提问by Fahad Khan
I am Using mPDFto generate pdf from an html.
我正在使用mPDF从 html 生成 pdf。
On my localhost the pdf is generated to the located directory successfully. But not on Server, although I have open the permissions of that directory.
在我的本地主机上，pdf 已成功生成到找到的目录中。但不是在服务器上，虽然我已经打开了那个目录的权限。
chmod -R 0777 /mydirectory
Found this commentfrom an answer and changed fopen($file_out,'wb');to fopen($file_out,'w+');in mpdf.php
从答案中找到 此评论并更改fopen($file_out,'wb');为fopen($file_out,'w+');mpdf.php
But no success.
但没有成功。
Thanks for any help.
谢谢你的帮助。

Try not to modify the source. Instead, revert back to fopen($file_out,'wb');and make sure that folder permissions are set to 0777, like you did.
尽量不要修改源。相反，恢复到fopen($file_out,'wb');并确保文件夹权限设置为0777，就像您所做的那样。
Also, check if you're using the absolute pathin order to write to a file, rather than using relative paths or even worse, URL.
此外，请检查您是否使用绝对路径来写入文件，而不是使用相对路径或更糟糕的是 URL。
So,
所以，
$file = "/var/www/html/mywebsite/mypdfs/myfile.pdf";
$file = "/var/www/html/mywebsite/mypdfs/myfile.pdf";
and try if it works.
并尝试它是否有效。
Good luck!
祝你好运！
