How to Delete an Element from an Array in PHP

Piper June 10, 2021

The PHP built-in function unset() is used to delete an element from an array in PHP. The unset() function in PHP can also use to destroy any other variable. The unset command inputs the array key as input and removed the element from that array.

Delete an element from a single-dimensional array:

     <?php
        $array = array('blue', 'green', 'yellow', 'red', 'violet');
        unset($arr2[1]); //RESULT: array(0 => 'blue', 2 => 'yellow', 3=> 'red', 4=>'violet')
    ?>

Delete an element from a multidimensional array

     <?php
        $array = array("a" => "Apple", "b" => "Ball", "c" => "Cat");
        unset($arr1["a"]);
        // RESULT: array("b" => "Ball", "c" => "Cat")
    ?>
