The used SSA construction algorithm is based on "Simple and Efficient Construction of Static Single Assignment Form" by Braun et al. This algorithm constructs SSA form directly from the abstract syntax tree, without going through a non-SSA IR first. If you're looking for dominance frontiers, you won't find them here... The constructed SSA form is minimal and pure (or is supposed to be). Usage ----- [](#usage) To bootstrap the parser, you need to give it a `PhpParser` instance: ``` $parser = new PHPCfg\Parser( (new PhpParser\ParserFactory)->create(PhpParser\ParserFactory::PREFER_PHP7) ); ``` Then, just call parse on a block of code, giving it a filename: ``` $script = $parser->parse(file_get_contents(__FILE__), __FILE__); ``` To dump the graph, simply use the built-in dumper: ``` $dumper = new PHPCfg\Printer\Text(); echo $dumper->printScript($script); ``` ### Health Score 25 — LowBetter than 35% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity8 Limited adoption so far Community18 Small or concentrated contributor base Maturity49 Maturing project, gaining track record Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
