(?<=token=).*(?=;)

if (preg_match("/(token=)(.*?)(;|$)/i","user=asdasd; token=dwwewee; type=assdfs", $matches)) {    print_r($matches[2]);}

If the matching is successful, the results will be stored in the $ matches array. index 0 is the matching complete string, 1 is your first bracket, 2 is the second bracket, and so on. From your perspective, the value you need appears in the second bracket, so the value $ matches [2]

php//php5.6 echo explode('=',explode(';',$str)[1])[1];//dwwewee$arr = explode(';',"user=asdasd; token=dwwewee; type=assdfs");$arr2 = explode('=',$arr[1]);echo $arr2[1];//dwwewee
