I'm using Ubuntu 16.04 and I'm trying the following code to write to a file.
<?php
$path = getcwd();
$fp = fopen($path . 'data.txt', 'w') or die("Can not open the file");
fwrite($fp, '1');
fwrite($fp, '23');
fclose($fp);
Initially the file permissions on data.txt was -rw-r--r-- and causing the following error:
fopen(data.txt): failed to open stream: Permission denied
So I changed file permissions to -rw-rw-rw-, but nothing is happening now.
It is neither writing to a file nor showing any error.
Can anybody please help me what has went wrong here?
Thanks in advance.
getcwd() does not contain the final slash. So you have to add it :
$fp = fopen($path . '/data.txt', 'w') or die("Can not open the file");
I run my webserver on windows (XAMPP Control Panel v3.2.2). I am creating files and folders like this:
use File;
...
$Path = app_path()
. '/Projects/'
. strtolower($Project->name)
. '/Schema/';
if (File::exists($Path)) {
$result = 1;
} else {
$result = File::makeDirectory($unitPath , '775', true);
$content = "the content is basically a whole controller";
$file = $Path . strtolower($Unit->name) . '.php';
$bytes_written = File::put($file, $content);
if ($bytes_written === false) {
return false;
}
}
The file which I create is a PHP controller.
The files and folders are created. However by using git bash I noticed that the permission is not set to 775 even though I have specified it in makeDirectory, same for the files.
If I try to execute an action from the created file (which is a controller), then I get:
ErrorException in
C:\xampp\htdocs\selenium\vendor\composer\ClassLoader.php line 440:
include(C:\xampp\htdocs\selenium): failed to open stream: Permission
denied
How can I solve this, other than running my webserver on linux instead of windows?
NOTE: Everything works fine on my computer at home, where I also run the webserver on windows. The only difference is that I am using Windows 10 64bit at home and Windows 7 64bit here at work.
UPDATE:
The ErrorException include(C:\xampp\htdocs\selenium): failed to open stream: Permission denied dissapeared after executing composer update. But the question how I can create a file/folders with specific permissions persists.
UPDATE 2:
After creating a new file the ErrorException appears again...
I'm working on implementing Safari Push Notification service for my website. I've been following the tutorial made by Apple which can be found here. And we have to create a package to serve push notifications and Apple provides a companion php file that helps to create the package.
Now I've downloaded the php file and tried running it, but it always throws a warning saying "Failed to open stream: No such file or directory".
Full Log:

PS: I do have a directory named pushPackage.raw that contains a folder called icon.iconset which has a set of 6 png images. So I have no idea why it says "No such file is present".

Another thing, this php script does create a package at the specified location (D:/Users/Mike/Desktop), but without the contents present in the pushPackage.raw directory.
Please help me resolve this issue. Thank you so much!
You need to run createPushPackage.php from the folder with Safari-Push-Notifications package (in your case D:\..\Downloads\Safari-Push-Notifications-master\) because code copy("pushPackage.raw/$raw_file", "$package_dir/$raw_file"); use relative path to assets files.
Add some explanation for relative paths:
bash$ pwd
/var/www/test # we inside /var/www/
bash$ ls -la # there are 2 files
-rw-r--r-- 1 alexanderpolomodov wheel 48 Mar 7 15:07 test.php
-rw-r--r-- 1 alexanderpolomodov wheel 15 Mar 7 15:08 test.txt
# test.php consist from one string
# var_dump(file_get_contents('test.txt'));
bash$ php test.php # run this script
string(15) "test filepaths"
bash$ cd ..
# when we run this command from another folder we get error
bash$ php test/test.php
Warning: file_get_contents(test.txt): failed to open stream: No such file or directory in /private/var/www/test/test.php on line 3

I've recently migrated linux servers.
I'm currently getting this error when trying to upload an image using Imagick from a form.
Warning: fopen(/home/user/public/website.com/public/images/users/current/thumb/username.jpg): failed to open stream: Permission denied in /home/user/public/website.com/public/inc/functions/functions.php on line 864
The code that is run resides in a function:
try{
$im = new Imagick($image['tmp_name']);
if($im_w != 'O' && $im_h != 'O'){
$im->cropThumbnailImage($im_w,$im_h);
}
$fp = fopen($path, 'w'); //the line that is causing the error to occur. line 864.
$im->writeImageFile($fp);
return 1;
}
catch(Exception $e)
{
echo $e->getMessage();
}
I've had a look through various PHP/Linux fixes for permissions, The /images/ directory and subdirectories currently have permission: 755
Can anyone help me with a solution. Comment if you need to know anything else.
Thanks in advance.
Simply entered the command into my linux command line:
sudo chmod -R 777 /home/username/public/website.com/public/x_images/
Here's my setup. I've got a linux box running Apache and PHP. I have a folder mounted on my linux box that points to a directory on my windows server where my HTML files are stored. My virtualhosts file points to the mounted folder, so Apache is getting the files from the Windows share.
I'm having some issues with fopen. When I run this:
<?php
echo 'cwd is: ', getcwd(), "<br />\n";
echo 'target should be: ', getcwd(), "/data.txt <br />\n";
echo 'file already exists: ', file_exists('data.txt') ? 'yes':'no', "<br />\n";
$file = fopen("data.txt", "a");
if ( !$file ) {
die('fopen failed');
}
$c = fwrite($file, "\n$name,$lastname,$email");
fclose($file);
echo $c, ' bytes written';
?>
I get the following back:
cwd is: /home/brian/website/googlecalendar/html
target should be: /home/brian/website/googlecalendar/html/data.txt
file already exists: no
Warning: fopen(data.txt): failed to open stream: Permission denied in /home/brian/website/googlecalendar/html/testfopen.php on line 7 fopen failed
On Windows, I've checked the permissions on the "html" folder, and everything is set to allow everyone to write. I'm not sure what else I need to change. It should work, right?
Hi
Try,Change the sub directory and files to be in the group "www"
