實例一：
- //ob緩衝
- $filename="aa.html";
- ob_start();
- if(file_exists($filename))
- {
- echo "緩存頁面";
- echo "</br>";
- echo file_get_contents($filename);
- }
- else
- {
- echo "這是要緩存到頁面的內容";
- $content=ob_get_contents();
- $fb=fopen($filename,'w');
- fwrite($fb,$content);
- fclose($fb);
- }
- <?php
- $filename="aa2.html";
- if(file_exists($filename))
- {
- echo "緩存中讀取的";
- $files=file_get_contents($filename);
- echo $files;die;
- }
- else
- {
- $dsn = "mysql:host=127.0.0.1;dbname=數據庫";
- $db = new PDO($dsn, '數據庫賬號','數據庫密碼');
- $rs = $db->query("SELECT * FROM ecs_users");
- $rs->setFetchMode(PDO::FETCH_ASSOC);
- $arr = $rs->fetchAll();
- //首先要開啓緩衝
- ob_start();
- }
- ?>
