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 binary-driver
Binary Driver
Binary-Driver is a set of PHP tools to build binary drivers.
Why ?
You may wonder Why building a library while I can use exec or
symfony/process ?.
Here is a simple answer :
-
If you use
exec,passthru,system,proc_openor any low level process handling in PHP, you should have a look to symfony/process component that will provide an OO portable, testable and secure interface to deal with this. It seems easy at first approach, but if you look at this component unit tests, you will see that handling process in a simple interface can easily become a nightmare. - If you already use symfony/process, and want to build binary drivers, you will always have the same common set of methods and objects to configure, log, debug, and generate processes. This library is a base to implement any binary driver with this common set of needs.
AbstractBinary
AbstractBinary provides an abstract class to build a binary driver. It implements
BinaryInterface.
Implementation example :
Binary detection troubleshooting
If you are using Nginx with PHP-fpm, executable detection may not work because of an empty $_ENV['path'].
To avoid having an empty PATH environment variable, add the following line to your fastcgi_params
config file (replace /your/current/path/ with the output of printenv PATH) :
Logging
You can log events with a Psr\Log\LoggerInterface by passing it in the load
method as second argument :
Listeners
You can add custom listeners on processes.
Listeners are built on top of Evenement
and must implement Alchemy\BinaryDriver\ListenerInterface.
Bundled listeners
The debug listener is a simple listener to catch stderr and stdout outputs ;
read the implementation for customization.
ProcessBuilderFactory
ProcessBuilderFactory ease spawning processes by generating Symfony [Process] (http://symfony.com/doc/master/components/process.html) objects.
Configuration
A simple configuration object, providing an ArrayAccess and IteratorAggregate
interface.
Same example using the ArrayAccess interface :
