php - Undefined variable with $_GET? -

-

i have problem in php:

notice: undefined variable: _get in /.../script/install.php  on line 3

and code in line 3:

if($_get['step']<1)

so problem?

variable names case sensitive in php.

if($_get['step']<1)

also, avoid notice level warnings, may want check existence of variable first:

if ((array_key_exists($_get, "step")) , ($_get['step']<1))
