PHP method to modify file suffix names in batches_php tips

The example in this article describes the method of batch modifying file suffix names in PHP. Share it with everyone for your reference. The details are as follows:

/**
 * 批量修改文件后缀名
 * @param $path 文件夹路径
 * @param $sext 原文件后缀名 ($sext=all说明整个目录的所有文件)
 * @param $dext 目的文件后缀名
 * @return void 
 */
function foreachDir($path,$sext,$dext){ 
  $handle=opendir($path); 
  if($handle){ 
  while (false !== ($file = readdir($handle))) { 
   if($file!="." && $file!='..'){ 
    if(is_dir($path.$file)){ 
     foreachDir($path.$file); 
    }else{ 
     $ext = strripos($file,'.'); 
     $fileName = substr($file,0,$ext); 
     $src = $path.'/'.$file;
     $dest = $path.'/'.$fileName.'.'.$dext;
     if($sext!="all"){
      if($sext == substr($src,0-strlen($sext))) rename($src,$dest); 
     }else{
      rename($src,$dest); 
     }
    } 
   } 
  } 
   return false; 
  } 
}
foreachDir('C:\Users\chenlinzhong\Desktop\redis-stable\src','c','txt');

I hope this article will be helpful to everyone’s PHP programming design.
