Today's PHP ecosystem provides a couple better solutions for this now.
You can use Zephir to easily build PHP extensions in a PHP-like language. They provide a mechanism called custom optimizers that cleanly binds arbitrary C libraries or custom C code to your extension.
While it requires a little more work, it could (YMMV) result in near-C performance via native PHP calls, and upgrades your PHP-fu. You also might accidentally fall in love with Phalcon.
In my personal experience, pure Zephir actually harmed the performance of pure PHP for my task, so I would recommend it only if you want to leverage the power of existing C libs, or you have heavy workloads.
This Github comment provides a brief overview of why you should use the Zephir optimizer over an inline CBLOCK and how to structure your directories/files.
As of PHP 7.4, the Foreign Function Interface comes built-in. You can also install it as an extension for older versions of PHP.
The upside? You don't have to write your own PHP extension to use C code. The downside? Right now FFI performance doesn't really compare to actual C code. You can think of it more like a crutch than a batmobile.
If you care about high performance, try option 1.
