## Frequently asked questions

### What is InitPHP?

InitPHP is an open source collection of 27 standalone PHP libraries covering database access, HTTP routing, caching, encryption, sockets, queues and more. It is not a framework: there is no kernel, no service container you must boot, and no shared runtime. Each package is installed and used on its own.

### Do I have to use all of the libraries together?

No. Every package is published separately on Packagist and depends only on what it genuinely needs. You can install a single library into an existing application without adopting anything else from the ecosystem.

### How do I install an InitPHP library?

Each library is a Composer package under the initphp vendor namespace. Run composer require initphp/<package>, for example composer require initphp/router or composer require initphp/database. Every library page on this site lists its exact install command.

### Which PHP versions does InitPHP support?

It depends on the package. The minimum ranges from PHP 5.6 for the smallest utility libraries up to PHP 8.2 for the newest ones; most current releases target PHP 8.1 or later. The required version is listed on each library's page.

### Can I use InitPHP libraries with Laravel, Symfony or CodeIgniter?

Yes. The libraries are framework-agnostic and interoperate through PSR interfaces, so they can be dropped into any PHP application or framework that uses Composer.

### Which PSR standards does InitPHP implement?

InitPHP HTTP implements PSR-7, PSR-17 and PSR-18; Container implements PSR-11; Cache implements PSR-16; Logger implements PSR-3; and Router consumes PSR-7 and PSR-11. That means they can be swapped for any other compliant implementation.

### Is InitPHP free for commercial use?

Yes. Every InitPHP package is released under the MIT license, which permits commercial use, modification and redistribution as long as the copyright notice is retained.

### Where is the documentation?

Each package documents itself in its GitHub wiki, linked from that library page on this site alongside its source repository and its Packagist listing.
