A Control-Flow-Graph implementation in Pure PHP.

To bootstrap the parser, you need to give it a PhpParser instance:

$parser = new PHPCfg\Parser(
    new PhpParser\Parser(new PhpParser\Lexer)
); 

Then, just call parse on a block of code, giving it a filename:

$block = $parser->parse(file_get_contents(__FILE__), __FILE__);

To dump the graph, simply use the built-in dumper:

$dumper = new PHPCfg\Printer\Text();
echo $dumper->printCFG(array($block));
