How to find common items in two Laravel collection objects

I'm trying to compare 2 collections, and put all values present in both into another collection.

So given these collections:

$text1 = collect('burger', 'cheese', 'bread', 'ham');
$text2 = collect('cheese', 'bread', 'tomato');

I would like to extract 'cheese' and 'bread'

in this case you need intersect method:

The intersect method removes any values from the original collection that are not present in the given array or collection. The resulting collection will preserve the original collection's keys:

$text1Collection = collect('burger', 'cheese', 'bread', 'ham');
$text2Collection = collect('cheese', 'bread', 'tomato');

$resultCollection =$text1Collection->intersect($text2Collection);

You want the intersect method available on Collections:

$intersect = $text1->intersect($text2);

$intersect->all(); // [1 => 'cheese', 2 => 'bread']
