How to Remove the First Element from an Array in PHP



In this article, you will learn how to remove the first element from an array in PHP.

PHP array_shift() Function

In PHP, you can remove the first element of an array using the array_shift() function:

The array_shift() function takes the first element of an array and returns its value. This element is also removed from the original array. The function modifies the original array and returns the value of the removed element. If the array is empty, it returns NULL. array_shift re-indexes the remaining elements of the array so that the keys start from 0.

Example usage:

  $fruits = array("apple", "banana", "cherry", "orange");
  $first_fruit = array_shift($fruits);

  echo $first_fruit . "\n";

This will output:

    [0] => banana
    [1] => cherry
    [2] => orange

As you can see, the first element of the array $fruits has been removed, and its value (“apple”) has been returned and assigned to $first_fruit. The remaining elements have been re-indexed to start from 0.
