While 99% of PHP servers run PHP 5.2 or higher, 12% of all servers are still running PHP 5.2 or lower ([source](http://w3techs.com/technologies/details/pl-php/5/all)). ### Differences from [Symfony's ClassLoader component](https://github.com/symfony/ClassLoader) [](#differences-from-symfonys-classloader-component) The primary difference is naming conventions of Symfony's classes. Instead of the `\Symfony\Component\ClassLoader` namespace (and sub-namespaces), instead prefix the class names with `ehough_pulsar` and follow the [PEAR naming convention](http://pear.php.net/manual/en/standards.php). A few examples of class naming conversions: ``` \Symfony\Component\ClassLoader\ApcClassLoader -----> ehough_pulsar_ApcClassLoader \Symfony\Component\ClassLoader\UniversalClassLoader -----> ehough_pulsar_UniversalClassLoader ``` ### How to use [](#how-to-use) Please see the [Symfony documentation](https://github.com/symfony/ClassLoader) for general use instructions. ### ComposerClassLoader [](#composerclassloader) `pulsar` also includes a novel class for Composer-based projects, `ehough_pulsar_ComposerClassLoader`, which features: - All functionality of the [UniversalClassLoader](https://github.com/symfony/ClassLoader/blob/master/UniversalClassLoader.php) - Recognition and proper handling of [Composer autoloading](http://getcomposer.org/doc/01-basic-usage.md#autoloading) Simple to create and use. Just point it to your `vendor` directory: ``` $classLoader = new ehough_pulsar_ComposerClassloader('/path/to/your/vendor/directory'); ``` ### Releases and Versioning [](#releases-and-versioning) Releases are synchronized with the upstream Symfony repository. e.g. `ehough/pulsar v2.3.1` has merged the code from `symfony/ClassLoader v2.3.1`. ### Health Score 35 — LowBetter than 79% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity22 Limited adoption so far Community26 Small or concentrated contributor base Maturity64 Established project with proven stability Bus Factor1 Top contributor holds 70.5% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
