当正文中有URL时，PHP邮件将不会发送[关闭]

I'm trying to send this html email and for some reason it won't send when there's a link in the body. The only difference between these two files seems to be that one has a link in the body. If I put the same thing in the subject it sends fine.

Works perfectly:

//mail body and subject
$mail_body = "Test Email with no link.";
$subject = "Test email with no link";

//recipient
$recipient = "myemail@mydomain.com";

//headers to send HTML email
$header = "MIME-Version: 1.0
" ;
$header = $header . "Content-Type: text/html; charset="\iso-8859-1\"
";
$header = $header . 'From: admin@test.com';

//send the message
mail($recipient, $subject, $mail_body, $header) or die('mail could not be sent'); //mail command :)
echo('Good Test');

Does Not work:

//mail body and subject
$mail_body = "Test Email with link. <a href=\"http://www.google.com\">google</a>";
$subject = "Test email with with link. ";

//recipient
$recipient = "myemail@mydomain.com";

//headers to send HTML email
$header = "MIME-Version: 1.0
" ;
$header = $header . "Content-Type: text/html; charset=\"iso-8859-1\"
";
$header = $header . 'From: admin@test.com';

//send the message
mail($recipient, $subject, $mail_body, $header) or die('mail could not be sent'); //mail command :)
echo('Bad Test');

You need to escape the quotes in your e-mail address. Check the backslashes:

$mail_body = "Test Email with link. <a href=\"http://www.google.com\">google</a>";

It looks like the href in your $mail_body has an unescaped double quote. Have you tried:

$mail_body = "Test Email with link. <a href=\"http://www.google.com\">google</a>";

Note the backslashes.

You have 4 quotes (") in the $mail_body tag - it tries to assign the information between the first 2 quotes only, then expects something like a semi colon (;) at the end or append operator (.), when it doesn't see one of these it doesn't know what to do. It also should be a problem in the 2nd header ($header= $header . "Content-Type: text/html; charset="iso-88598-1" ";

The simplest way to do this is:

Change the following:

FROM THIS:

$mail_body = "Test Email with link. <a href="http://www.google.com">google</a>";

TO THIS:

$mail_body = "Test Email with link. <a href=\"http://www.google.com\">google</a>";

FROM THIS: $header = $header . "Content-Type: text/html; charset="iso-8859-1" "; TO THIS: $header = $header . "Content-Type: text/html; charset=\"iso-8859-1\" ";
