How do I check if I have write permissions in the current path

Question

in php how do I determine whether or not I can create a file in the same path as the script trying to create a file

Answer 1

Use is_writable PHP function, documentation and example source code of this you can find at http://pl2.php.net/manual/en/function.is-writable.php

Answer 2

Have you tries the is_writable() function ?

Documentation http://www.php.net/manual/en/function.is-writable.php

Example:

$filename = 'test.txt';
if (is_writable($filename)) {
    echo 'The file is writable';
} else {
    echo 'The file is not writable';
}

Answer 3

The is_writable function is good stuff. However, the OP asked about creating a file in the same directory as the script. Blatantly stealing from vlad b, do this:

$filename = __DIR__ . '/test.txt';
if (is_writable($filename)) {
    echo 'The file is writable';
} else {
    echo 'The file is not writable';
}

See the php manual for predefined constants for the details on __DIR__. Without it, you're going to create a file in the current working directory, which is probably more or less undefined for your purposes.
