                                    gettype

   (PHP 3, PHP 4 )
   gettype -- Get the type of a variable

Description

   string gettype ( mixed var)

   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.

   Possibles values for the returned string are:

     * "boolean" (since PHP 4)
     * "integer"
     * "double" (for historical reasons "double" is returned in case of a
       float, and not simply "float")
     * "string"
     * "array"
     * "object"
     * "resource" (since PHP 4)
     * "NULL" (since PHP 4)
     * "user function" (PHP 3 only, deprecated)
     * "unknown type"

   For PHP 4, you should use function_exists() and method_exists() to
   replace the prior usage of gettype() on a function.

   See also settype(), is_array(), is_bool(), is_float(), is_integer(),
   is_null(), is_numeric(), is_object(), is_resource(), is_scalar(), and
   is_string().
