Fix PHP 8 Syntax Issue

I’m running a site on Apache with PHP 8.x and have hit a wall with what appears to be a pure code-syntax problem. The server itself is behaving, but one or more scripts now throw fatal errors after the recent version bump. I need someone who can drop in, identify the faulty lines, and patch them so everything runs cleanly again without breaking existing functionality.

You should already feel comfortable combing through modern PHP 8 features (typed properties, union types, match expressions, etc.) and spotting the classic gotchas that trip an upgrade. When you reply, focus on the relevant experience you have fixing syntax or backward-compatibility issues; no long proposals—just a quick note on similar fixes you’ve completed is perfect.

Deliverables I expect:
• Corrected PHP files with the syntax errors resolved
• A brief summary of what was changed and why, so I can avoid the same pitfalls next time

If you can tackle this promptly, I’m ready to get started right away.
