1.配置
php.ini，修改session.save_path如：session.save_path = d:/developer/php/temp 或 /tmp
2.程序
1.php
session_start();$var1 = "test";session_register("var1");?>
2.php
session_start();echo $var1;?>首先运行1.php，然后运行2.php，页面应该出现test session "headers already sent" 错误问题错误提示：Cannot send session cookie - headers already sent by ...
出现该错误是页面中session_start();语句前存在输出语句
如下例：
session_start();$var1 = "test";session_register("var1");?>将放到后面即可文件上载修改php.ini upload_tmp_dir=d:/temp 或 /tmp upload.php====================================PHP Upload if ($upload){$real_path = $userfile_name;if (file_exists($real_path)){unlink($real_path);}if (!@copy($userfile,$real_path))$upload_flag = false;else$upload_flag = true;}?>
