keep it on the list please.
and you still didn't answer the question :-)

....and also from your code:
$string = (334,-53.44),(111,222);
^-- er what is this 'string' about?

ah but they were not valid code - which can confuse matters.
try to post code that runs if you can (i.e. test if you're providing
a testcase) .. i guess you have to kind of flip that argument inside
out when it comes to enquiring whether something might be a bug -
there is still testing involved tho.

have you ever used 'php -r' - it's brilliant - especially when you
fund out how easy it is to cut and paste into a bash[-like] shell
(probably using Putty if/when your on windows). be ware of
single quotes.

maybe my regexp is not only bad but also wrong [for
grepping coordinates in a 'any' variation of '( 123 ,-45.78)' ] ?
$coordRE = "(?:[ ]?[-+]?\\d+(?:\\.\\d+)?[ ]?)";
$coordsRE = "#(\\({$coordRE},{$coordRE}\\))#";
var_dump($coordRE, $coordsRE);
