Bulk Rename Files in a Folder - PHP - php

Question

I have 1000 images in a Folder, which has SKU# word in all the images. For examples
WV1716BNSKU#.zoom.1.jpg
WV1716BLSKU#.zoom.3.jpg
what i need to do is read all the filenames and rename it to the following
WV1716BN.zoom.1.jpg
WV1716BL.zoom.3.jpg
So remove SKU# from filename, is it possible in PHP to do bulk renaming ?

Answer 1

Yeah, just open the directory and create a loop to access all images and rename them, like:
<?php
if ($handle = opendir('./path/to/files')) {
while (false !== ($fileName = readdir($handle))) {
if($fileName != '.' && $fileName != '..') {
$newName = str_replace("SKU#","",$fileName);
rename('./path/to/files/'.$fileName, './path/to/files'.$newName);
}
}
closedir($handle);
}
?>

Answer 2

piece of cake:
foreach (array_filter(glob("$dir/WV1716B*.jpg") ,"is_file") as $f)
rename ($f, str_replace("SKU#", "", $f));
(or $dir/*.jpg if number doesn't matter)

Answer 3

The steps to completing this is pretty simple:
iterate over each file using fopen, readdir
for each file parse the file name into segments
copy the old file into a new directly called old (sanity reasons)
rename the root file top the new name.
A small example:
if ($handle = opendir('/path/to/images'))
{
/* Create a new directory for sanity reasons*/
if(is_directory('/path/to/images/backup'))
{
mkdir('/path/to/images/backup');
}
/*Iterate the files*/
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != "..")
{
if(!strstr($file,"#SKU"))
{
continue; //Skip as it does not contain #SKU
}
copy("/path/to/images/" . $file,"/path/to/images/backup/" . $file);
/*Remove the #SKU*/
$newf = str_replace("#SKU","",$file);
/*Rename the old file accordingly*/
rename("/path/to/images/" . $file,"/path/to/images/" . $newf);
}
}
/*Close the handle*/
closedir($handle);
}

Well, using iterators:
class SKUFilterIterator extends FilterIterator {
public function accept() {
if (!parent::current()->isFile()) return false;
$name = parent::current()->getFilename();
return strpos($name, 'SKU#') !== false;
}
}
$it = new SkuFilterIterator(
new DirectoryIterator('path/to/files')
);
foreach ($it as $file) {
$newName = str_replace('SKU#', '', $file->getPathname());
rename($file->getPathname(), $newName);
}
The FilterIterator basically filters out all non-files, and files without the SKU# in them. Then all you do is iterate, declare a new name, and rename the file...
Or in 5.3+ using the new GlobIterator:
$it = new GlobIterator('path/to/files/*SKU#*');
foreach ($it as $file) {
if (!$file->isFile()) continue; //Only rename files
$newName = str_replace('SKU#', '', $file->getPathname());
rename($file->getPathname(), $newName);
}

You can also use this sample:
$directory = 'img';
$gallery = scandir($directory);
$gallery = preg_grep ('/\.jpg$/i', $gallery);
// print_r($gallery);
foreach ($gallery as $k2 => $v2) {
if (exif_imagetype($directory."/".$v2) == IMAGETYPE_JPEG) {
rename($directory.'/'.$v2, $directory.'/'.str_replace("#SKU","",$v2));
}
}

Answer 6

$curDir = "/path/to/unprocessed/files";
$newdir = "/path/to/processed/files";
if ($handle = opendir($curDir))
{
//make the new directory if it does not exist
if(!is_dir($newdir))
{
mkdir($newdir);
}
//Iterate the files
while ($file = readdir($handle))
{
// invalid files check (directories or files with no extentions)
if($file != "." && $file != "..")
{
//copy
copy($curDir."/".$file, $newdir."/".$file);
$newName = str_replace("SKU#","",$file);
//rename
rename($newdir."/".$file, $newdir."/".$newName.".jpg");
}
}
closedir($handle);
}
