this is a good php function when you want to know how many elements are in an array.


PHP CODE
<?php
$a[0] = 1;
$a[1] = 3;
$a[2] = 5;
$result = count($a);
// $result == 3

$b[0] = 7;
$b[5] = 9;
$b[10] = 11;
$result = count($b);
// $result == 3

$result = count(null);
// $result == 0

$result = count(false);
// $result == 1
?>


an easy one is this code also to help you explain how to use this function:

<?
$count = array('1','2','3');
echo '<h1>'.count($count).'</h1>';
?>

OUTPUT: 3
