A PHP Competition

OK, here is the competition:

Write the shortest piece of PHP code to convert:
Lorem_ipsum_dolor_sit amet,_consectetur_adipisicing_elit

Into this:
Lorem_Ipsum_Dolor_Sit amet,_Consectetur_Adipisicing_Elit

There is no prize other than I will write a post about you
Leave a comment.

Update:
Chris wrote a perfectly working line of code for the first string I posted, but you will have to write one that will still work if there is a space in one of the words. I fixed the example.

Chris, your version is great but what if there was a space in one the words?

Comment
Boban:

I just modified a bit Cris`s solution:
echo str_replace(` 1 `,`_`,ucwords(str_replace(`_`,` 1 `,`Lorem_ipsum_dolor_sit_amet,_consectetur_adipisicing_elit`)));

Codehead:

Boban, if you look closer, it has a space in the middle of it:
Lorem_ipsum_dolor_sit amet,_consectetur_adipisicing_elit

amet, shouldn’t be capitalized:
Lorem_Ipsum_Dolor_Sit amet,_Consectetur_Adipisicing_Elit

Yours will capitalize amet…

Boban:

I`m sorry, it is completely my fault, i didn’t see that. Here is a solution:

$arr1 = array(‘ 2′,’ 1 ‘);
$arr2 = array(‘ ‘,’_');
echo str_replace($arr1,$arr2,ucwords(str_replace($arr2,$arr1,’Lorem_ipsum_dolor_sit amet,_consectetur_adipisicing_elit’)));

I came up with a better solution:

echo preg_replace(‘/_(\w)/e’,”_.strtoupper(\\1)”,’Lorem_ipsum_dolor_sit amet,_consectetur_adipisicing_elit’);

chris:

echo(str_replace(Array(” “,”|”),Array(“_”,” “),ucwords(str_replace(Array(” “,”_”),Array(“|”,” “),”Lorem_ipsum_dolor_sit amet,_consectetur_adipisicing_elit”))));

That’s fine Chris, good solutions, hoping to see more

How about this:

$string = ‘Lorem_ipsum_dolor_sit amet,_consectetur_adipisicing_elit’;
$words = explode(‘_’,$string);
foreach($words as $word) {
$wordarray[] = ucfirst($word).’_';
}
$string = rtrim(implode($wordarray),’_');
echo $string;

GK:

echo preg_replace(‘/_([a-z])/e’, ‘strtoupper(“_$1″)’, ‘Lorem_ipsum_dolor_sit amet,_consectetur_adipisicing_elit’) . “\n”;

Comment
Baz:

$s1 = ‘Lorem_ipsum_dolor_sit amet,_consectetur_adipisicing_elit’;
$ss = str_split($s1);foreach($ss as $k=>$v){if($v==’_'){$ss[$k+1]=strtoupper($ss[$k+1]);}}
echo implode(”,$ss);

Not sure how old this post is but thought I would chip in with my little suggestion:

echo mb_convert_case(‘Lorem_ipsum_dolor_sit amet,_consectetur_adipisicing_elit’,MB_CASE_TITLE,’UTF-8′);
