+/**
+ * Translates a number to a short alhanumeric version
+ *
+ * Translated any number up to 9007199254740992
+ * to a shorter version in letters e.g.:
+ * 9007199254740989 --> PpQXn7COf
+ *
+ * specifiying the second argument true, it will
+ * translate back e.g.:
+ * PpQXn7COf --> 9007199254740989
+ *
+ * this function is based on any2dec && dec2any by
+ * fragmer[at]mail[dot]ru
+ * see: http://nl3.php.net/manual/en/function.base-convert.php#52450
+ *
+ * If you want the alphaID to be at least 3 letter long, use the
+ * $pad_up = 3 argument
+ *
+ * In most cases this is better than totally random ID generators
+ * because this can easily avoid duplicate ID's.
+ * For example if you correlate the alpha ID to an auto incrementing ID
+ * in your database, you're done.
+ *
+ * The reverse is done because it makes it slightly more cryptic,
+ * but it also makes it easier to spread lots of IDs in different
+ * directories on your filesystem. Example:
+ * $part1 = substr($alpha_id,0,1);
+ * $part2 = substr($alpha_id,1,1);
+ * $part3 = substr($alpha_id,2,strlen($alpha_id));
+ * $destindir = "/".$part1."/".$part2."/".$part3;
+ * // by reversing, directories are more evenly spread out. The
+ * // first 26 directories already occupy 26 main levels
+ *
+ * more info on limitation:
+ * - http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/165372
+ *
+ * if you really need this for bigger numbers you probably have to look
+ * at things like: http://theserverpages.com/php/manual/en/ref.bc.php
+ * or: http://theserverpages.com/php/manual/en/ref.gmp.php
+ * but I haven't really dugg into this. If you have more info on those
+ * matters feel free to leave a comment.
