Passing class to Function

I'm using php_serial.class.php, called once

require_once("php_serial.class.php");

and call it $serial:

$serial = new phpSerial;

The above are in a global.php file that sets up the serial com parameters.

In another file, I include global.php that contains my other code to send and read from the class

In a function, I pass the class:

Function checkInput($serial){

And one in the Function:

$read = $serial->readPort();

This throws an error: "PHP Fatal error: Uncaught Error: Call to a member function readPort() on string"

If I do the $read outside of the Function, it doesn't throw the error so I assume I'm doing something wrong passing the class to the function?

Correct. Apparently you're calling checkInput() with a string instead of a phpSerial object.
