 * I’m trying to figure out how i can use one or more regular expressions to format
   a random $ number with 6-7 digits..
    e.g.
 * $606782 -> $606 782
    $300000 -> $300 000 $1237339 -> $1 237 339

 * Assuming you’re doing this in PHP, you could use `number_format()` or maybe even`
   money_format()`

 * If you’re using PHP the functions I mentioned do not require regex knowledge.

 * I’m using a regex search and replace plugin, but if you have a another solution?
   I know nothing about php and regex unfortunately. 🙁

 * If you really want a regex solution, and you only want to change numbers with
   6 or 7 digits, try something like:
 *     ```
       $string = preg_replace(array('(\d\d\d)(\d\d\d)','(\d)(\d\d\d)(\d\d\d)'), array('$1 $2','$1 $2 $3'), $string);
       ```
   
 * If you can remove the money ($) character, **number_format** is a much better
   solution since it will work with any size number.
