In this tutorial, I’ll show you eight different ways to add to, remove from and insert elements to/from an array in PHP. PHP array functions used include: array(), array_push(), array_unshift(), array_pop(), array_shift(), array_slice(), count(), array_diff() and array_splice().
Let’s start with our original array:
<?php
// Our original array
$array = array('one', 'two', 'three');Here’s how you add elements to the end of a PHP array:
<?php // Add elements to end of array array_push($array, 'four', 'five');
Here’s how to elements to the beginning of a PHP array:
<?php // Add elements to beginning of array array_unshift($array, 'zero');
Here’s how to remove a single element from the end of an array:
<?php // Remove one element from end of array array_pop($array);
Here’s how to remove a single element from the beginning of an array:
<?php // Remove one element from beginning of array array_shift($array);
Here’s how to GET multiple elements from the end of an array:
<?php // Get multiple elements from end of array $lasttwo = array_slice($array, -2);
Here’s how to remove multiple elements from the end of an array and return what’s left:
<?php // Remove multiple elements from end of array $length = count($array); $slice = array_slice($array, 0, $length-2);
Here’s how to remove specific elements (by value) from a PHP array:
<?php
// Remove specific elements from an array
$diff = array_diff($array, array('one', 'four'));Here’s how to insert an element anywhere into an array:
<?php // Insert element anywhere in array array_splice( $array, 2, 0, 'inserted');
