I have an issue that I cannot create any files using fopen.

I am using this as a test:

<?php
$myfile = fopen("testfile.txt", "w")
?>

and this error is output in NewRelic (and no testfile.txt is not created):

fopen(testfile.txt): failed to open stream: Permission denied

drzip28288 它几乎是一样的。问题的根源是相同的:写入文件或目录(特别是当前目录)的权限不足。因此,检查两者的权限并使用chmod修复它们,例如chmod775/path/to/the/directory&&chmod644/path/to/the/directory/testfile.txt。毫无疑问,这是一个FAQ。

这是因为你没有权利打开它。
确保你有​​权写。 如果在linux上你可以使用chmod()来设置文件的右边。</ p>

It's because you don't have the right to open it. Make sure you have the right to write. If on linux you can use chmod() to set the the right of the file.

尝试在public_html中创建页面时,错误无法打开流权限被拒绝

<div class="post-text" itemprop="text"> <p>I am trying to run a script which creates pages and saves them to the server but am getting a permission error on one of the files that is in the public_html directory.</p> <p>So 2 pages are created in the "pages" directory which is chmod to 0777 and they are created fine. The 3rd page is created in the "public_html" directory which fails with you do not have permission. The only way i have found to fix this is to chmod the "public_html" directory to 0770 which then everything works but i have been strongly advised by the hosting company not to do this bevause of the security risk.</p> <p>So my question is, Is there any otherway to achieve this goal? Looking into it a bit it looks like i need to give the script "user" priviliges might work but this is beyond my knowledge at the moment. I`m not even sure what the script is running as at the moment, I would guess "group" as chmoding the public_html to 0770 allows "group"</p> <p>My setup is: vps server running centos CENTOS 6.7 x86_64</p> <p>php 5, dso, Apache suEXEC on</p> <p>simplified Code i am using is:</p> <pre><code>$page_path = "/home/username/public_html/"; $loop[Html_Name] = "test.html"; $new_page_file = "test.html"; $fp = fopen($page_path.$loop[Html_Name], "w"); fwrite($fp, $new_page_file); fclose($fp); chmod($page_path.$loop[Html_Name], 0666); </code></pre> <p>Many thanks in advance.</p> </div>
