array each(array array);Returns the current key/value pair from the array array and advances the array cursor. This pair is returned in a four-element array, with the keys 0, 1, key, and value. 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:
$foo = array( "Robert" => "Bob", "Seppo" => "Sepi" );
$bar = each( $foo );
$bar now contains the following key/value pairs:

each() is typically used in conjunction with list() to traverse an array; for instance, $HTTP_POST_VARS:
Example 2. Traversing $HTTP_POST_VARS with each() echo "Values submitted via POST method:<br>";
while ( list( $key, $val ) = each( $HTTP_POST_VARS ) ) {
echo "$key => $val<br>";
}
