Monitor and Debug Performance Issues:

Regularly monitor and debug PHP applications to identify and address performance bottlenecks. Consider the following techniques:

• Profiling: Use tools like Xdebug or PHP’s built-in profiler to analyze execution times and memory usage.
• Database Query Analysis: Analyze slow database queries using tools like EXPLAIN to identify inefficient query execution plans.
• Cache Hit Ratio: Monitor cache hit ratio to ensure effective utilization of caching mechanisms and optimize cache configuration as needed.
