Nest is a PHP class that lets you easily get and set values in nested arrays and objects without worrying about errors or missing data. You don't have to check if keys, properties or functions exist. It's all designed to fail gracefully.
Need a value from an array that is returned by a function that requires parameters on an object which is stored in an array? Nest will get it for you, or return a default value if the one you want isn't there. Easy.
You can get and set nested values. You can iterate over them with
Why do this...
When you could do this?
You don't have to worry about any key checks, or checking if things are set... Just fetch the value. You can specify a default value (
Use a string as the path parameter
We're going two levels in this time, so use an array for the path
What if we try to get something that isn't there? Does it error?
Or we can specify our own default in case of error
Who is it for?
Nest is for working with arrays and objects were you aren't always sure of the data. It works great with the Config class for storing configuration data for other classes or CLI scripts. But it can be used anywhere.
Where are the exceptions?
Nest doesn't throw any exceptions, that's the rule. Nest was designed to fail gracefully with default values instead of using exceptions.
What about the performance hit?
Although Nest can be used anywhere, it was built primarily for CLI apps where milliseconds don't matter. I've kept speed in mind but it's not a primary concern. At some point I will add benchmarks and timing and see how much I can shave off the execution time.
