and post_max_size
-
Purpose: Determines the maximum file upload and POST data size.
-
Recommended Value:
-
Adjust based on your application’s needs (e.g., 64M for file uploads).
-
-
Configuration:

-
-
Configuration:
realpath_cache_size = 128K
8. session.cache_limiter
-
Purpose: Determines caching behavior for sessions.

Recommended Value:
-
nocache
for dynamic content. -
public
for static session data.
-
-
Configuration:
session.cache_limiter = nocache
🛡️ Best Practices for PHP Performance Optimization
-
Enable Opcode Caching:
-
Use PHP’s built-in OPcache or an external accelerator like APCu.
-
-
Monitor Error Logs:
-
Regularly check logs for bottlenecks and deprecated features.
-
-
Upgrade PHP Version:
-
Use the latest stable PHP version for improved performance and security.
-
-
Limit Resource-Intensive Operations:

Avoid excessive loops and optimize database queries.
-
-
Optimize Database Connections:
-
Use persistent connections and proper indexing.
-
🤔 Troubleshooting Common Issues
-
Settings Not Taking Effect:
-
Ensure changes are saved and the web server is restarted.
-
-
Memory Exhaustion Errors:
-
Increase
memory_limit
or optimize scripts.
-
-
Upload Failures:
-
Adjust
upload_max_filesize
andpost_max_size
.
