PHP：将文本插入到分隔符

Question

I have a bunch of chat logs that look like this:

name: some text
name2: more text
name: text
name3: text

I want to highlight the just the names. I wrote some code that should do it, however, I was wondering if there was a much cleaner way than this:

$line= "name: text";
$newtext = explode(":", $line,1);
$newertext = "<font color=red>".$newtext[0]."</font>:";
$complete = $newertext.$newtext[1];
echo $complete;

Looks fine, although you can save the temp variables:

$newtext = explode(":", $line,1);
echo "<font color=red>$newtext[0]</font>:$newtext[1]";

This might be faster or might not, you'd have to test:

echo '<font color=red>' . substr_replace($line, '</font>', strpos($line, ':') , 0);
