PHP each() Function

PHP each() Function

Hello folks! welcome back to a new edition of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP each() Function.

The each() function returns the current key and value pair from an array and advances the array cursor.

Warning: This built-in PHP function has been DEPRECATED as of PHP 7.2.0, and REMOVED as of PHP 8.0.0. Relying on this function is highly discouraged.


Following below is the syntax to use this function -

each ( $array );

Parameter Details

Sr.NoParameter & Description


It specifies an array

Return Value

This built-in function returns the current key and value pair from the array array. This pair is returned in a four-element array, with the keys 0, 1, key, and value. Elements 0 and key contains the key name of the array element, and 1 and value contain the data.

But if the internal pointer for the array point past the end of the array contents, it returns false.


Try out the below example -

   $transport = array('foot', 'bike', 'car', 'plane');
   $key_value = each($transport);
   print "<br />";
   $key_value = each($transport);
   print "<br />";
   $key_value = each($transport);


When the above code is executed, it will produce the following result -

Array ( [1] => foot [value] => foot [0] => 0 [key] => 0 )
Array ( [1] => bike [value] => bike [0] => 1 [key] => 1 )
Array ( [1] => car [value] => car [0] => 2 [key] => 2 )

Alright guys! This is where we are going to be rounding up for this tutorial post. In our next tutorial, we are going to be discussing about the PHP end() Function.
