Image not found. realpath() in PHP 5.3.5 for Windows returns blank. Bug fix is attached.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install timthumb.php on a PHP 5.3.5 installation for Windows
2. Run timthumb.php?src=myimage.png
3. "Could not find the internal image you specified"

What is the expected output? What do you see instead?
Expected input: display the image
What I see instead: 
A TimThumb error has occured
The following error(s) occured:

    Could not find the internal image you specified.

What version of the product are you using? On what operating system?
TimThumb version : 2.8.2

Please provide any additional information below.

The root cause is this:
Line 834: $real = realpath($base . $src);
Line 835: if(stripos($real, $this->docRoot) === 0){ 

In XAMMP 1.7.4 on Windows running PHP 5.3.5, the realpath method returns a path 
with backslash separated, instead of forward slashes. $this->docRoot is 
forward-slashed, so the stripos does not return 0 (it returs FALSE).

The fix is:

Line 835: if(stripos(preg_replace("/\\\/", "/", $real), $this->docRoot) === 0) {

This solved the issue in my machine.

I fixed it replacing

Line 835: if(stripos($real, $this->docRoot) === 0){ 

with

Line 835: if(stripos($real, $this->docRoot) == false){ 

Hope this helps...

I had this issue and BOLADO's fixed worked for me too:

if(stripos($real, $this->docRoot) === 0){

SHOULD BE

if(stripos($real, $this->docRoot) == 0){

Thanks for this. I've added it to the trunk.

Thank you, this fixed my issue, as well.

I was using 2.8.5 version and above fix didn't work for me.
After a bit of hacking I fixed it by replacing line #817

$docRoot = @$_SERVER['DOCUMENT_ROOT'];

with this one:

$docRoot=dirname(dirname($_SERVER['SCRIPT_FILENAME']));

Hope it helps.

Any help would be appreciated

you need to update to the latest version before posting bug requests. TimThumb 
is currently on 2.8.9 and a number of bugs have been fixed.

THANK YOU VERY MUCH!! it worked :)

On my system the $_SERVER['DOCUMENT_ROOT'] was not giving the right path
After some hard debugging timthumb.php I fixed the issue using a 
timthumb-config.php config containing the line:

$_SERVER['DOCUMENT_ROOT'] = '/path/to/wordpress/home/directory/';

replace /path/to/wordpress/home/directory/ to your absolute wordpress root 
(commonly something like /var/www/... etc.)

Where should the timthumb-config.php be placed?

Thank you very much to the author of comment 16! It works for me 
(Version 2.8.11). 

The timthumb-config.php should be placed in the same place that timthumb.php.

Same problem but still cant fix it. Version 2.8.11

Tried to make a timthumb-config.php but not sure if I used the correct 
/path/to/wordpress/home/directory/
Using Justhost 
In File manager I can see /home5/moonskoh/public_html/ as the folder I 
installed Wordpress into.  is this the path I need to use or should anything 
come before /home5 ?

( Apologies for the probably dumb newbie question, dont know anything about 
this really. )

My problem is solved. It lied in the timthumb-config.php NOT in the 
timthumb.php itself.

I fix it with adding following command to the top of timthumb-config.php file

$_SERVER['DOCUMENT_ROOT'] = dirname( __FILE__ );

If you get this error at only localhost you can use like that also.

if($_SERVER["HTTP_HOST"] == 'localhost'){
$_SERVER['DOCUMENT_ROOT'] = dirname( __FILE__ );
}
