<h1>phpCallGraph -
A Call Graph Generator for PHP</h1>
<div class="textt">
<b>phpCallGraph</b> is a tool to generate static call graphs for
<a href="http://www.php.net/">PHP</a> source code.
Such a graph visualizes the call dependencies among methods or functions of an application.
Arrows represent calls from one method to another method.
Classes are drawn as rectangles containing the respective methods.
The graphs can be leveraged to gain a better understanding of large PHP applications or even to <a href="http://phpcallgraph.svn.sourceforge.net/viewvc/phpcallgraph/docs/workshop-2007-12-03-refactoring-and-unit-testing/">debunk design flaws</a> in them.
<p>
The example call graph on the right shows <!--a part of--> the main class of phpCallGraph itself
and the internal dependencies among its methods.
It is also possible to visualize calls to internal functions of PHP
and to some extend call dependencies among different classes.
Have a look at the <a href="examples/">example call graphs</a> to get an impression.
</p>
<p>
The core of the call graph generator forms an
<a href="http://phpcallgraph.sourceforge.net/examples/phpcallgraph/phpcallgraph-library.png">object-oriented PHP5 library</a>,
<!--<a href="">API Docs</a>-->
which may also be integrated in other projects.
It leverages the
<a href="http://instantsvc.sourceforge.net/">InstantSVC CodeAnalyzer</a>
and <a href="http://www.graphviz.org/">DOT</a>.
On top of it, a
<a href="http://phpcallgraph.svn.sourceforge.net/viewvc/*checkout*/phpcallgraph/trunk/readme.txt">commandline application</a>
allows easy creation of call graphs in various formats, e.g. text, png, jpg or svg.

I'm developing phpCallGraph just for fun in my spare time
and I'm always eger on getting
<a href="https://lists.sourceforge.net/lists/listinfo/phpcallgraph-general">feedback</a>
or
<a href="http://sourceforge.net/tracker/?group_id=204008">feature requests</a>.
Especially, let me know if you are analyzing any free software,
since I collect <a href="examples/">example call graphs</a>.
If you would like to work with the code or
test some own visualization ideas, feel free to join the project.
I'm happy to give anyone, who is interested, access to the
<a href="http://sourceforge.net/svn/?group_id=204008">SVN Repository</a>.
Just drop me a mail to
<a href="https://sourceforge.net/sendmessage.php?touser=1029473">fakko at users dot sf dot net</a>.
