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

Posted by: admin April 23, 2020 Leave a comment

Questions:

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.$file);
           }
        }
     }
   }
?>
How to&Answers:
(time()-filectime($path.$file)) < 86400

If the current time and file’s changed time are within 86400 seconds of each other, then…

 if (preg_match('/\.pdf$/i', $file)) {
     unlink($path.$file);
 }

I think that may be your problem. Change it to > or >= and it should work correctly.

Answer:

<?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")

Answer:

  1. You want > instead.
  2. Unless you’re running on Windows, you want filemtime() instead.

Answer:

<?php   
$dir = getcwd()."/temp/";//dir absolute path
$interval = strtotime('-24 hours');//files older than 24hours

foreach (glob($dir."*") as $file) 
    //delete if older
    if (filemtime($file) <= $interval ) unlink($file);?>

Answer:

working fine

$path = dirname(__FILE__);
if ($handle = opendir($path)) {
while (false !== ($file = readdir($handle))) {
$timer = 300;
$filetime = filectime($file)+$timer;
$time = time();
$count = $time-$filetime;
    if($count >= 0) {
      if (preg_match('/\.png$/i', $file)) {
        unlink($path.'/'.$file);
      }
    }
}
}

Answer:

$path = '/cache/';
// 86400 = 1day

if ($handle = opendir($path)) {
     while (false !== ($file = readdir($handle))) {
        if ( (integer)(time()-filemtime($path.$file)) > 86400 && $file !== '.' && $file !== '..') {
                unlink($path.$file);
                echo "\r\n the file deleted successfully: " . $path.$file;
        } 
     }
}
