my string can be
new-york-10036
or
chicago-55036
the desired result is
new-york
chicago
and i basically want to remove all the string that come after the first dash - followed by a number
seems easy but i don't know how
You can use Negative Lookahead, like so:
(.+)(?=\-\d)
The regex reads: "get me everything that is not followed by exactly one dash and exactly one number after that".
Given the input new-york-10036
the regex is going to capture only new-york
. In PHP you can get the matched string with:
$string = 'new-york-10036';
$regex = '/(.+)(?=\-\d)/';
preg_match($regex, $string, $return);
echo $return[0] . "\n";
It outputs new-york
.
See the regex working here .
