My recommendation is to search the 'ext' directory of the PHP source 
code.  It's a good place to find current, working examples.  The 
majority of PHP is actually a series of extensions.

You can also look at PECL extensions that have been around for a while. 
I maintain PECL sync, which has #ifdef macros that allow it to compile 
for both PHP 5 and 7 (not that PHP 5 support is relevant anymore).  I 
think PECL sync is a pretty good example since it is a fairly short, 
easily understood, real-world extension with no additional dependencies.
