Answer 1

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);
}
