php83-gd: imagefontwidth and imagefontheight fail on valid GDFont

[jonaskohl (Jonas Kohl)]

When using imagefontwidth($font); with a font loaded using imageloadfont(...), the call fails with the following exception:

Uncaught TypeError: imagefontwidth(): Argument #1 ($font) must be of type GdFont|int, GdFont given

This is not reproducible on non macOS systems, so it seems to be a problem with this port.

I have attached a simple MVP that reproduces this problem (at least on my Mac). Just run sample.php via php-cli.

Just run sample.php via php-cli.

I get:

The following ports are currently installed:
  php83 @8.3.1_0+libedit (active)

I get the following output:

I can't explain it. The error message seems to be saying that you must supply imagefontwidth with either a GdFont or an int and that you have supplied a GdFont so I don't know what the problem is.

What we do at MacPorts is make other people's software easy to install on a Mac, but we are not experts in that software or how to fix its code if it doesn't work correctly, so I think you should report it to the developers of PHP.

[ryandesign (Ryan Carsten Schmidt)]

One thing you could try is check if you have any other active php83 modules:

port installed active and name:^php83-

If so, try deactivating them and see if the problem disappears. If it does, isolate which of the other modules is causing the problem.

[jonaskohl (Jonas Kohl)]

I've now deactivated every php83 module except GD (and the core PHP port itself of course), but the problem still occurs. I will now report this bug over at php-src. But as I said, I could not reproduce this on non-mac systems. For example, it worked just fine inside an Ubuntu Docker container.

Thanks, I see you reported it here: ​https://github.com/php/php-src/issues/13082
