=== 執行PHP時顯示原始碼的錯誤 === 確認伺服器是否能執行 PHP * 驗證方式: ** 網頁伺服器放置寫了 [http://php.net/manual/en/function.phpinfo.php phpinfo] 的 PHP 檔案,看是否可以顯示結果。使用後建議移除該檔案,避免對外揭露伺服器環境資訊。或 ** {{kbd | key = <nowiki>php -v</nowiki>}} 如果可以顯示 PHP 版本資訊,代表有安裝 PHP 成功。 * 解決方式: ** 不能執行 PHP 的話,需要檢查 [http://php.net/manual/en/install.php 安裝 PHP] 步驟。 如果 PHP 使用 short tag 語法撰寫,但是沒有啟用 short_open_tag ,會造成顯示原始碼的錯誤。 * 驗證方式: ** 輸入指令 {{kbd | key = <nowiki>php -i | grep short_open_tag</nowiki>}} 確認結果為 short_open_tag = Off * 解決方式: ** 法1: 啟用 short_open_tag (1) php.ini 檔案 需要開啟 short_open_tag = Off -> On (2) 重新啟動網頁伺服器服務,讓 php.ini 修改生效 (3) 驗證 short_open_tag = On ** 法2: 不啟用 short_open_tag,將多個 PHP 檔案的 {{kbd | key=<nowiki><? </nowiki>}} 改成 {{kbd | key=<nowiki><?php </nowiki>}}。 (1) 使用支援 [[Regular expression]] 的文字編輯軟體、(2) 搜尋 {{kbd | key=<nowiki><\?\s</nowiki>}} 取代為 {{kbd | key=<nowiki><\?php </nowiki>}} 。請注意取代部分結尾有一個空白。詳見 [[Batch remove PHP short tags]]
