strpos(): Argument #2 ($needle) must be of type string, array given [duplicate]

Hi,

I have this code:

if ( strpos( $_GET[ 'y' ], array( '/', '.', '\\', '%', '#', ';' ) ) === false

it worked fine on php5 but now on php 8 I get this error:

 strpos(): Argument #2 ($needle) must be of type string, array given

do I have to get rid of that line altogether or is there any alternative fix out there?

Thank you.
