一个简单的 session 使用
<?
session_start();
//注册一个session变量
session_register('counter');
//增加计数器
$counter++;
echo "You have visited this page $counter times! Don't you have anything else to do, you bum?!"; //session_start();
//session_register('count');
//$count++;
//echo "<P>You've been here $count times.</p>";
?> session_start -- Initialize session data
bool session_start ( void )
session_start() creates a session or resumes the current one based on the current session id that's being passed via a request, such as GET, POST, or a cookie.
This function always returns TRUE.
注: If you are using cookie-based sessions, you must call session_start() before anything is outputted to the browser. session_register -- Register one or more global variables with the current session
bool session_register ( mixed name [, mixed ...] )
session_register() accepts a variable number of arguments, any of which can be either a string holding the name of a variable or an array consisting of variable names or other arrays. For each name, session_register() registers the global variable with that name in the current session. 结果
调试警告 - Unknown(): Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. 声明：O:\php\Apache Group\Apache2\htdocs\t1\t2.php 行 6 - Undefined variable: counter 访问的时候一片空白，源码成了这样 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<META http-equiv=Content-Type content="text/html; charset=gb2312"></HEAD>
<BODY></BODY></HTML> 不知道是不是由于我修改了PHP.INI？或者ZEND自己又一套PHP，两个乱七八糟的
错误应用程序 Apache.exe，版本 2.0.54.0，错误模块 ntdll.dll，版本 5.1.2600.1106，错误地址 0x000267cd。 反正我决定彻底的重新安装一遍。 ZEND不再自行安装新的PHP，直接使用原安装的。
