示例

示例 #1 getSubPath() example

$directory = '/tmp';
      
      $it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory));
      
      foreach ($it as $file) {
          echo 'SubPathName: ' . $it->getSubPathName() . "\n";
          echo 'SubPath:     ' . $it->getSubPath() . "\n\n";
      }

以上示例的输出类似于：

     SubPathName: fruit/apple.xml
     SubPath:     fruit
     
     SubPathName: stuff.xml
     SubPath:     
     
     SubPathName: veggies/carrot.xml
     SubPath:     veggies
