[RESOLVED] Uppercase lowercase problem

itsrien

Hello all, I try to accomplish the following.
I have a string like: “volkswagen-golf-gti”
And I want it to change to: “Volkswagen Golf GTI” (last part completely uppercase)
I already have the following.

<?php

$var = 'volkswagen-golf-gti';
$var2 = ucwords(str_replace('-', ' ', $var));

echo $var2;

But this change it into: Volkswagen Golf Gti
And I want it to change in: Volkswagen Golf GTI

Is it even possible to accomplish this with php?

[man]ucwords/man will get you most of the way there, but the only way PHP will know that "GTI" should be all upper-case would be if you did an explicit search/replace on it, e.g. with [man]preg_replace/man.

I have some difficulties understanding preg_replace.
Right now I have the following code:

<?php
$var = 'volkswagen-golf-gti';
$var2 = ucwords(str_replace('-', ' ', $var));
$var2 = preg_replace("/\s+\S+$/e", "strtoupper('\\1')", $var2);
echo $var2;
?>

This code is only removing the last part of $var
so echo $var2 gives me "Volkswagen Golf"
How can I change the code so it select the last part of $var and make it uppercase with strtoupper? So the result of echo $var2; will be "Volkswagen Golf GTI"?
ps $var can be anything, not only volkswagen-golf-gti

I decided to see if I could do it all with one call to preg_replace() (just because 🙂 ), and this seems to work:

<?php
$var = 'volkswagen-golf-gti';
$regexp = array(
   '/-/' => ' ',
   '/.*/e' => 'ucwords("$0")',
   '/\b\S+$/e' => 'strtoupper("$0")'
);
$var2 = preg_replace(array_keys($regexp), $regexp, $var);
echo $var2;

I liked the above regex way of doing everything in one shot.

But if you want to keep things simple with no regex engine load, then try this

echo substr($var2, 0, $last_space+1).strtoupper(substr($var2,$last_space+1));

The answer of NogDog did the trick perfectly, I really like the idea of doing it all in one line.
It helped me a lot.
Thank you all for the great help and insights.
