发送多封电子邮件失败的php邮件[重复]

I want to send the email to two emails in one time, the first one to office@example.com the second one to guest who fill the form. Here my code

$email_to = "$c[email]"; 
$email_toko="office@example.com";
$subjek="**The Bandha Hotel** – Request for Pricing Submitted";

$dari = "From: {$email_toko}
"
      . "MIME-Version: 1.0
"
      . "Reply-To: {$email_to}
"
      . "Content-type: text/html; charset=iso-8859-1
"
      . 'X-Mailer: PHP/' . phpversion();
mail($email_to,$subjek,$pesan,$dari);
mail($email_toko,$subjek,$pesan,$dari);

but the email just send to $email_toko or just go to office@example.com. So the guest doesn't receive the email.help me please

First thing is that you can add Multiple recipients in mail() as below.

// Multiple recipients
$to = 'johny@example.com, sally@example.com'; // note the comma

In your code you are sending email separately to both of your address. mail() function returns Boolean if mail send or fail so you can check the by dumping response of your mail function as below.

$mailRes = mail($email_to,$subjek,$pesan,$dari);
var_dump($mailRes);

Also enable error reporting during development mode its helpful.
