How to use the search () method in the Laravel collection

This article will explain in detail how to use the search () method in the Laravel collection. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Search ()

The search method can find the collection with a given value. If this value is in the collection, the corresponding key is returned. If no data item matches the corresponding value, false is returned.

$names = collect (['Alex',' John', 'Jason',' Martyn', 'Hanlin']); $names- > search (' Jason'); / / 2

The search method uses loose comparisons by default. You can use strict comparison by passing true in its second parameter.

You can also pass your own callback function to the search method. The key of the first item that passes the callback truth test is returned.

Names = collect (['Alex',' John', 'Jason',' Martyn', 'Hanlin']); $names- > search (function ($value, $key) {return strlen ($value) = = 6;}) / 3 this is the end of the article on "how to use the search () method in the Laravel collection".
