PHP Copy function not working

问题

I'm trying to use copy function in php to copy an image from a url to my server.
The function opens the right folders on the server but the file is not in the last folder. its just empty.

Here's my piece of code:

$srcfile="http://domain.com/images2/2014/01/02/1.jpg";
$dstfile="/images/2014/01/02/1.jpg";
mkdir(dirname($dstfile), 0777, true);
copy($srcfile, $dstfile);

Any idea on why could this be?
Any help would be highly appreciated.

回答1:

Try this:

$srcfile="http://domain.com/images2/2014/01/02/1.jpg";
$dstfile=$_SERVER['DOCUMENT_ROOT'] . "/images/2014/01/02/1.jpg";
mkdir(dirname($dstfile), 0777, true);
copy($srcfile, $dstfile);

回答2:

$srcfile="http://domain.com/images2/2014/01/02/1.jpg";

I would suggest to determine the above file location from the copy function file. Write the jump location from there. e.g

$srcfile="../images2/2014/01/02/1.jpg";

Same goes with your destination file.

$dstfile="../images/2014/01/02/1.jpg";

The deeper the folder the more jump you need. e.g.

$dstfile="../../../images/2014/01/02/1.jpg";

Sometime writing full URL will not work because it will be like this :

$dstfile="http://domain.com/http://domain.com/images2/2014/01/02/1.jpg";

Which is just a repeating URL.
