  前两天在一个PHP项目中需要获取指定文件夹的大小,因为文件夹可能有很多子文件夹及子文件夹构成,所以在网上找了一圈没找到合适的,有的是不能正确获取多层嵌套的文件夹,有的是代码量太多,效率低。最后自己琢磨写了一个方法,效率还不错,而且可以获取到任意多层嵌套的文件夹大小。

  代码:

  

  function getFolderSize($dir){

  $count_size = 0;

  $count = 0;

  $dir_array = scandir($dir);

  foreach($dir_array as $key=>$filename){

  if($filename!="" && $filename!="."){

  if(is_dir($dir."/".$filename)){

  $new_foldersize = foldersize($dir."/".$filename);

  $count_size = $count_size+ $new_foldersize;

  }else if(is_file($dir."/".$filename)){

  $count_size = $count_size + filesize($dir."/".$filename);

  $count++;

  }

  }

  }

  return $count_size;

  }

  ?>

  调用:

  

  $folder_name = "textFolder";

  echo getFolderSize($folder_name);

  ?>

  上面getFolderSize这个函数返回的文件夹大小是以字节为单位的,为了更完善的实现功能,这里补充一个函数,将字节转换为KB,MB,GB,TB等单位。

  转换函数:

  

  function sizeFormat($bytes){

  $kb = 1024;

  $mb = $kb * 1024;

  $gb = $mb * 1024;

  $tb = $gb * 1024;

  if (($bytes >= 0) && ($bytes

  return $bytes . ' B';

  } elseif (($bytes >= $kb) && ($bytes

  return ceil($bytes / $kb) . ' KB';

  } elseif (($bytes >= $mb) && ($bytes

  return ceil($bytes / $mb) . ' MB';

  } elseif (($bytes >= $gb) && ($bytes

  return ceil($bytes / $gb) . ' GB';

  } elseif ($bytes >= $tb) {

  return ceil($bytes / $tb) . ' TB';

  } else {

  return $bytes . ' B';

  }

  }

  ?>

  最终调用:

  

  $folder_name = "textFolder";

  echo sizeFormat(getFolderSize($folder_name));

  ?>

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
