Description

Returns the type of the PHP variable var.

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