [qty] => 9
        [id] => 4
    )

[2] => stdClass Object
    (
        [itemId] => 56939399632
        [name] => Item no 3
        [code] => 39963
        [qty] => 6
        [id] => 7
    )

)

How can I find index of object with [id] => 4 in order to remove it from array?

In my case, this my array as $array
I was confused about this problem of my project, but some answer here helped me.

array(3) { 
           [0]=> float(-0.12459619130796) 
           [1]=> float(-0.64018439966448) 
           [2]=> float(0)
         }

Then use if condition to stop looping

foreach($array as $key => $val){
           if($key == 0){ //the key is 0
               echo $key; //find the key
               echo $val; //get the value
           }
        }

I know, after so many years this could be a useless answer, but why not?

This is my personal implementation of a possible index_of using the same code as other answers but let the programmer to choose when and how the check will be done, supporting also complex checks.

if (!function_exists('index_of'))
{
    /**
     * @param iterable $haystack
     * @param callable $callback
     * @param mixed|null &$item
     * @return false|int|string
     */
    function index_of($haystack, $callback, &$item = null)
    {
        foreach($haystack as $_key => $_item) {
            if ($callback($_item, $_key) === true) {
                $item = $_item;
                return $_key;
            }
        }
        return false;
    }
}
