How to search for an element in a collection and get its index in illuminate/collections?

In Illuminate/Collections, you can use the search() method to find an element in a collection and retrieve its index.

Here's an example:

use Illuminate\Support\Collection;

$collection = collect([2, 4, 6, 8, 10]);

$index = $collection->search(6);

// The search() method will return the index if the element is found 
// or false if the element is not present in the collection.

if ($index !== false) {
    echo "The element 6 is found at index: " . $index;
} else {
    echo "The element 6 is not present in the collection.";
}

Output:

The element 6 is found at index: 2

If the element is not found, the search() method will return false, which allows you to handle cases where the element is not present in the collection.
