php script to delete files older than 24 hrs, deletes all files

Question

I wrote this php script to delete old files older than 24 hrs, but it deleted all the files including newer ones:

<?php   $path = 'ftmp/';   if ($handle = opendir($path)) {      while (false !== ($file = readdir($handle))) {         if ((time()-filectime($path.$file)) < 86400) {              if (preg_match('/\.pdf$/i', $file)) {               unlink($path.$file);            }         }      }    } ?> 

Answer 1

<?php  /** define the directory **/ $dir = "images/temp/";  /*** cycle through all files in the directory ***/ foreach (glob($dir."*") as $file) {  /*** if file is 24 hours (86400 seconds) old then delete it ***/ if(time() - filectime($file) > 86400){     unlink($file);     } }  ?> 

You can also specify file type by adding an extension after the * (wildcard) eg

For jpg images use: glob($dir."*.jpg")

For txt files use: glob($dir."*.txt")

For htm files use: glob($dir."*.htm")
