How to Delete an Element from an Array in PHP
In this post we will give you information about How to Delete an Element from an Array in PHP. Hear we will give you detail about How to Delete an Element from an Array in PHPAnd how to use it also give you demo for it if it is necessary.
Use the PHP unset() Function
If you want to delete an element from an array you can simply use the unset() function.
The following example shows how to delete an element from an associative array and numeric array.
<?php
$arr1 = array("a" => "Apple", "b" => "Ball", "c" => "Cat");
unset($arr1["b"]);
// RESULT: array("a" => "Apple", "c" => "Cat")
$arr2 = array(1, 2, 3);
unset($arr2[1]);
// RESULT: array(0 => 1, 2 => 3)
?>If you see the above example carefully you will find that the unset() function didn’t reindex the array after deleting the value from the numeric array (line no-8). To fix this you can use the array_splice() function. It takes three parameters: an array, offset (where to start), and length (number of elements to be removed). Let’s see how it actually works:
<?php
$arr = array(1, 2, 3);
array_splice($arr, 1, 1);
// RESULT: array(0 => 1, 1 => 3)
?>
