==array_shift() function operates much like array_pop()==



<source lang="html4strict">

//array_shift() function removes one element from the left side of the array.
//All remaining array elements are shifted one unit toward the left side of the array.
//array_shift() has the same syntax as array_pop():
<?
$languages = array("Spanish", "English", "French", "Russian");
$a_language = array_shift($languages);
print_r($a_language);
?>

</source>

==array_shift( ) function returns the value from the front of the array while also removing it from the array.==



<source lang="html4strict">

<?
$names = array("Johnny", "Timmy", "Bobby", "Sam", "Tammy", "Joe");
$firstname = array_shift($names); // "Johnny"
var_dump($names);
?>

</source>
