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
comparision .
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_integer(),
is_null(), is_numeric(), is_object(),
is_resource(), is_scalar() and is_string().
