PHP Configuration and Performance Optimization on Kangle Server

PHP Configuration

Locate the php.ini File

On a Kangle server, the PHP configuration file is usually located at /3rd/php54/php.ini. Editing this file allows you to modify PHP settings to suit your website's needs.

Adjust Memory Limit

memory_limit = 256M

By adjusting memory_limit, you can set the maximum memory a PHP script is allowed to use, preventing errors caused by insufficient memory.

Enable Error Logging

error_reporting = E_ALL
log_errors = On
error_log = /your/error/log/path

Enabling error logging helps detect PHP runtime issues promptly and makes troubleshooting easier.

Adjust File Upload Limits

upload_max_filesize = 20M
post_max_size = 25M

Adjust file upload and POST data size limits according to your website's requirements to improve file upload efficiency and stability.

PHP Optimization

Enable OPcache

extension = opcache.so
opcache.enable = 1
opcache.enable_cli = 1
opcache.memory_consumption = 128
opcache.interned_strings_buffer = 8
opcache.max_accelerated_files = 4000
opcache.revalidate_freq = 60

OPcache is a built-in PHP extension that caches PHP scripts, reducing parsing and compilation time, and significantly improving website response speed.

Enable Caching Mechanism

$memcached = new Memcached();
$memcached->addServer('localhost', 11211);

Using caching mechanisms such as Memcached can reduce database queries, speed up page load times, and improve overall performance.

Control Script Execution Time

Long-running PHP scripts can consume excessive server resources. By setting max_execution_time, you can limit script execution time and prevent server overload.

Conclusion

Proper configuration and optimization of PHP can significantly improve website performance and security on a Kangle server. By adjusting memory and upload limits, enabling OPcache and caching mechanisms, and controlling script execution time, your website will run more efficiently and reliably.
