Using PHP’s array_pop Function to Remove the Last Element from an Array

In PHP we often need to manipulate array data. To retrieve and remove the last element, PHP provides the convenient array_pop function.

Syntax of array_pop

<code>mixed array_pop ( array &$array )</code>

The function accepts an array by reference, removes its last element, and returns that element; if the array is empty it returns null.

Code example

<code>&lt;?php
// Define an array
$fruits = array("apple", "banana", "orange", "grape");

// Use array_pop to pop and return the last element
$last_fruit = array_pop($fruits);

// Output the popped element
echo "Popped element is: " . $last_fruit . "\n";

// Output the remaining array
echo "Remaining array:\n";
print_r($fruits);
?&gt;</code>

The code defines an array $fruits containing several fruit names, uses array_pop to remove the last element ("grape") and assigns it to $last_fruit , then prints the popped value and the remaining array.

Running the script produces the following output:

<code>Popped element is: grape
Remaining array:
Array
(
    [0] => apple
    [1] => banana
    [2] => orange
)
</code>

Thus, array_pop easily removes and returns the final element of an array, which is useful for array manipulation in PHP.
