Warning: count(): Parameter must be an array or an object that implements Countable line 168

[compumatter]

Hello and thank you for this class.
I recognize its value

I have a few questions.

My goal is to be able to load perhaps 1 class for the body but with different variations (italic, bold etc).

So I believe I should be using multi_simul_fontdisplay(...

When I use your example:
include_once('myserverpath/class.fontperformance.php"); $ref= new Fontperformance; $apilink =array( "https://fonts.googleapis.com/css?family=Montserrat+Alternates", "https://fonts.googleapis.com/css?family=Rancho", "https://fonts.googleapis.com/css?family=Tangerine", "https://fonts.googleapis.com/css?family=Roboto+Mono", "https://fonts.googleapis.com/css?family=Cantarell", "https://fonts.googleapis.com/css?family=Inconsolata", "https://fonts.googleapis.com/css?family=Gaegu" ); $font_display = $ref->multi_simul_fontdisplay($apilink,"fallback", false );
I receive an error in my php logs that say:

PHP Warning: count(): Parameter must be an array or an object that implements Countable in class.fontperformance.php on line 168

I have tried changing fallback to auto or optional and the I get the same error.

Can you tell me why this is ?
