Syntax
PHP array_pop() function has the following syntax.
mixed array_pop ( array &arr )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// ja va2 s. c om
$names = array("Java", "PHP", "Python", "HTML","java2s.com", "CSS");
$firstname = array_pop($names);
print($firstname);
print_r($names);
?>
