copy file to every dir and subdir in path PHP - php

Question

I need a script to copy a file to every dir and subdir inside a specific folder.
Inside a folder called 'projects' i have several folders with several folders inside them (and so on), i need a script that checks if there is a specific file in that folder, if exist, then do nothing, if not, copy it.
I need to do this in php...
Can you help?

This would copy all files , all folders and its content .... from cunnrent directory to target .. using RecursiveDirectoryIterator and RecursiveIteratorIterator
echo "<pre>";
mkdirRecursive($target);
if (! is_writable($target)) {
echo "You don't have permission wo write to ", $target, PHP_EOL;
}
$it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir));
while ( $it->valid() ) {
if (! $it->isDot()) {
$name = $it->key();
$final = $target . str_replace($dir, "", $name);
if (! mkdirRecursive(dirname($final))) {
echo "Can Create Directory : ", dirname($final), PHP_EOL;
continue;
}
if (! #copy($name, $final)) {
echo "Can't Copy : ", dirname($final), PHP_EOL;
continue;
}
echo "Copied ", basename($name), " to ", dirname($final), PHP_EOL;
}
$it->next();
}
function mkdirRecursive($pathname, $mode = 0777) {
is_dir(dirname($pathname)) || mkdirRecursive(dirname($pathname), $mode);
return is_dir($pathname) || #mkdir($pathname, $mode);
}
