iis php性能优化

// 示例：使用缓存
<?php
$cacheKey = 'data_key';
$cache = new Memcached();
$cache->addServer('localhost', 11211);

$data = $cache->get($cacheKey);
if (!$data) {
    $data = // 从数据库获取数据
    $cache->set($cacheKey, $data, 3600); // 缓存1小时
}
?>

<!-- 示例：调整IIS配置 -->
<configuration>
  <system.webServer>
    <handlers>
      <add name="php" path="*.php" verb="*" modules="FastCgiModule" scriptProcessor="C:\php\php-cgi.exe" resourceType="Unspecified" requireAccess="Script" />
    </handlers>
    <fastCgi>
      <application fullPath="C:\php\php-cgi.exe" maxInstances="4" idleTimeout="300" activityTimeout="30" />
    </fastCgi>
  </system.webServer>
</configuration>

// 示例：确保资源被正确释放
<?php
$db = new PDO('mysql:host=localhost;dbname=test', 'user', 'password');
try {
    $stmt = $db->prepare('SELECT * FROM users');
    $stmt->execute();
    while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
        // 处理数据
    }
} catch (PDOException $e) {
    echo 'Error: ' . $e->getMessage();
} finally {
    $db = null; // 释放数据库连接
}
?>
