How to use Unlink() function

Question

I'm trying to use PHP unlink() function to delete away the specific document in the folder. That particular folder has already been assigned to full rights to the IIS user.

Code:

$Path = './doc/stuffs/sample.docx';
if (unlink($Path)) {    
    echo "success";
} else {
    echo "fail";    
}

It keep return fail. The sample.docx does reside on that particular path. Kindly advise.

Answer 1

I found this information in the comments of the function unlink()

Under Windows System and Apache, denied access to file is an usual error to unlink file. To delete file you must to change the file's owner. An example:

chown($tempDirectory . '/' . $fileName, 666); //Insert an Invalid UserId to set to Nobody Owern; 666 is my standard for "Nobody" 
unlink($tempDirectory . '/' . $fileName); 

So try something like this:

$path = './doc/stuffs/sample.docx';

chown($path, 666);

if (unlink($path)) {
    echo 'success';
} else {
    echo 'fail';
}

EDIT 1

Try to use this in the path:

$path = '.'
         . DIRECTORY_SEPARATOR . 'doc'
         . DIRECTORY_SEPARATOR . 'stuffs'
         . DIRECTORY_SEPARATOR . 'sample.docx';

Answer 2

Try this:

$Path = './doc/stuffs/sample.docx';
if (file_exists($Path)){
    if (unlink($Path)) {   
        echo "success";
    } else {
        echo "fail";    
    }   
} else {
    echo "file does not exist";
}

If you get file does not exist, you have the wrong path. If not, it may be a permissions issue.
