Question

I've got a string like...

"labour 18909, liberals 12,365,conservatives 14,720"

...and i'd like a regex which can get rid of any thousands separators so i can pull out the numbers easily. Or even a regex which could give me a tidy array like:

(labour => 18909, liberals => 12365, conservatives => 14720)

Oh i wish i had the time to figure out regexes! Maybe i'll buy one as a toilet book, mmm.

Answer 1

Two-liner. Will also get Independents:

preg_match_all('/([a-zA-Z]+)\s*([\d,]+)(?:,|$)/', $str, $matches);
$totals = array_combine($matches[1], $matches[2]);

/* total:
Array
(
    [labour] => 18909
    [liberals] => 12,365
    [conservatives] => 14,720
)
*/
