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().
