Are there any potential pitfalls or limitations when using PHP for web development compared to other languages?

One potential limitation of using PHP for web development is its performance compared to other languages like Node.js or Java. To improve PHP performance, you can utilize opcode caching extensions like OPcache to store precompiled script bytecode in memory, reducing the need to recompile scripts on each request.

// Enable OPcache in PHP
opcache_get_status();
