Features

shared.phar is a streets ahead PHP autoloader.

• Self-contained in a single compressed phar
• Based on a class map
• Can be updated easily by invoking it from the command line
• Phar collections become first class citizens
• Interprets identifiers case-insensitively (as PHP does)
• Tokenizes plain *.php and phar://* includes for identifier declarations
• Is meant for /usr/share/php handling, but can be used project-locally
• Prepares rfc:function_autoloading userland support
• Indifferent to PSR-0/4 constraints, works atop any legacy or custom directory scheme
• The phar may also be split up

And it's public domain.

Usage

It can be utilized easily with:

 include_once("shared.phar");

And updated manually on the command line:

 php ./shared.phar

Or implicitly on development setups by declaring an AUTOLOADER_UPDATE environment variable.
