PHP foreach loop

I'm trying to write a script but keep getting stuck.

I have a variable $message. I want to parse it. So that everything contained between * and * could be a different color. For example:

This is message * 1

Wouldn't be effected. But 

This is a *message* see how it works *again here*.

Would have message and again here in a different color.

$message = 'This is a *message* see how it works *again here*.';
$colorMessage =  preg_replace('/\*([^\*]+|[\w]+)\*/', "<span class='color2'>$0</span>", $message);

$output = preg_replace('/\*([^*]+)\*/', '<em>$1</em>', $message);

or

$output = preg_replace('/\*(.+?)\*/', '<em>$1</em>', $message);

With regexpes:

$in = 'This is a *message* see how it works *again here*.';
$out = preg_replace('/\*([^*]+)\*/', '<span class="color">$1</span>', $in);
print $out;

little faster than non-greedy matches.

I would suggest the use of preg_replace():

$message = preg_replace("#\*(.*?)\*#", "<span class=\"color-red\">\\1</span>", $message);

Use explode to split the string on the asterisks. After that, you can output each element in the array, with the right markup inbetween to change the color.

Something like this:

$parts = explode('*', $message);

$italic = false;
for ($part in $parts)
{
  if ($italic) 
    echo '<i>' . $part . '</i>';
  else 
    echo $part;

  $italic = !$italic;
}
