file_put_contents: Failed to open stream, no such file or directory
提问by vaindil
I am trying to use dompdf to save a form to an easily-readable .pdf file, and my processing script is below. I am receiving the error Warning: file_put_contents(/files/grantapps/NAME0.pdf) [function.file-put-contents]: failed to open stream: No such file or directory in /home/username/public_html/subdir/apps/dompdf/filename.php on line 39. (Line 39 is the final line in my full script.) I don't know how to resolve this issue.
我正在尝试使用 dompdf 将表单保存为易于阅读的 .pdf 文件，我的处理脚本如下。我收到错误Warning: file_put_contents(/files/grantapps/NAME0.pdf) [function.file-put-contents]: failed to open stream: No such file or directory in /home/username/public_html/subdir/apps/dompdf/filename.php on line 39。（第 39 行是我完整脚本的最后一行。）我不知道如何解决这个问题。
allow_url_fopenis on, and I have tried all kinds of file paths, including the full directory (/home/username/public_html/subdir/files/grantapps/) and what's in the code below, but nothing worked.
allow_url_fopen已打开，并且我尝试了各种文件路径，包括完整目录 ( /home/username/public_html/subdir/files/grantapps/) 和下面代码中的内容，但没有任何效果。
require_once("dompdf_config.inc.php");
date_default_timezone_set('America/Detroit');
$html = 'code and whatnot is here';
$name = str_replace(" ", "", $_POST['form2name']);
$i = 0;
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
while(file_exists("files/grantapps/" . $name . $i . ".pdf")) {
$i++;
}
file_put_contents("files/grantapps/" . $name . $i . ".pdf", $dompdf->output());

There is definitly a problem with the destination folder path.
目标文件夹路径肯定有问题。
Your above error message says, it wants to put the contents to a file in the directory /files/grantapps/, which would be beyond your vhost, but somewhere in the system (see the leading absolute slash )
您上面的错误消息说，它想将内容放入目录中的文件中/files/grantapps/，这将超出您的vhost，但在系统中的某个地方（请参阅前导绝对斜杠）
You should double check:
你应该仔细检查：
- Is the directory
/home/username/public_html/files/grantapps/really present. - Contains your loop and your file_put_contents-Statement the absolute path
/home/username/public_html/files/grantapps/
- 目录是否
/home/username/public_html/files/grantapps/真的存在。 - 包含您的循环和您的 file_put_contents-Statement 绝对路径
/home/username/public_html/files/grantapps/

只需获取您要复制到的文件的确切网址 Ex->
http://www.test.com/test.txt (file to copy)
and pass the exact absolute folder path with filenamewhere do u want to write that file
并通过文件名传递确切的绝对文件夹路径，您要在哪里写入该文件

d:/xampp/htdocs/upload/test.txtand
1->如果你在 Windows 机器上然后
d:/xampp/htdocs/upload/test.txt和
2->if u r on linux machine then
/var/www/html/upload/test.txt
2->如果你在 linux 机器上，那么
/var/www/html/upload/test.txt
and u can get the docuement root by the PHP function->
你可以通过PHP函数获取文档根目录->
$_SERVER['DOCUMENT_ROOT']
