Use PHP to Remove Element From Array – Examples

Let’s take a look at how to remove element from array by using an easy to follow example. Let’s consider that we have an array of fruits & we have a vegetable ( an array item ) that we would like to delete from the array. We are going to look at two ways to delete the array item. The first way would be to use the index of the array element to remove the array element directly. The second way is to use specified key to remove the array item.

Example 1: Use Index to Remove Array element using PHP

<?php 
$fruits = array('apple', 'mango', 'grapes', 'pineapple', 'potato');

//Using index to remove array element
unset( $fruits[4] );

echo '<pre>Result after Using index to remove array element<br />';
print_r($fruits);
echo '</pre>';

//Output
Array
(
&nbsp; &nbsp; [0] => apple
&nbsp; &nbsp; [1] => mango
&nbsp; &nbsp; [2] => grapes
&nbsp; &nbsp; [3] => pineapple
)
?>

Example 2: Use specified key to delete array element using PHP

<?php
//Using the specified key to delete array element
$fruits = array('fruit1' => 'apple', 'fruit2' => 'mango', 'fruit3' => 'grapes', 'fruit4' => 'pineapple', 'fruit5' => 'potato');

unset( $fruits['fruit5'] );

echo '<pre>Result after Using specified key to delete array element<br />';
print_r($fruits);
echo '</pre>';

//Output
Array
(
    [fruit1] => apple
    [fruit2] => mango
    [fruit3] => grapes
    [fruit4] => pineapple
)
?>
