• How do I extract query parameters from a URL string in PHP? 3 answers

I have got the following string

http://www.domain.com/map.aspx?isTrafficAlert=true&lat=51.529900&lon=-0.785384

I need to extract lat and lon from this string.

I got lat=51.529900 and lon=-0.785384 using the following code

$str = "http://www.domain.com/map.aspx?isTrafficAlert=true&lat=51.529900&lon=-0.785384";
list(,$lat,$lon) = explode("&",$str);

But then can't get the number.

Any help is highly appreciated. Thanks in advance.

You can use parse_str along with parse_url like as

parse_str(parse_url($str, PHP_URL_QUERY), $latlon);
echo $latlon['lat'];
echo $latlon['lon'];
