I am using this function. is_file and is_writable return true, but when I true to unlink, it gives an error. This is on windows server.
if(is_file($fileToDelete)) {
if(is_writable($fileToDelete)) {
unlink($fileToDelete);
}
}
The file is a PDF document, which I have open. I thought is_writable would return false in this case, but it doesn't.
So how can I tell if a file can be deleted or not?
Thank you
What about doing it the other way around? Just try to delete the file and check whether it is really gone?
@unlink($fileToDelete);
if(is_file($fileToDelete)) {
// file was locked (or permissions error)
}
Not sure whether this is workable in your specific case though, but judging by the code in your question this should be what you want.
