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 get-from
get-from
Function to retrieve values from objects without painfully checking if the value isset. Inspired by and ported from
the great get-in library for arrays from Igor Wiedler.
For example, to access a nested property ->foo->bar->baz, you must do something like this:
Enough already! get-from provides a better way:
get_from is specially handy when dealing with deeply nested objects like those generated by SimpleXML.
Installation
Through composer:
Usage
get_in
Retrieve value from a nested structure using a list of keys:
Non existent keys return null:
You can provide a default value that will be used instead of null:
Changelog
Version 1.0 (9 March 2014)
- Initial release
Inspiration
This library is a complete ripoff of Igor Wiedler's get-in library. Even this README file is largely inspired by Igors work. Scandalous.
I created this library/function when I wanted to clean up the code dealing with XML from an external web service and I realised that get-in only works for arrays and not for objects.
