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.

A lightweight and practical PHP utility library that offers a collection of commonly used helper functions for files, strings, arrays, and HTTP requests—designed to streamline development and support everyday PHP projects.
🌱 Many of these implementations are conceptually simple, but rewriting them repeatedly across projects can become quite tedious. To make things easier, I gathered these utilities in one place to avoid reinventing the wheel — saving both time and effort.
Installation

Purpose & Motivation
This is a typical "Developer's Time-Saving Toolkit." In everyday projects, you may often find yourself dealing with situations like:
Rewriting array operations over and over again;
- Searching StackOverflow every time you need to format file sizes;
- Copy-pasting checks to determine if a string is JSON, a phone number, or an email address;
- Having to refactor your utility classes whenever the project changes...
So, I’ve compiled these simple and frequently-used methods into this toolkit. It’s not about complexity or fancy features; the goal is to keep it simple, easy to use, and save you time and effort.
