Syntax error or access violation: 1064 You have an error in your SQL syntax — PHP[PDO]

I try to Insert Multiple Records in my DB but give error when I use the third INSERT Statement
I need Help Plz.

I’ve looked through all the other StackOverflow (and google) posts with the same problem, but none seemed to address my problem.

I am using PDO and PHP.

My code:

 <?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "test";

try {
  $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
  // set the PDO error mode to exception
  $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

  // begin the transaction
  $conn->beginTransaction();
  // our SQL statements
  $conn->exec("INSERT INTO emp (emp_name, emp_address, emp_salary, join_date)
  VALUES ('John', 'Doe', '5000', '30.03.2022')");
  $conn->exec("INSERT INTO emp (emp_name, emp_address, emp_salary, join_date)
  VALUES ('Johny', 'Doeo', '50000', '30.05.2022')");
  $conn->exec("INSERT INTO emp (femp_name, emp_address, emp_salary, join_date)
  VALUES (Johnn', 'Doeoo', '500000', '30.06.2022)");

  // commit the transaction
  $conn->commit();
  echo "New records created successfully";
} catch(PDOException $e) {
  // roll back the transaction if something failed
  $conn->rollback();
  echo "Error: " . $e->getMessage();
}

$conn = null;
