常見的幾個問題_PHP教程

1.配置php.ini，修改session.save_path
如：session.save_path = d:/developer/php/temp 或 /tmp
2.程式
1.php
session_start();
$var1 = "test";
session_register("var1");
?>
2.php
session_start();
echo $var1;
?>
首先運行1.php，然後運行2.php，頁面應該出現test
session "headers already sent" 錯誤問題
錯誤提示：Cannot send session cookie - headers already sent by ...
出現該錯誤是頁面中session_start();語句前存在輸出語句
如下例：

session_start();
$var1 = "test";
session_register("var1");
?>



將放到後面即可
檔案上傳
修改php.ini
upload_tmp_dir=d:/temp 或 /tmp
upload.php
