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 typed
Typed
This library allows you to create typed variables in PHP 7.4 +
Composer installation :
Usage Example :
callable => func, array => { arr, keyset, vector, set }
Since callable and array cant be used for function names, instead i have used func for callable and arr for array.
keyset, vector and set are just helper to help you create an array of keys ( keyset = arr(array_keys($value)) ), an array of values ( vector = arr(array_values($value)) ) and an array of unique values ( set = arr(array_unique($value)) ).
typed
typed() is a function to help you create a typed variables based on the type of the passed variable, currently it supports string, int, float, bool, object and iterable. it was suggested by @mikesherov on twitter.
purge, clean, delete and c
As mentioned here and here, memory leak is a huge issue here, if a specific function created a typed variable, the variable will still exist inside the repository even after execution, for this i made some helper functions that allow you to remove variables from the repository.
Typed\purge()will delete every reference registered in the repository, you can call this function at the end of every request/response cycle in a web application per example.Typed\clean(string $namespace = 'default')this function will delete every reference to a typed variable in a specific namespace as shown in the example above, its recommended to use a unique namespace every time you use typed variables and callclean()to ensure there's no memory leak.Typed\filter(mixed $value, string $namespace = 'default')this function will delete the every created reference to a typed variable with the given value in a specific namespace.-
Typed\delete(mixed $value, string $namespace = 'default')similar to whatTyped\filterdoes, this function allows you to delete the last created reference to a typed variable with the given value in a specific namespace. example : Typed\cthis function accepted a callable that take no arguments, the callable will be called insidec( container ) and all the assigned typed variables in the time of the call would be deleted afterward, this makes it easier to ensure that function calls don't cause any memory leak. example :
