(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:

" 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.
