Hello,

I have got a warning in image_graphviz, i have viewed a post, who has a similar error. I have installed pear image_graphviz package(Image_GraphViz-1.2.1), I also installed graphviz.msi(Graphviz2.25.msi) in windows(But i don't know if does something with image_graphviz and if it does have some effects when i use image_graphviz).

Do i need to do something else?

Here is my code from pear image_graphviz site.

<?php
require_once 'Image/GraphViz.php';
error_reporting(E_ALL ^ E_NOTICE);  //Added E_NOTICE
$gv = new Image_GraphViz();
$gv->addEdge(array('wake up'        => 'visit bathroom'));
$gv->addEdge(array('visit bathroom' => 'make coffee'));
$gv->image();
?>

This is the warning:

Warning: fopen(C:\WINDOWS\Temp\gra50.tmp.svg) [function.fopen]: failed to open stream: No such file or directory in C:\wamp\bin\php\php5.3.0\PEAR\Image\GraphViz.php on line 210

Notice: Undefined variable: data in C:\wamp\bin\php\php5.3.0\PEAR\Image\GraphViz.php on line 218

Thanks Pekka Gaiser, I used error_reporting(E_ALL ^ E_NOTICE);. I don't know how to change the temp directory, but c:/windows/temp exists in my computer.

I haven't solve the problem. Thanks all for advice.
