Convert php code to suitable snippet for string manipulation

Hi Guys,
How do I convert the below so that it works as a snippet in Revo?

			
<?php
$Sentence = "[[*pagetitle]]";
$Words = explode(" ", $Sentence);
$WordCount = count($Words);
$NewSentence = '';
for ($i = 0; $i < $WordCount; ++$i) {
    if ($i < 1) {
        $NewSentence .= '<strong>' . $Words[$i] . '</strong> ';
    } else {
        $NewSentence .= $Words[$i] . ' ';
    }
}
echo $NewSentence;

Its supposed to bold the first word in a sentence but when used in a Revo template it bolds all words. If I use it standalone as boldword.php it works fine. Not quite sure how to adjust the code to fulfill these requirements: http://rtfm.modx.com/revolution/2.x/developing-in-modx/basic-development/snippets#Snippets-ReadingValuesinyourSnippets
Using return instead of echo also doesn't work.

Thanks

You need to use $modx->resource->get('pagetitle') in a snippet's code rather than the MODX tag.

Here's a slightly different way:

<?php
$sentence = $modx->resource->get('pagetitle');
$words = explode(" ", $sentence);
$newSentence = '<strong> ';
$strongClosed = false;
foreach ($words as $word) {
    $newSentence .=  $word . ' ';
    if (! $strongClosed) {
        $newSentence .=  . '</strong> ';
        $strongClosed = true;
    } 
}
echo $newSentence;

I'm assuming that you don't really need a wordcount and I changed the variable names to conform with the typical PHP convention of having variable names start with a lowercase letter. My apologies if you use a different scheme.

Just to throw an alternative in, you could use a regular expression:

<?php
$sentence = $modx->resource->get('pagetitle');
$sentence = preg_replace('/^([^\b].*?\b)/', '<strong>$1</strong>', $sentence);
echo $sentence;

I suspect that the words in your pagetitles are separated by something other than spaces, so the code is treating the whole pagetitle as a word.

Try this:

$sentence = $modx->resource->get('pagetitle');
$words = explode(" ", $sentence);
$output = '<pre>' . print_r($words, true), '</pre>';
return $output;
