PHP: Return the current key and value pair from an array

The each() function is used to fetch the key and value of the current element. The function also moves the internal array pointer forward.

Note: After each() has executed, the array cursor will be left on the next element of the array, or past the last element if it hits the end of the array. You have to use reset() if you want to traverse the array again using each.

Version

Syntax:

each(array_name)

Parameter:

Name	Description	Required / Optional	Type
array_name	The input array.	Required	Array

Return value:

The current key and value pair from array_name.

Example:

<?php
$subject= array('Language','English','Math','Science');
$result = each($subject);
print_r($result);
?>

Output:

Array ([1] => Language [value] => Language [0] => 0 [key] => 0)
