How to rename zipped filename? - php

Question

So i have code to move from 1 dir to another dir file and make that file zipped.
That i need:
Rename zipped filename to second "-" symbol.
Example: i got zipped filename "SOMETEXT-de_dust2-20123323.dem.zip". I need that filename to be only "SOMETEXT.dem.zip"
So just remove all text until second -"-"
Any suggestion?
Thanks for helping me to understand code :)
My CODE:
<?php
//error_reporting(E_ALL);
//set_time_limit(0);
$path = "MIX1/cstrike";
$path2 = "/var/www/html/public/";
$to_dirs = array('/demos/');
$from_dirs = array('/demos/');
$filesizes = array();
//первый проход запоминаем размеры
foreach($from_dirs as $from_dir)
{
$demos_dir = opendir($path.$from_dir);
while (false!==($file=readdir($demos_dir)))
{
if ($file!='.'&&$file!='..'&&strpos($file,'.dem')!==false)
{
$fsize=filesize($path.$from_dir.$file);
if ($fsize<50000000)
{
$filesizes[$file]=$fsize;
}
else{
// echo "<br/>bad file:",$file, ", size = ", $fsize;
}
}
}
closedir($demos_dir);
}
//echo date("h:i:s");
sleep(3);
clearstatcache ();
//второй проход пермещаем
$i=0;
foreach($from_dirs as $from_dir)
{
$to_dir=$from_dirs[$i];
$demos_dir = opendir($path.$from_dir);
while (false!==($file=readdir($demos_dir)))
{
if ($file!='.'&&$file!='..'&&strpos($file,'.dem')!==false)
{
$fsize=0;
$fsize=filesize($path.$from_dir.$file);
if ($fsize<50000000)
{
if ($fsize==$filesizes[$file])
{
//echo "<br>ѕеремещаем файл ",$file," размер не изменилс¤; было ",$filesizes[$file]," стало, ".$fsize,";";
move_demo($file, $from_dir, $to_dir);
}
else
{
//echo "<br>","размер изменилс¤ у файла ", $file;
}
}
else
{
//echo "<br/>bad file:",$file, ", size = ", $fsize;
}
}
}
$i++;
closedir($demos_dir);
}
function move_demo($filename, $from_dir, $to_dir)
{
//echo $filename,"from ",$from_dir," to ",$to_dir,"<br>";
global $path, $path2;
if (file_exists($path2.$to_dir.$filename.".zip"))
unlink($path2.$to_dir.$filename.".zip");
echo "$path$from_dir$filename\n";
echo "$path2$to_dir$filename\n\n";
$data = file_get_contents($path.$from_dir.$filename);
$gzdata = gzencode($data, 9);
unset($data);
$fp = fopen($path2.$to_dir.$filename.".zip", "xb+");
//$fp = fopen($path.$to_dir.$filename.".zip")
fwrite($fp, $gzdata);
unset($gzdata);
fclose($fp);
unlink($path.$from_dir.$filename);
}
?>

Have a look at rename().
Here's a PoC:
function move_files($src, $dst)
{
$dh = opendir($src);
if (!$dh) {
return false;
}
// Combine the letters before the first dash/hyphen (-),
// and the letters after (and including) the first dot/period (.)
// after the first dash/hyphen (-).
$regex = '/^(.+?)-(?:.+?)(\..+?\.zip)$/';
$moved = 0;
$total = 0;
while (($filename = readdir($dh)) !== false) {
if (filetype("{$src}{$filename}") !== 'file') {
continue;
}
if (!preg_match($regex, $filename)) {
continue;
}
$total++;
$new_filename = preg_replace($regex, "$1$2", $filename);
$moved += (int)rename($src, "{$dst}{$new_filename}");
}
closedir($dh);
return [$moved, $total];
}
$srcDir = '/src/';
$dstDir = '/dst/';
$res = move_files($src, $dst);
if (!$res) {
// Error
}
list($moved, $total) = $res;
var_dump($moved, $total);
