How to batch modify file names in php

Can be modified in batches through the rename() function.

Function introduction:

The rename() function is used to rename files or directories.

Syntax format:

rename(oldname,newname,context)

If successful, this function returns TRUE. On failure, returns FALSE.

Example code:

<?php
header("Content-type: text/html; charset=utf-8");
//利用PHP目录和文件函数遍历用户给出目录的所有的文件和文件夹，修改文件名称
function fRename($dirname){
 if(!is_dir($dirname)){
  echo "{$dirname}不是一个有效的目录！";
  exit();
 }
 $handle = opendir($dirname);
 $i = 1;
 while(($fn = readdir($handle))!==false){

  if($fn!=&#39;.&#39;&&$fn!=&#39;..&#39;){
      echo "<br>将名为：".$fn."\n\r";
      $curDir = $dirname.&#39;/&#39;.$fn;
   if(is_dir($curDir)){
      fRename($curDir);
   }else{
      $path = pathinfo($curDir);
      //改成你自己想要的新名字
      $newname = $path[&#39;dirname&#39;].&#39;/&#39;.$i.&#39;.&#39;.$path[&#39;extension&#39;];
      echo "替换成:".$i.&#39;.&#39;.$path[&#39;extension&#39;]."\r\n";
      rename($curDir,$newname);
      $i++;
   }
  }
 }
}
//给出一个目录名称可以是相对路径，也可以是绝对路径
fRename(&#39;img\Gastroenterology&#39;);
exit();
?>
