「どうしてこうなった」 って感じなので、もうちょっときれいにしたいですよね。そこで自作のスタブをセットしてみましょう。実は composer.phar もこの手段を採っています。
src以下にあるPHPファイルを全てbuild/test.pharにまとめる
$pharpath = __DIR__ . '/build/test.phar';
if (is_file($pharpath)) {
unlink($pharpath);
}
$phar = new \Phar($pharpath, 0, basename($pharpath));
$phar->setStub('<?php
spl_autoload_register(function ($class) {
$path = "phar://" . __FILE__ . DIRECTORY_SEPARATOR .
str_replace("\\", DIRECTORY_SEPARATOR, $class) . ".php";
if (is_file($path)) {
require $path;
}
});
__HALT_COMPILER(); ?>
');
$phar->buildFromDirectory(__DIR__ . '/src', '/\.php\z/');
実際にこれを利用するときは(正しくスタブを書いていれば)従来通り以下のコードでOKです。
require 'test.phar';
