dn001
示例程序:test_session.php3

<?php require( "session.inc.php3");
require("cookie.inc.php3");
?>
<?php
session_checkid( 20 ); //20分钟后session失效
//下面你需要设置mysql的连接参数
mysql_connect(’localhost’,’user’,’pass’) or Die("can’t connect to db!");;;
?>;;
<!DOCTYPE HTML PUBLIC "//W3C//DTD HTML 3.2 Final//EN">
<html>;;
<head>
<title>Session/Cookie-测试</title>;;
</head>;;
<body>
<h2>This Page should show how to handle the "session.inc.php3" library</h2>
<h3>We will use a mask with a record showing routine</h3>;;
<?php
if( $show ) {;;
if( session_read() ) {;;
$username = $session[username];;;
$userpass = $session[userpass];;;
echo "<P>session[username]:$username
session[userpass]:$userpass"
}
};;
else{
$session[username]="yourid"
$session[userpass]="12345"
if( !session_write() ) {;;
print $sess_error;;;
}else{
echo "<p>session[username]被设置成:$session[username]
" ;
echo "session[userpass]被设置成:$session[userpass]
" ;
echo "<a href=’$PATH_INFO?show=1’>测试一下SESSION的作用</a>" ;
}
}
?>

</body>;;
</html>;;;
