Performance Optimization in PHP

 Performance Optimization in PHP

PHP can be optimized to improve the performance of web applications. Techniques such as caching, code optimization, and database tuning can be used to speed up PHP applications.

Example:

php

// use caching to speed up page load times

$cache_key = "page_" . $_SERVER['REQUEST_URI'];

if ($cache->exists($cache_key)) {

    echo $cache->get($cache_key);

} else {

    $content = // generate page content

    $cache->set($cache_key, $content, 3600);

    echo $content;

}
