How do I check if a directory is writeable in PHP?

Question

Does anyone know how I can check to see if a directory is writeable in PHP?

The function is_writable doesn\'t work for folders.

Edit: It doe

Answer 1

this is how I do it:

create a file with file_put_contents() and check the return value, if it is positive (number of written in Bytes) then you can go ahead and do what you have to do, if it is FALSE then it is not writable

$is_writable = file_put_contents('directory/dummy.txt', "hello");

if ($is_writable > 0) echo "yes directory it is writable";

else echo  "NO directory it is not writable";

then you can delete the dummy file by using unlink()

unlink('directory/dummy.txt');
