Fetch records from a two-dimensional array based on conditions

There is an array $point_history (as shown below), take out the array row with user_id = 3.
The code is as follows:
//Your array
 $point_history = array(
 array("id"=>1,"user_id"=>1,"points"=>2),
 array("id" =>2,"user_id"=>3,"points"=>2),
 array("id"=>3,"user_id"=>3,"points"=>2),
 array("id"=>4,"user_id"=>3,"points"=>2),
 );
 for($row = 0;$row  if($point_history[$row]["user_id"] == 3){
 //$new is a new array used to receive user_id=3.
 $new[] = $point_history[$row];
 }
 }
 //Output the new array.
 for($row = 0;$row  print_r($new[$row]);
 echo "";
 }
