Laravel - Collections - Method Search

The search method searches the collection for the given value and returns its key if found. If the item is not found, false is returned:

    $collection = collect([2, 4, 6, 8]);
    // 1

The search is done using a "loose" comparison, meaning a string with an integer value will be considered equal to an integer of the same value. To use "strict" comparison, pass true as the second argument to the method:

    collect([2, 4, 6, 8])->search('4', $strict = true);
    // false

Alternatively, you may provide your own closure to search for the first item that passes a given truth test:

    collect([2, 4, 6, 8])->search(function ($item, $key) {
        return $item > 5;
    // 2
