A

You can get the total number of values in an array by using the count() function. Here is a PHP example script:

<?php 
$array = array("PHP", "Perl", "Java");
print_r("Size 1: ".count($array)."\n");
$array = array();
print_r("Size 2: ".count($array)."\n");
?>

This script will print:

Size 1: 3
Size 2: 0

Note that count() has an alias called sizeof().
