gettype

(PHP 4, PHP 5)

gettype — Get the type of a variable

Opis

string gettype ( mixed $var )

Returns the type of the PHP variable var .

Ostrzeżenie

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.

Parametry

var: The variable being type checked.

Zwracane wartości

Possibles values for the returned string are:

"boolean"
"integer"
"double" (for historical reasons "double" is returned in case of a float, and not simply "float")
"string"
"array"
"object"
"resource"
"NULL"
"unknown type"
