Preface

After PHP5.3, a Java-like jar package named phar is supported. Used to package multiple PHP files into one file.

<?php
$phar = new Phar(&#39;swoole.phar&#39;);
$phar->buildFromDirectory(__DIR__.&#39;/../&#39;, &#39;/\.php$/&#39;);
$phar->compressFiles(Phar::GZ);
$phar->stopBuffering();
$phar->setStub($phar->createDefaultStub(&#39;lib_config.php&#39;));

The parameter of new Phar is the name of the compressed package. buildFromDirectory specifies the compressed directory, and the second parameter can specify the extension of the compressed file through regular rules.

Phar::GZ indicates using gzip to compress this file. Also supports bz2 compression. Just change the parameter to PHAR::BZ2.

After executing this code, a swoole.phar file is generated.

<?php
include &#39;swoole.phar&#39;;
include &#39;swoole.phar/code/page.php&#39;;
