Hi David,
Just to answer this question, I would probably use something like the
following pattern

I need to catch all instances of a coordinate in a give string. So far I
have this, which only works if the coordinate is in a certain format.
$string = (334,-53.44),(111,222);
$expression = '([(][-]?[0-9]*[.0-9]*?,[-]?[0-9]*[.0-9]*?[)])';
preg_match_all($expression, "$string", $matches);
