permission denied - php unlink
permissions, php, unlink
Solution
You (as in the process that runs `b.php`, either you through `CLI` or a webserver) need write access to the directory in which the files are located. You are updating the directory content, so access to the file is not enough.
Note that if you use the PHP `chmod()` function to set the mode of a file or folder to `777` you should use `0777` to make sure the number is correctly interpreted as an octal number.
Problem
I have two files: b.php and test.txt ``` <?php $b = "test.txt"; unlink($b); ?> ``` and the error is: Warning: unlink(test.txt) [function.unlink]: Permission denied why? b.php and test.txt is 777 and the same group/login if I set 777 on the parent directory I can execute unlink but i have to set 777 and back to 755?
