Truth be told I don't know anything about regex. I threw together an example of how I think I can step though a string to do this.

$actions = array();
$done = false;
while (!$done) {
$start = strpos($content, "[");
$end = strpos($content, "]");
$equal = strpos($content, "=");
$key = "";
$value = "";
if ($equal != false && $equal > $start && $equal < $end) {
$key = substr($content, $start + 1, $equal - $start);
$value = substr($content, $equal + 1, $end - $equal);
if (array_key_exists($key, $actions)) {
if (is_array($actions[$key])) {
$actions[$key][] = $value;
}else{
$existing_value = $actions[$key];
$actions[$key] = array ($existing_value, $value);
}
}else{
$actions[$key] = $value;
}
str_replace("[" . $key . "=" . $value . "]", "", $content, 1);
}else{
$key = substr($content, $start + 1, $end - $start);
$actions[$key] = true;
str_replace("[" . $key . "]", "", $content, 1);
}
if ($start == false || $end == false) {
$done = true;
}
}

This should...in theory find the first set of brackets if there is a "=" it should separate out the part before the = as the key and the part after as the value, add to an array, using a sub array if the same key is duplicated with different values. If not it will just store the text as the key with a value of true. It will then replace the full sub-string from [ to ] with null effectively removing it then search for the next one until it finds no more bracket sets.

Any feedback, ideas on a better implementation?
