ta der.
been doing a bit more and ive discovered it is indeed possible to
shorten the code:
$string = ",viewport: {center: {lat: 57.138801,lng: -2.120481},span:
{lat: 0.002700,lng: 0.004975},mapType: null},overlays: {markers: [{id:
'A',lat: 57.138801,lng: -2.120481,image: '/mapfiles/arrow.png',icon:
function() { return parent.G_ADDR_ICON; },eid:
'ACPWRI2gLsqEswG1peiwDQ',inf";
$pattern = "/(center: {lat: )(-?[0-9]{1,3}\.[0-9]{6})(,lng:
)(-?[0-9]{1,3}\.[0-9]{6})/";
preg_match_all($pattern, $string, $matches, PREG_SET_ORDER);
print_r($matches);
Array
(
[0] => Array
(
[0] => center: {lat: 57.138801,lng: -2.120481
[1] => center: {lat:
[2] => 57.138801 -- bingo!
[3] => ,lng:
[4] => -2.120481 -- bingo!
)
)
however, the backreferencing would be good to have:
$pattern = "/(center: {lat: )(-?[0-9]{1,3}\.[0-9]{6})(,lng: )\2/";
but doesnt seem to work (ie i want to make a second use of
(-?[0-9]{1,3}\.[0-9]{6})
any ideas?
ta!
