PHP auto delete file after timer - php

Question

I've been working with this code all day but for some reason files won't get deleted after timer has run out.$zip_file_name is the file that I'd like to see gone after 30secs
$the_folder = '../test';
$zip_file_name = ("PHOENIX_fullbackup_$now.zip");
$download_file= true;
//$delete_file_after_download= true; doesnt work!!
class FlxZipArchive extends ZipArchive {
/** Add a Dir with Files and Subdirs to the archive;;;;; #param string $location Real Location;;;; #param string $name Name in Archive;;; #author Nicolas Heimann;;;; #access private **/
public function addDir($location, $name) {
$this->addEmptyDir($name);
$this->addDirDo($location, $name);
} // EO addDir;
/** Add Files & Dirs to archive;;;; #param string $location Real Location; #param string $name Name in Archive;;;;;; #author Nicolas Heimann
* #access private **/
private function addDirDo($location, $name) {
$name .= '/';
$location .= '/';
// Read all Files in Dir
$dir = opendir ($location);
while ($file = readdir($dir))
{
if ($file == '.' || $file == '..') continue;
// Rekursiv, If dir: FlxZipArchive::addDir(), else ::File();
$do = (filetype( $location . $file) == 'dir') ? 'addDir' : 'addFile';
$this->$do($location . $file, $name . $file);
}
} // EO addDirDo();
}
$za = new FlxZipArchive;
$res = $za->open($zip_file_name, ZipArchive::CREATE);
if($res === TRUE)
{
$za->addDir($the_folder, basename($the_folder));
$za->close();
}
else { echo 'Could not create a zip archive';}
if ($download_file)
{
ob_get_clean();
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private", false);
header("Content-Type: application/zip");
header("Content-Disposition: attachment; filename=" . basename($zip_file_name) . ";" );
header("Content-Transfer-Encoding: binary");
header("Content-Length: " . filesize($zip_file_name));
readfile($zip_file_name);
if ($handle = opendir ($zip_file_name)) {
while (false !== ($file = readdir($handle))) {
if (filectime($file)< (time()-30)) { // timer -30secs
unlink($file);
}
}
}
}
?>
Any help is greatly appreciated.thanks

you could delete zip file (if it already exists) prior to generating the zip file - so that old files are deleted first before new ones are generated:
E.g. (snippet of your code)
<?php
// Delete previous zip files
$old_files = glob($the_folder .'/*.zip');
foreach ($old_files as $old_file) {
unlink($old_file);
}
// Usage
$za = new FlxZipArchive;
$res = $za->open($zip_file_name, ZipArchive::CREATE);
if ($res === TRUE)
{
// Add Files to Zip
$za->addDir($the_folder, basename($the_folder));
$za->close();
// Download If enabled
if ($download_file)
{
ob_get_clean();
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private", false);
header("Content-Type: application/zip");
header("Content-Disposition: attachment; filename=" . basename($zip_file_name) . ";" );
header("Content-Transfer-Encoding: binary");
header("Content-Length: " . filesize($zip_file_name));
readfile($zip_file_name);
}
}
else
{
echo 'Could not create a zip archive';
}
?>
