Traversing Arrays Using list() and each() in PHP

Although foreach() is the nicer way of iterating over an array, an additional way of traversing an array is by using a combination of the list() construct and the each() function:

$players = array("John", "Barbara", "Bill", "Nancy");
reset($players);
while (list($key, $val) = each($players)) {
    print "#$key = $val\n";
}

The output of this example is

#0 = John
#1 = Barbara
#2 = Bill
#3 = Nancy
