如何在这个 email 的正文中添加第二个 email 地址？

Question

What is the correct way to add $email_2 to the body of this email?

$mail->addCC($email);

$mail->addCC($email_2);
    
/*$mail->addBCC('bcc@example.com');*/

//Body content
$body = "<p><strong>Hello, </strong>" . $email . " Your message was sent.

What I've tried:

 //Body content
$body = "<p><strong>Hello, </strong>" . $email . " ". $email_2 ." Your message was sent.

Answer 1

Your code is almost correct, you need to close the quote and add a semicolon at the end as well as a paragraph closing. Let's create a paragraph for each email:

$mail->addCC($email);

$mail->addCC($email_2);
    
/*$mail->addBCC('bcc@example.com');*/

//Body content
$body = "";

foreach ([$email, $email_2] as $current) {
    $body .= "<p><strong>Hello, </strong>" . $current . " Your message was sent.</p>";
}
