$qid=mysql_query($qry,$SESS_DBH);
return $qid;
}
function sess_gc($maxlifetime){
global $SESS_DBH;
$qry="delete from db_session where expiry < ".time();
$qid=mysql_query($qry,$SESS_DBH);
return mysql_affected_rows($SESS_DBH);
}
session_module_name();
session_set_save_handler("sess_open","sess_close","sess_read","sess_write","sess_destroy","sess_gc");
?>
4.建立测试文件。
在使用之前必须引用刚刚建立的session_mysql.php文件。
session_test.php
PHP代码:
<?php
include ("session_mysql.php");
session_start();
$_SESSION['abc']= "A: I will be back!";
$_SESSION['meto']= "B: Me too ";
$_SESSION['name']= "louis ";
echo "<a href="get_session_test.php">click me</a>";
?>
get_session_test.php
<?php
include ("session_mysql.php");
session_start();
echo $_SESSION['abc'];
echo "<br>";
echo $_SESSION['meto'];
echo "<br>";
echo $_SESSION['name'];
$_SESSION['wq']="12e";
echo "<br><a href="get_session_test2.php">click again</a>";
?>
get_session_test2.php
<?php
include ("session_mysql.php");
session_start();
echo $_SESSION['abc'];
echo "<br>";
echo $_SESSION['meto'];
echo "<br>";
echo $_SESSION['name'];
echo "<br>";
echo $_SESSION['wq'];
//session_destroy();//用来销毁所有session的函数。
?>
