Lewis,
First I would look at breaking out the tags:
// User: JohnDoe; age=32; nickname="Billy 'the' Kid"; haircolor=orange;
$string = 'User: JohnDoe; age=32; nickname="Billy \'the\' Kid";
haircolor=orange;';
$stringArray = preg_split('/;/', $string, -1, PREG_SPLIT_NO_EMPTY);
Then split by the = or :
// split by = or :
foreach ($stringArray as $item) {
list($tag, $element) = preg_split('/\:|\=/', $item, 1,
PREG_SPLIT_NO_EMPTY);
echo "$tag => $element<br />";
}
