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 var-type
VarType
VarType is a powerful PHP library that generates detailed type information from PHP variables, with a focus on producing "object-like array" and "array shape" representations. It's designed to enhance static analysis capabilities and improve IDE autocompletion and type inference.
Features
- Generate detailed type information for any PHP variable
- Produce "object-like array" and "array shape" representations
- Support for arrays, objects, and scalar types
- Distinguish between indexed arrays and associative arrays (array shapes)
- Recursively analyze nested structures
- Compatible with static analysis tools like Psalm and PHPStan
- Enhance IDE autocompletion and type prediction
Installation
Install VarType using Composer:
Usage
Here's a quick example of VarType in action:

Advanced Usage
You can also use the VarType class as an invokable:
Type Representations
VarType uses the following syntax to represent different types:
- Scalar types:
int,float,bool,string,null - Arrays:
- Indexed arrays:
array<type1|type2|...> - Associative arrays (array shapes):
array{key1: type1, key2: type2, ...}
- Indexed arrays:
- Objects (object-like arrays):
ClassName{property1: type1, property2: type2, ...}
Why VarType?
-
Enhanced Static Analysis: VarType provides detailed type information that can be used with tools like Psalm and PHPStan for more accurate static analysis.
-
Improved IDE Support: The detailed type strings generated by VarType can enhance IDE autocompletion and type inference, making development more efficient.
-
Detailed Type Information: While PHP's built-in functions can provide basic type information, VarType offers much more detailed type representations, including object-like arrays and array shapes.
-
Debugging Aid: Quickly understand the structure of complex variables, including nested object-like arrays and array shapes.
- Documentation: Generate precise type information for APIs or function parameters, improving code readability and maintainability.
VarType - Unleash the full potential of PHP type information!
