If I wanted to take a first name / last name string separated by a comma and change the order, how might I go about that?
last name, firstname
should be changed to
firstname lastname (without the comma)
Thanks.

Something like this would work:
string[] names = LastNameFirstName.Split(',');
string FirstNameLastName = names[1] + " " + names[0];

People should really say what language they are asking about rather then relying on people to look at their tags.

It's ok, I can still follow the logic in it. I think PHP has a split function that does the same thing. It's a start in the right direction, thanks!

split() uses a RegExp which is a bit overkill... explode() would be more effective.

Thanks Kane. Much appreciated. Gonna give you credit for the answer too. :)

This should do it.
$string = 'last,first';
list($last,$first) = explode( ",", $string );
echo $first . ' ' . $last;

You should probably use `explode(",", $string, 2)` just in case there is a 2nd comma.
too much php

If you wanted to get it done in a spiffy one-liner you could do this:
<?php
$name = "Smith, Dave";
echo implode(' ', array_reverse(explode(',', $name)));

You are adding unnecessary overhead to the equation for the sake of saving 1 line. This way is also harder for someone who hasn't seen it to figure out what it does. What is the advantage to this?

The question was neither: "How do I do X in the fastest way possible?", nor "How do I do X with the smallest memory footprint possible?". Thus, I provided a solution.

hobodave I didn't mean to offend I simply didn't understand why you would want to sacrifice efficiency and readability for the sake of one line. Sorry for coming across rude.

None taken. I apologize for my snippy retort. It's a programming style thing really. Would I do that in my own code? Maybe, maybe not. I'd definitely wrap it in a method though, and not worry about the inner-workings or performance of it until profiling time came. e.g. $foo->normalizeNameFirstLast('Smith, Dave'); I'm a big proponent of avoiding premature optimization. From a readability standpoint, you definitely have an argument though.

A:
$string = 'last , first';
list($last,$first) = preg_split("/\s+,\s+/",$string);
$s = preg_split("/[, ]/",$string);
print implode(" ", array($s[0], end($s)));
print implode(" ", array($last,$first));
print preg_replace("/(\w+)\s+,\s+(\w+)/","$2 $1", $string);
