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.

Return Values

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.
