Laravel Collection difference between contains() & containsStrict() Methods

In this post, we will see about difference between contains() & containsStrict() Methods

contains() Method #

if we Look contains() method Syntax:

/**
     * Determine if an item exists in the enumerable.
     *
     * @param  mixed  $key
     * @param  mixed  $operator
     * @param  mixed  $value
     * @return bool
     */
    public function contains($key, $operator = null, $value = null);

contains() if an element exists in the collection matching a given truth other wise it return false .let see example

$collection = collect([
        'apple',
        'samsung',
        'xiaomi',
        'oppo'
    ]);
$collection->contains('apple'); //true

$collection->contains('htc'); //false

we can see apple is exists then it will return true and htc not exists then it will return false

Great breakdown! The contains() method checks if a value exists in a Laravel collection, making it useful for quick lookups. However, it uses loose comparison, meaning type differences may not matter. For stricter checks, containsStrict() ensures both value and type match. Perfect for avoiding unintended matches!
