symfony符号链接和src的路径解析

Question

如果您的服务器上有设置，例如：

/path/sites/site1
  app/
  bin/
  web/
  src/
  vendor/ -> /path/vendor/Symfony_2.0.3/vendor (symbolic links)
/path/sites/site2
  app/
  bin/
  web/
  src/
  vendor/ -> /path/vendor/Symfony_2.0.3/vendor (symbolic links)
/path/vendor/Symfony_2.0.3/vendor

那么symfony如何知道在哪里找到src文件夹等？

如php中的 __ DIR __ 等会将/ path / sites / site2 / vendor解析为实际的实际路径......

Answer 1

通过反思！

Symfony 1.x

sfProjectConfiguration.class.php

static public function guessRootDir()
{
    $r = new ReflectionClass('ProjectConfiguration');

    return realpath(dirname($r->getFileName()).'/..');
}

Symfony 2

的Symfony \元器件\ HttpKernel \内核

public function getRootDir()
{
    if (null === $this->rootDir) {
        $r = new \ReflectionObject($this);
        $this->rootDir = str_replace('\\', '/', dirname($r->getFileName()));
    }

    return $this->rootDir;
}
