Cita: Here is a function that will recursively copy a file into every directory within a specified directory, unless the directory is in an optional third parameter, an array with a list of directory names to skip. It will also print whether it copied each item it expected to.
NEW: Apparently, if you try to copy a file to itself in PHP, you end up with an empty file. To alleviate this, I added a fourth parameter, also optional, which is the number of levels to skip when copying files. The default is 0, which will only skip the directory specified in $dir, so that a call using the file's directory will work properly. I would not recommend calling this function with a directory higher up the tree than the file's.
Código PHP:
<?php
function copyintodir ($file, $dir, $skip = array(''), $level_count = 0) {
if (count($skip) == 1) {
$skip = array("$skip");
}
if (!@($thisdir = opendir($dir))) {
print "could not open $dir<br />";
return;
}
while ($item = readdir($thisdir) ) {
if (is_dir("$dir/$item") && (substr("$item", 0, 1) != '.') && (!in_array($item, $skip))) {
copyintodir($file, "$dir/$item", $skip, $level_count + 1);
}
}
if ($level_count > 0)
if (@copy($file, "$dir/$file")) {
print "Copied $file into $dir/$file<br />\n";
} else {
print "Could not copy $file into $dir/$file<br />\n";
}
}
}
?>
Oh mira mas info de esto por aqui :

Si haces funcionar un php asi como quieres, una vez que copia lo que quieres donde quieres, nomás lo agregas al CRONJOB y listo... desde yá, está ver si tu host/server lo soporta o lo permite.
