PHP file root path problem after new install on vista

ed100

Have just installed wamp on vista, which works, except when php accesses files from a root path, eg, this fails:

$source = imagecreatefromjpeg("/Music/db/sleeves/767-1.jpg");

with error

PHP Warning: imagecreatefromjpeg(/Music/db/sleeves/767-1.jpg) [<a href='function.imagecreatefromjpeg'>function.imagecreatefromjpeg</a>]: failed to open stream: No such file or directory in C:\wamp\www\Music\db\thumb.php on line 10

however, this works perfectly

$source = imagecreatefromjpeg("C:/wamp/www/Music/db/sleeves/767-1.jpg");

but I don't want to go through all my scripts where I have root links. Everything previously worked fine on a wamp / xp install.

same problem happens with any function that accesses a file.

Any suggestions please?

Thanks,
Ed.

I'm not sure how it worked before... if you begin a path with "/", you're basically telling PHP to go to the root of the drive, so I'm not sure why it's a 'problem' when it does.

I would say that even though you don't want to, the solution is to go through your scripts and use correct paths.

Hi, thanks for your response. Are you saying that starting a path with "/" shouldn't work?

I'm saying that if your path begins with a "/", you're defining an absolute path.

If you're on a Windows system, that's the same thing as opening My Computer and double-clicking on the "Local Drive (C🙂" icon. That's the root of the drive; if you see the next directory in the path ('Music' in your example above, '/Music/...'), then I'm saying you have the right path.

If you don't see it, however, then neither can PHP.

If you're trying to specify a path relative to the root of your website, that's an entirely different situation; to do that, you could use code such as:

include($_SERVER['DOCUMENT_ROOT'] . '/Music/...');

provided that the document root is configured correctly in PHP.
