Q

How To Get the Total Number of Values in an Array in PHP?

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().
