简单的sendmail代码上的php语法错误

Question

所以Dreamweaver告诉我,我在第5,8,10和12行有语法错误.但我不明白为什么？

<?php
if(isset($_POST['submit'])) (
    $msg = 'Name: ' .$_POST['FirstName'] .$_POST['LastName'] ."\n" 
    .'Email: ' .$_POST['Email'] ."\n" 
    .'Message: ' .$_POST['Message'];
    mail('email@me.com', 'Message from website', $msg);
    header('location: contact-thank-you.php');
)
else (
header('location: contact.php');
exit(0);
)
)       
?>

Answer 1

使用:

if () {
  ....
} else {
  ....
}

other than

if () (
  ....
) else (
  ....
)
