each

each -- return next key/value pair from an array

WRONG! it returns the current pair and advances the pointer

Description

array each(array array);

Returns the next key/value pair from the array array. This pair is returned in a four-element array, with the keys 0, 1, key, and value.
^DITTO
Elements 0 and key each contain the key name of the array element, and 1 and value contain the data.

Example 1. each() examples

$foo = array( "bob", "fred", "jussi", "jouni" );
$bar = each( $foo );


$bar now contains the following key/value pairs:

      0 => 0

      1 => 'bob'

      key => 0

      value => 'bob'

$foo = array( "Robert", => "Bob", "Seppo" => "Sepi" );
SYNTAX ERROR: remove , after "Robert"
