here's a horrid little bit of .... for you :)

EOD;
$coordRE = "(?:[ ]?[-+]?\\d+(?:\\.\\d+)?[ ]?)";
$coordsRE = "#(\\({$coordRE},{$coordRE}\\))#";
$matches = array();
preg_match_all($coordsRE, $testStr, $matches);
var_dump($testStr, $matches);
?>
preg_match_all($expression, "$string", $matches);
^-- why ? ...
are you wrapping the variable in double quotes?
This returns the correct strings (334,-53.44) and (111,222), but I'd like
all formats to work. Like (111, 222), ( 111 , 222 ), (111, 222 ), etc, etc.
How would I change my regex to accomplish this?
