Laravel 5: Retrieving, and Removing an Element From an Array With pull

The pull helper method is similar to the get method in that it will return a value for the given $key in the $array (or the $default, if it is specified and the $key does not exists). The difference is that the pull method will remove the item it finds from the array.

#Signature

The signature of the pull method is:

1public static function pull(
2    &$array,
3    $key,
4    $default = null
5);

#Example Use

Consider the following array, which is probably familiar to most people these days:

1$weekDays = [
2    1 => 'Sunday',
3    2 => 'Monday',
4    3 => 'Tuesday',
5    4 => 'Wednesday',
6    5 => 'Thursday',
7    6 => 'Friday',
8    7 => 'Saturday'
9];

A lot of people do not like Mondays. Let's demote Monday to the $theWorstDayOfTheWeek while also removing it from our $weekDays:

1use Illuminate\Support\Arr;
2
3// Demote 'Monday'
4$worstDayOfTheWeek = Arr::pull($weekDays, 2);

The $weekDays array would now look like this:

1array {
2    [1] "Sunday"
3    [3] "Tuesday"
4    [4] "Wednesday"
5    [5] "Thursday"
6    [6] "Friday"
7    [7] "Saturday"
8}

#Global array_pull Helper Function

The array_pull function is a shortcut to calling Arr::pull. This function is declared in the global namespace.
