count()

count - Count all elements in an array, or properties in an object

Syntax

int count (mixed $var, int $mode)

Arguments

• var - The array.
• mode - 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. count() does not detect infinite recursion.

Description

Counts all elements in an array, or properties in an object.

Version

PHP 4, 5

Return value

Returns the number of elements in var, which is typically an array, since anything else will have one element.
