The following functions can be used for calculating no. of elements in an Array.
1. sizeof($array)
2. count($array)

Syntax
count($array, $mode );
Definition and Usage
Count elements in an array, or properties in an object.

If the optional mode parameter is set to COUNT_RECURSIVE (or 1), count() will recursively count the array. This is particularly useful for counting all the elements of a multidimensional array. The default value for mode is 0. count() does not detect infinite recursion.
Example
<?php $a[0] = 1; $a[1] = 3; $a[2] = 5; $result = count($a); print($result); ?>

This will produce following result:3
