Question

I wanna copy some doc files from a link. But, sometimes there’s link that we don’t have permission to access or the link that expired. For the link that we don’t have permission, is there a solution?
and I wanna change the error message when it happen, the error message that I get is :

Warning: copy(http://www-cgi.cs.cmu.edu/afs/cs.cmu.edu/Web/People/ngm/15-721/summaries/12.pdf) [function.copy]: failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden in D:\AppServ\www\academicopter\functionWrapper.php on line 33

I’ve tried to change the error message with (or die ('CANNOT COPY')) the code below :

copy($Link, $savePath . basename($Link)) or die ('CANNOT COPY');

but, the error message still same warning ..... how to change it? thank you 🙂

Answer 1

You can muffle the warning using the @ operator. Note that it would still run any custom error handler you may have configured.

if (false === @copy(...)) {
    // copy failed
}

AFAIK there’s no other way to get rid of the warning unless you use cURL to copy the file instead.

Edit

You could also use get_headers($url) and look for HTTP/x.x 403. It’s one more request and personally I would save myself the trouble 🙂
