rated 0 times [ 2] [ 0] / answers: 1 / hits: 7384 / 1 Year ago, sat, april 22, 2023, 8:48:39

What I want to do is install GraphViz for PHP on Ubuntu.

I tried pear install Image_GraphViz, it installed but does not work for me.

Then I tried downloading the file from here.

File name : libgv-php5_2.32.0-1~raring_amd64.deb When I run the file it says dependency is not satisfiable libgraphviz4.

All I want to do is run the code below which is from their documentation. Unfortunately I can not find GraphViz.php to download.

<?php

require_once 'GraphViz.php';



$gv = new Image_GraphViz();

$gv->addEdge(array('wake up'        => 'visit bathroom'));

$gv->addEdge(array('visit bathroom' => 'make coffee'));

$gv->image();

?>

How can I fix this issue? Where can I download GraphViz.php

Just install the libgv-php5 package:

PHP5 bindings for graphviz

Graphviz is a set of graph drawing tools. See the description of the graphviz
package for a full description.

This package contains the PHP5 bindings.

Using your favourite package management, e.g. apt-get, do:

sudo apt-get install libgv-php5

This should install the Graphviz for PHP in the paths used by the Ubuntu packaged version of PHP (automatically enabled in the php.ini .d directory).

You will then have to change your require_once statement to match the Ubuntu packaged version. From the manpage:

#!/usr/bin/php

<?

include('libgv-php5/gv.php');

...

?>

Also don't forget to restart your webserver if you're running PHP as a module.
