Last word of a string UpperCase

[itsrien]

Hello all, I try to accomplish the following.

I have a string like: “volkswagen-golf-gti” **

And I want it to change the string into:

“Volkswagen Golf GTI” (last part completely uppercase)

 

But I have some difficulties understanding preg_replace.

Right now I have the following code:

 

<?php 
$string = 'volkswagen-golf-gti'; 
$string2 = ucwords(str_replace('-', ' ', $string)); 
$string2 = preg_replace("/\s+\S+$/e", "strtoupper('\\1')", $string2); 
echo $string2; 
?>

   

Without line 4 enabled, the result of the echo $string2 is:

Volkswagen Golf Gti (is wrong, last part is not completely uppercase)

 

With line 4 enabled, the last part of the $string is removed

so echo $string2 gives me :

Volkswagen Golf

How can I change the code so it select the last part of $string2 and makes that part uppercase? So the result of echo $string2; will be:

Volkswagen Golf GTI

 

** $string can be anything, not only volkswagen-golf-gti

Not tested but...

 

$string = 'volkswagen-golf-gti';
$my_arrray = explode("-", $string);
$my_count = count($my_array);
$my_last = $my_count -1;
$last_word = strtoupper($my_array[$my_last]);
$my_array[$my_last] = $last_word;
$i=0;
$new_string = "":
while($i <$my_count) [
$new_string = $new_string . " " . $my_array[$i];
$i++;
}
echo $new_string;

$string2 = preg_replace('/([^ ]+)$/e', 'strtoupper("\\1")', ucwords(str_replace('-', ' ', $string)));

// or

// tried to get it in one line but having a brain cramp:
$string2 = array_map('ucfirst', explode('-', $string));
array_push($string2, strtoupper(array_pop($string2)));
$string2 = implode(' ', $string2);

Thanks you NoDog for providing me the solution, and solving my problem. The following code, did do the trick for me.

<?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;
?>
