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;

}

?>
