Turning an Array into Variables
while (list($key, $value) = each($a))
<?php
$a = array('one' => 'I', 'two' => 'II', 'three' => 'III', 'four' => 'IV');
while (list($key, $value) = each($a)) {
echo htmlspecialchars("$key: $value") . '<br
/>';
}
?>
Looping through an Array with list() and each() (each-list.php)
Whenever each() is used, the use of list() is a good idea. Within list(), you provide variable names for all values with numeric indices in the array that is returned by each(). This makes while/each() loops even easier to use, as the code shows. Within the parentheses, the variable names are provided.
while (list(, $value) = each($a)) {
echo htmlspecialchars("$value") . '<br />';
}
