How to Remove Specific Element from an Array in PHP - Step by Step Examples

How to Remove Specific Element from an Array in PHP ?

Answer

To remove a specific element from an array in PHP, you can use the `unset` function or create a new array excluding the element to be removed.

✐ Examples

1 Remove Element using unset function

In this example,

We create an array named `$numbers` with elements including the one to be removed.
We use the `unset` function to remove the specific element from the array.
Finally, we get an array without the specific element.

PHP Program

<?php 
$numbers = [1, 2, 3, 4, 5];
$indexToRemove = array_search(3, $numbers);
unset($numbers[$indexToRemove]);
$numbers = array_values($numbers);
echo 'Array after removing 3: ';
print_r($numbers);
?>

Output

Array after removing 3: Array
(
    [0] => 1
    [1] => 2
    [2] => 4
    [3] => 5
)

2 Remove Element by creating a new array

In this example,

We create an array named `$colors` with elements including the one to be removed.
We use a loop to create a new array excluding the specific element.
Finally, we get a new array without the specific element.

PHP Program

<?php 
$colors = ['red', 'green', 'blue', 'yellow'];
$elementToRemove = 'green';
$newArray = [];
foreach ($colors as $color) {
    if ($color !== $elementToRemove) {
        $newArray[] = $color;
    }
}
echo 'Array after removing ' . $elementToRemove . ': ';
print_r($newArray);
?>

Output

Array after removing green: Array
(
    [0] => red
    [1] => blue
    [2] => yellow
)
