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
