# count

count -- count elements in a variable

## Description

`int count`(mixed var);

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

Returns 1 if the variable is not an array.

Returns 0 if the variable is not set.

Warning
count() may return 0 for a variable that isn't set, but it may also return 0 for a variable that has been initialized with an empty array. Use isset() to test if a variable is set.

See also: sizeof(), isset(), and is_array().
