Laravel 5 Collections: Retrieving the Maximum Value of a Collection With max

April 22, 2018 —John Koster

The max method can be used to retrieve the maximum value of the given $key. By default, the $key is null and will function in a similar way to PHP's max function.

#Signature

1public function max(
2 $callback = null
3);

#Example Use

The following code example highlights the usage of max without specifying a $key:

1use Illuminate\Support\Collection;
2 
3// Create a new collection instance.
4$collection = new Collection([
5 0, 1, 2, 3, 4, 5
6]);
7 
8// 5
9$max = $collection->max();

After the above code has executed the $max variable would contain the value 5. The following code example shows how to use the max function when specifying a $key:

1use Illuminate\Support\Collection;
2 
3// Create a new collection instance.
4$collection = new Collection([
5 ['name' => 'Laravel', 'version' => '5.1'],
6 ['name' => 'Lumen', 'version' => '5.0']
7]);
8 
9// 5.1
10$max = $collection->max('version');
11 
12// Lumen
13$maxName = $collection->max('name');

After the above code has executed the $max variable would contain the value 5.1 and the $maxName variable would contain the value Lumen.
