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
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();
$var1 = "test";
session_register("var1");
?>
将放到后面即可
修改php.ini
upload_tmp_dir=d:/temp 或 /tmp
upload.php
====================================
if ($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;
}
?>
