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 transform
Transform
Transform is a simple library which aims to make using PHP's array_map
function a more pleasant experience - and resulting in cleaner code.
Transform is a collection of helper functions for common transform actions.
For a great companion library of predicates to make your array_filter code also look great, see Pentothal.
Namespace
From this point on, assume the TomPHP\Transform namespace is used like so:
Example
Take this code:
Using Transform this looks like this:
Installation
Using composer:
composer require tomphp/transform
Chaining
Multiple transformations can be composed using the chain function:
The Traversal Builder
If you want to chain together a collection of callMethod, getProperty and
getElement calls, the __() function provides a builder to write this in
a more elegant way.
Consider:
With the builder you can simply write:
Transformations
Object Transformations
T\callMethod(string $methodName, mixed ...$args)
T\callStatic(string $methodName, mixed ...$args)
T\getProperty(string $name)
Array Transformations
T\getElement(string|int $name)
String Transformations
T\prepend(string $prefix)
T\append(string $suffix)
T\concat(...$arguments)
Use __ as the placeholder for where you want the value inserted:
Generic Transformations
T\argumentTo(callable $callable, array $argments = [__])
You can also provide a list of arguments using __ as the placeholder for where
you want the value inserted:
T\newInstance(string $className, array $arguments = [__])
You can also provide a list of arguments using __ as the placeholder for where
you want the value inserted:
T\valueOrDefault(mixed $default, callable $predicate = null)
A predicate function can also be supplied:
T\valueOrDefault('negative number', function ($value) {
return $value >= 0;
})
// Is equivalent to:
function ($value) {
return $value >= 0 ? $value : 'negative number';
}
