To remove the last element or value from an array, array_pop() function is used. This function returns the last removed element of the array and returns NULL if the array is empty, or is not an array. After removing the last element from the array, the array is modified, and the index is reduced by one from last, only if the keys are numerical.
It is an inbuilt array function of PHP, which deletes the last element of an array.
The array_pop() function, which is used to remove the last element from an array, returns the removed element. It also returns NULL, if the array is empty, or is not an array.
<?php $car = array("Mercedes", "Creta", "Audi", "Chevrolet", "Skoda"); echo "Arraylist: "; print_r($car); $remove = array_pop($car); echo "</br>Removed element from array is: "; print_r($remove); echo "</br> Updated arraylist: "; print_r($car); ?>
An element "Skoda" is removed from the end of the given array, and the updated list is displayed in the given output.
Example: Using numeric keys
<?php $mall = array(1 => "DLF", 2 => "GIP", 3 => "V3S"); echo "Removed element: ".array_pop($a). "</br>"; print_r($mall); ?>
Example: Using numeric values
<?php $numbers = array(45, 76, 23, 91, 82, 39); $removed = array_pop($numbers); echo "Removed array element is: ". $removed; echo "</br> Update array is: "; print_r($numbers); ?>
An element 39 is removed from the end of the given array, as you can see in the below output.
