This splits the string as you intended, I'm assuming you want the
headings kept with their respective information sections? I don't think
you can do that directly with preg_split, but if you do:

$Results = preg_split('/^\S+/m', $string, -1, PREG_SPLIT_DELIM_CAPTURE);

$Results will look something like:

$Results[0] = "heading1"
$Results[1] = "information1..."
$Results[2] = "heading2"
$Results[3] = "information2..."
etc.

Now all you need to do is concantenate $Results[0] with $Results[1],
$Results[2] with $Results[3], and so on.

Hope this helps,
Oli
