how can able achieve in php.

php knows nothing json, convert array , use array_filter, , convert json. not super effecient, better trying regex. following:

$arr = json_decode($json, true); $res = array_filter($arr, function($val) {     return substr($val['name'],0,1) == 'b'; }); $newjson = json_encode($res);
