This article mainly introduces PHP to obtain files in the directory. Interested friends can refer to it. I hope it will be helpful to everyone.

1. Get the files in the directory, excluding subdirectories

//获取某目录下所有文件、目录名(不包括子目录下文件、目录名) 
  $handler = opendir($dir); 
  while (($filename = readdir($handler)) !== false) {//务必使用!==,防止目录下出现类似文件名“0”等情况 
    if ($filename != "." && $filename != "..") { 
        $files[] = $filename ; 
      } 
    } 
  } 
  closedir($handler); 
    
//打印所有文件名 
foreach ($filens as $value) { 
  echo $value."<br />"; 
}
Copy after login

2. Get the files in the directory All files, including subdirectories

function get_allfiles($path,&$files) { 
  if(is_dir($path)){ 
    $dp = dir($path); 
    while ($file = $dp ->read()){ 
      if($file !="." && $file !=".."){ 
        get_allfiles($path."/".$file, $files); 
      } 
    } 
    $dp ->close(); 
  } 
  if(is_file($path)){ 
    $files[] = $path; 
  } 
} 
   
function get_filenamesbydir($dir){ 
  $files = array(); 
  get_allfiles($dir,$files); 
  return $files; 
} 
   
$filenames = get_filenamesbydir("static/image/"); 
//打印所有文件名,包括路径 
foreach ($filenames as $value) { 
  echo $value."<br />"; 
}
Copy after login
