PHP Fopen() Error: Failed to Open Stream: Permission Denied

PHP fopen() Error: failed to open stream: Permission denied

You may need to change the permissions as an administrator. Open up terminal on your Mac and then open the directory that markers.xml is located in. Then type:

sudo chmod 777 markers.xml

You may be prompted for a password. Also, it could be the directories that don't allow full access. I'm not familiar with WordPress, so you may have to change the permission of each directory moving upward to the mysite directory.

fopen() fails to open stream: permission denied, yet permissions should be valid

Check if the user that PHP runs under have "X" permission on every directory of the file path.

It will need it to access the file

If your file is: /path/to/test-in.txt
You should have X permission on:

• /path
• /path/to

and read permission on /path/to/test-in.txt

PHP function.fopen failed to open stream: Permission denied

Obviously PHP doesn't have write access to the file.
This being on Ubuntu PHP runs as the same user as Apache, so make sure the file is writable by the www-data group.

user@host:/path/to/your/file# chgrp www-data yourfile.txt
user@host:/path/to/your/file# chmod g+w yourfile.txt

Failed to open stream PHP fopen() not working

The reason why it is throwing that error is, php need to have write permissions on that folder, Try to give it write permissions and try again

Why is PHP unable to open a stream, permission denied using mode w+ fopen?

You're passing __DIR__ as the "sink" where to write the file. That's a directory. You can't write data to a directory like it was a file. Try using the name of a file.

$downloadClient = new Client(['base_uri' => 'https://vendor/region']);
$downloadResponse = $downloadClient->request('GET','endpoint/file_url.txt',
      ['sink' => "file_url.txt"]);

PHP - fopen: failed to open stream: Permission denied

because you open a directory , fopen function just open file. your code is fill with error , just Refer to the following:

<?php  

//make directory
$host = "aa";         //define $host variable
$directoryForServer = "upload";
$directoryForClient = $directoryForServer."/".$host."";
@mkdir($directoryForClient);  

$splitePath = explode("/", $directoryForClient);
$folderPath1 = $directoryForClient;

for($x = 1; $x <= (count($splitePath)-1) ; $x++)
{
    $folderPath1 = $folderPath1."/".$splitePath[$x];
    echo "<br>".$folderPath1." - successfully created<br>2";
    @mkdir($folderPath1);
}

writefile($folderPath1);

function writefile($dir)
{
 if( is_dir($dir)){
    echo $dir;
    $myFile = fopen("upload/aa.txt","w");
    if($myFile)
    {
        $returned_content = "hello world";  //define variable and his content before write to file.
        fwrite($myFile, $returned_content);
    }
    fclose($myFile);
  }
}
