FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package php-analyzer
PHP-Analzyer
Homepage: https://github.com/mfn/php-analyzer
Blurb
A framework for performing static PHP source analysis. The modular concept hands analysis over to Analyzers which report back any possible warnings/errors.
Install
Via composer:
Usage
A command line tool is provided: php_analyzer.php analyze <files or dirs>
See the --help switch for more details.
What analysis is performed?
All files are run through the nikic/PHP-Parser and after that an internal graph of the classes/interfaces is built.
All analyzers available are run against the sources reports are generated.
The following analysis is currently performed:
- detection of missing method implementations of abstract classes
- detecting of missing method implementations of interfaces
- incompatibility of methods declared in interfaces
- methods defined abstract on an interface
Probably a bit pointless because the php linter detects this. - warns when using dynamic class instantiation, i.e.
new $foo - warns when encountering empty exception catch blocks

Graphviz
The internal ObjectGraph lends
itself to generate a class relationship diagram for which a graphviz generator
exists. This will produce a .dot file which can be further used with the
Graphviz package to generate graphics from it:
php_analyzer.php graphviz yoursource/ > myproject.dot
See --help for more options.
To convert this to e.g. png the aforementioned graphviz package has to be
installed on your system. This includes the dot command which can be used to
generate a PNG file:
dot -Tpng myproject.dot > myproject.png
Configuration
If you want to use a differnet set of analyzers or you've written your own and
want to use them, you can use the --config <file> option.
The file is a plain PHP file simply returning an array of analyzers you want to run. See res/defaultAnalyzerConfiguration.php for an example.
TODOs / Ideas
- the analyzers depending on the graph have no logic whether they've visited a node already or not; thus visiting the same nodes/methods multiple times
- Use
namespacedNameproperty generated by\PhpParser\NodeVisitor\NameResolver - Add support for traits
Contribution
- one feature per branch/PR
- coding standard is PSR-2
