PHP中的imagecreatefromjpeg（）函数出错

Question

When using the below php code it shows an error

<?php
$path="/hari002244/album/f41b6b54811c.jpg";
$src = imagecreatefromjpeg($path);
?>

It shows

SCREAM: Error suppression ignored for
Warning: imagecreatefromjpeg(/hari002244/album/f41b6b54811c.jpg): failed to open stream: No such file or directory in C:\wamp\www
ewEmptyPHP.php on line 3

But when using

<?php
$path="f41b6b54811c.jpg";
$src = imagecreatefromjpeg($path);
?>

It doesn't show any error.

I had typed the path in URL bar and checked whether file exists.It is working perfectly.

Can you tell me why this error occurs? and also how to overcome this?

Thanks in advance.

Answer 1

The first path, "/hari002244/album/f41b6b54811c.jpg" is an absolute path, it starts from the root of the whole file system. Chances are, this path does not exist.

In the second case, it is just a filename "f41b6b54811c.jpg" which is relative to / located in the current working directory, which of course exists.
