[SOLVED] Add a character inbetween

[briant]

I'm sure there's a function for this, I just don't know what it is.

 

In the database I have a 13 character number. I want to add a dash after the 3rd number.

 

948-3750279853

 

I tried wordwrap, that kind worked but it added a dash after every 3rd. number_format is a no. I was going to do a substr twice but that's kind of sloppy. There must be a better way.

 

Thanks for any help in advanced.

you can use substr to split it at a position and then put a dash in between

Another way to do it is with sscanf() and implode():

 

<?php
$str = '9483750279853';
$str = implode(sscanf($str, '%3s%10s'), '-');
?>
