gettype

(PHP 3, PHP 4, PHP 5)

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:

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_int(), is_null(), is_numeric(), is_object(), is_resource(), is_scalar(), and is_string().
