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
