How to use array_shift() function In PHP
The array_shift() function removes the first element from an array and returns it. This function also re-indexes the array so that the keys start from 0 again.
Example: This example shows the implementation of the above-explained approach.
<?php
$arr = array(1, 2, 3, 4, 5, 6);
$removedElement = array_shift($arr);
echo "Removed element: " . $removedElement . "\n";
echo "Updated array: ";
print_r($arr);
?>
Output
Removed element: 1
Updated array: Array
(
[0] => 2
[1] => 3
[2] => 4
[3] => 5
[4] => 6
)
