PHP array_pop() function

Syntax

PHP array_pop() function has the following syntax.

Definition

The array_pop() function returns the value from the end of the array and removes it from the array.

array_pop() is the counterpart to array_shift();

Parameter

• array - Required. Array to popup

Note

array_push() and array_pop() are useful for creating a stack which is a last-in, first-out (LIFO) structure. We can add new values onto the "top" of the stack with array_push(), then retrieve the most recently added value with array_pop().

Example

Popup value from an Array

<?PHP/*w w  w. j a  va  2  s  .  c om*/
$names = array("Java", "PHP", "Python", "HTML","java2s.com", "CSS");
$firstname = array_pop($names);
print($firstname);
print_r($names);
?>

The code above generates the following result.

Example 2

Popup element from associate array

<?PHP/*from www  . j av  a2s.  c  om*/
$myBook = array( "title" =>  "Learn PHP from java2s.com", 
                 "author" =>  "java2s.com", 
                 "pubYear" =>  2000 ); 

echo array_pop( $myBook ) . "\n";
print_r( $myBook );       
?>

The code above generates the following result.
