如何获取与特定值匹配的特定类型的行？

I want to get data from a table in my MySQL database.

  $linkID = mysql_connect($host, $user, $pass) or die("Could not connect to host."); 
  mysql_select_db($database, $linkID) or die("Could not find database."); 

 $search='flu';

  $query = mysql_query("SELECT * From ProviderDxCptCodes WHERE CodeType='CPT'");

   $rows = array();
   while($row = mysql_fetch_assoc($query)) {
   $rows[] = $row;
  }
  echo json_encode($rows);

I want this query to show me all CPT codes matching the search string flu. How can I do that?

Do you mean something like that?

SELECT * From ProviderDxCptCodes WHERE CodeType='CPT' AND name LIKE '%flu%';

$linkID = mysql_connect($host, $user, $pass) or die("Could not connect to host."); 
  mysql_select_db($database, $linkID) or die("Could not find database."); 


  $flu = "CPT";

  $query = mysql_query("SELECT * From ProviderDxCptCodes WHERE CodeType='%".mysql_real_escape_string($flu)."%'");

   $rows = array();
   while($row = mysql_fetch_assoc($query)) {
   $rows[] = $row;
  }
  echo json_encode($rows);
