PHP fopen($file, "w") permission denied

Question

I have a problem with a php script on my webserver (Apache/2.4.10 on Raspbian), I can't generate a new file on it. I have tried chmod 777 (which is really bad practice) and it still didn't work. I have been struggling with this for a few days and even after extensive research I couldn't find a solution to this problem. Below is my code and the error messages generated by it:

<?php
ini_set('display_errors',1);
error_reporting(E_ALL);
$newwish = fopen("newfile.txt", "w+");
$txt = "LALALA";
fwrite($newwish, $txt);
fclose($newwish);
?>

Warning: fopen(newfile.txt): failed to open stream: Permission denied in /var/www/html/handlers/wish.php on line 4

Warning: fwrite() expects parameter 1 to be resource, boolean given in /var/www/html/handlers/wish.php on line 6

Warning: fclose() expects parameter 1 to be resource, boolean given in /var/www/html/handlers/wish.php on line 7

@Chris apache's www folder, recursively, after I made sure that it is owned by the user under which apache is running — technical_difficulty, Apr 28 '16 at 22:27
That seems like overkill. If you do `ls -la` in the folder your PHP file is in what output do you get? — Chris, Apr 28 '16 at 22:28

From the same directory, can you try `chmod 777 .` and see if that works? — Chris, Apr 28 '16 at 22:33
@Chris You were right, I didn't chmod it correctly, now it works, but what security risks does 777ing a file that is available to the internet introduce? — technical_difficulty, Apr 28 '16 at 22:37
Provided you only `chmod` what you need, the risk is very low. It would still be more secure to `chown` the group to `www-data` and set the directory permissions to 775. — Chris, Apr 28 '16 at 22:39

@Vic The error I encountered was a denial of permission wheras the question you mentioned is about php not finding a directory — technical_difficulty, Apr 30 '16 at 11:41
@boban, the answers to the question I pointed to includes problems of permissions and how to solve them — Vic Seedoubleyew, Apr 30 '16 at 11:41

I tried your script in the CLI and works well.

Try to make www-data the owner of the folder and the content that contain the script:

chown -R www-data:www-data phpscript/

and then give to the php script file permissions:

chmod 644 index.php
