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 haphproxy
haphproxy
haphproxy is a PHP library which can parse and create HAproxy configuration files.
The library operates on the configuration at a low level. A configuration is made up of sections (e.g. global and
default). Each section is made up of parameters (e.g. mode and timeout). Each parameter has a value associated
with it, e.g. a parameter named timeout can have a value of timeout 30s.
Since the library doesn't actually understand how HAproxy works, it is only guaranteed to generate syntactically valid
configurations. For proper validation, please use haproxy -f <configurationFile> -c.
Requirements
- PHP 5.6 or newer
Installation
Install via Composer:
Usage
Reading a configuration
This example reads an existing configuration file, parses it and dumps it back as a string:
Writing a configuration
This example shows how you can dynamically create a configuration:
The above results in the following configuration being generated:
Changing the output formatting
You can change the indentation and preface of the generated configuration. Changing the preface may be useful when used in combination with other tools to indicate whether the configuration file has been generated dynamically or not.
Inspecting a configuration
You can access the individual parameters of each section like this:
You can also loop through specific sections of a configuration:
Magic comments
A magic comment is a comment that beings with HAPHPROXY_COMMENT. In contrast to normal comments, these are not
omitted during parsing and writing. Magic comments only apply to sections and can be useful to store arbitrary data.
The above results in the following configuration being generated:
Testing
The test suite leaves all the validation of the generated configurations to HAproxy itself, so in order to run the test
suite you'll need to have haproxy in your path. To run the test suite, run php vendor/bin/phpunit.
There is a Vagrantfile shipped with the library which automatically provisions itself with all the required software.
