5 ways to implement recursive directories in PHP

This article mainly introduces 5 ways to implement recursive directories in PHP, which are mainly implemented by using some loops. Interested friends can refer to it.

During project development, it is inevitable to create folders on the server, such as the directory when uploading images, the directory when parsing templates, etc. This is not used in my current project, so I summarized several methods of creating directories in a loop.

Method 1: Use glob loop

Method 2: Use dir && read loop

read()) !== false) {
 
    $p = realpath($path . '/' . $file);
    if ($file != "." && $file != "..") {
      $arr[] = $p;
    }
 
    if (is_dir($p) && $file != "." && $file != "..") {
      myscandir2($p, $arr);
    }
  }
}
?>

Method 3: Use opendir && readdir loop

Method 4: Use scandir loop

Method 5: Use SPL loop

##

 getFilename();
    $p = realpath($path . '/' . $file);
    if (!$fileinfo->isDot()) {
      $arr[] = $p;
    }
    if ($fileinfo->isDir() && !$fileinfo->isDot()) {
      myscandir5($p, $arr);
    }
  }
}
?>
