仅重命名文件的一部分

Question

So far I have it so it changes it on the website, but how would I make it change the file's name on the server?

foreach(glob("vacation/*.jpg") as $image) {
  $tmpName = explode("_", $image);
  $tmpName = explode("~", $tmpName[1]);
  $md5 = md5($tmpName[0]);
  print "<p>{$md5}</p>";
}

This is what I have so far, it takes IMG_0401~timestamp.jpg and on the website shows it as IMG_99f97481f8214da999e3ccbe116f5334~timestamp.jpg

I want to actually rename the file to that

Answer 1

You need to use PHP's rename function:

http://php.net/manual/en/function.rename.php

foreach(glob("vacation/*.jpg") as $image) {
  $tmpName = explode("_", $image);
  $tmpName = explode("~", $tmpName[1]);
  $md5 = md5($tmpName[0]);
  print "<p>{$md5}</p>";
  rename($image, $md5);
}
