當我的網站上傳到服務器時，我遇到了一個問題。在本地主機上它正常工作。Dir使用imagepng時受到限制PHP GD
基本上我的功能是更新圖像與圖像，然後存儲在新的文件名（圖像）。
php腳本：
function updateimage()

運行時其沒有動靜，然後我檢查文件夾可寫或不涉及這樣
Dir: /home/kagasiac/public_html\simtag\images
File: /home/kagasiac/public_html\simtag\images/44801aed40d934e6b15c89a2363cc9abtag2.png
dir Restricted
File does not exist
任何想法？
偏離主題，但我敢打賭你會對[使用PHP切換]感興趣（http://php.net/manual/en/control-structures.switch.php） – larsAnders
而不是使用DOCUMENT_ROOT您可能需要指定從public_html開始的文件結構。您的網絡服務器可能不允許引用DOCUMENT_ROOT目錄。此外，您已將文件路徑中的\和/混淆。 \是一個轉義字符，因此您可能需要指定兩次\\ simtag \\ images – Brett
謝謝@brett我改爲$ path =「\\ public_html \\ simtag \\ images \\」。$ ip。「tag2。 PNG「;但文件保存在名稱爲\ public_html \ simtag \ images \ 8973ee1cd414efaff7d0e71b138609a0tag2.png的根文件夾中不在文件夾圖像中。 – reefman
