用於從mysql表中提取數據的php腳本的緩存選項

我想知道用什麼函數來緩存所拉取的數據並在15-30分鐘後才刷新它。用於從mysql表中提取數據的php腳本的緩存選項

這裏是從mysql數據到網站的PHP腳本。

<?php 
include('mysql_connection.php'); 

$c = mysqlConnect(); 

$locale = $_GET['locale']; 
$last_bulletins_id = $_GET['bulletins_id']; 

sendQuery ("set character_set_results='utf8'"); 
sendQuery ("set collation_connection='utf8_general_ci'"); 

if(strcmp($locale,"en") != 0) 
$locale = "en"; 
$result = sendQuery(" 
SELECT bulletins.id, posted_date, message, name 
FROM bulletins 
LEFT JOIN players ON (bulletins.player_id = players.user_id) 
WHERE bulletins.id > ".$last_bulletins_id." and locale = '".$locale."' 
ORDER BY bulletins.id DESC 
LIMIT 10"); 
echo '<table width=\"100%\">'; 
while($row = mysql_fetch_array($result, MYSQL_NUM)) 
{ 
    echo '<tr><td width=\"100%\"><b>Date: </b>'.$row[1].'</td></tr>'; 
    echo '<tr><td width=\"100%\"><b>Author: </b>'.$row[3].'</td></tr>'; 
    echo '<tr><td width=\"100%\">'.nl2br($row[2]).'</td></tr>'; 
    echo '<tr><td width=\"100%\"><hr style="height: 2px; border: none; background: #515151;"></td></tr>'; 
} 
echo '</table>';  

mysqlClose($c);
