php - In PDO is there a difference in performance if a int is quoted as a string? -

is there difference in performance if integer bound string in prepared pdo query? in mysql queries work either if value bound int or string, there difference in performance, or pitfalls when doing that?

$pdo = new pdo(     "mysql:host={$host};port={$port};dbname={$dbname};charset=utf8",      $username,      $password ); $statement = $pdo->prepare("select * `table` `id` = :param");  // there performance difference between 2 rows below $statement->bindvalue(":param", 5); $statement->bindvalue(":param", 5, pdo::param_int);  $statement->execute(); 

is there difference between binding parameter , specifying type, or quoting string?

if want take method specify type faster not specify type , default type pdo::param_str.

if run 1 million time avarage followed:

• int type specified: 0.53 seconds ($stmt->bindvalue(":param", 5, pdo::param_int);)
• no type specified: 0.66 seconds ($stmt->bindvalue(":param", 5);)
• str type sepcified: 0.70 seconds ($stmt->bindvalue(":param", 5, pdo::param_str);)
