## Example

`

     string gettype ( mixed $var )

`

## Description

Returns the type of the PHP variable var. Warning Never use gettype() to test for a certain type, since the returned string may be subject to change in a future version. In addition, it is slow too, as it involves string comparison. Instead, use the is_* functions.

## Return Values

Possibles values for the returned string are: "boolean" "integer" "double" (for historical reasons "double" is returned in case of a float, and not simply "float") "string" "array" "object" "resource" "NULL" "unknown type"
