any tips教程, ideas or solutions welcome :)
before I dig into the PHP (about which I know little or nothing) :-(

 

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at E:phpcodeadmin.php:1) in E:phpcodelogolistadminlogo.php on line 2

上网搜了一下，有人说是因为在session_start(); 语句之前有其他的html代码，但是我的session_start(); 已经在做前面了。
还有的说是因为没有设置session 保存路径，需要修改php.ini中的session.save_path = "C:/phpsession" [后边的路径自己设置，并且要保证存在。php.ini 文件一般应位于系统盘/Windows 目录下面]

但是我做如上设置之后还是会有这个提示。后来经过反复测试，终于解决问题。
解决办法：
修改php.ini中的session.auto_start = 0 为 session.auto_start = 1

Warning: Cannot send session cache limiter - headers already sent (output started at /home/alltom/public_html/flame/template.inc.php:1) in /home/alltom/public_html/flame/lib.inc.php on line 550

Whats wrong with that? I mean why am i getting it??

Line 547 to 550 in lib.inc.php:

session_set_save_handler('sess_open', '', 'sess_read', 'sess_write', 'sess_destroy', 'sess_gc');
session_name('s');
session_name('s');
session_start();

Im having problems with session_start() through out the site, any help???

看个实例

<?php
session_start();

echo 'Welcome to page #1';

$_SESSION['favcolor'] = 'green';
$_SESSION['animal']   = 'cat';
$_SESSION['time']     = time();

// Works if session cookie was accepted
echo '<br /><a href="page2.php">page 2</a>';

// Or maybe pass along the session id, if needed
echo '<br /><a href="page2.php?' . SID . '">page 2</a>';
?>

并且<? 前面不能有任何字符
但还有几种我没试，他们是
1.php.ini中的output_buffering=off 改成output_buffering=4096
2.php.ini中的session.save_path是否设置好了
3.pgp.ini中的session.auto_start = 0 改成session.auto_start = 1
