How can I optimize my server's PHP configuration for better performance?
Asked on Jan 19, 2026
Answer
Optimizing your server's PHP configuration can significantly enhance performance by adjusting settings to better utilize resources and improve execution efficiency. Focus on key PHP directives and caching mechanisms to achieve this.
; Enable OPcache for performance
opcache.enable=1
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000
opcache.revalidate_freq=2
; Adjust memory limit
memory_limit=256M
; Set maximum execution time
max_execution_time=30
; Optimize error logging
log_errors=On
error_reporting=E_ALL & ~E_DEPRECATED & ~E_STRICT
Additional Comment:
- Enable OPcache to cache precompiled script bytecode, reducing load times.
- Adjust `memory_limit` based on your application's needs to prevent memory exhaustion.
- Set `max_execution_time` to a reasonable limit to avoid long-running scripts.
- Use error logging to catch and resolve issues without displaying errors to users.
- Regularly update PHP to the latest stable version for performance improvements and security patches.
- Consider using a PHP-FPM setup for better resource management and concurrency handling.
