Php imap_fetchbody cannot get html link tag link

Question

I create emails by reading the script, it reads emails via imap, when I try to read the email body using imap_fetchbody, it shows only texts, but the email body has one link that seems not to be shown.

This is my code.

    $hostname = '{mail.test.com/notls}INBOX';
    $username = '[e-mail]';
    $password = 'testopw';

    /* try to connect */
    $inbox = imap_open($hostname,$username,$password) or die('Cannot connect to Email Server: ' . imap_last_error());
    /* grab emails */
    $emails = imap_search($inbox,'SEEN FROM "[e-mail]"');
if($emails) {

    /* put the newest emails on top */
    rsort($emails);
    /* for every email... */
    foreach($emails as $email_number) {
        /* get information specific to this email */                
       echo $message = imap_fetchbody($inbox,$email_number,1);
}
}

When I read email from the text of the email client here , there is a link, but when you read that with php it only displays text,

The email screen shot here is someone who knows what the cause of this problem is, or you need to change some settings to get a link with a URL. Thank you.

 From: Nathaniel Borenstein <[e-mail]> 
 To:  Ned Freed <[e-mail]> 
 Subject: Sample message 
 MIME-Version: 1.0 
 Content-type: multipart/mixed; boundary="simple 
 boundary" 

 This is the preamble.  It is to be ignored, though it 
 is a handy place for mail composers to include an 
 explanatory note to non-MIME compliant readers. 
 --simple boundary 

 This is implicitly typed plain ASCII text. 
 It does NOT end with a linebreak. 
 --simple boundary 
 Content-type: text/plain; charset=us-ascii 

 This is explicitly typed plain ASCII text. 
 It DOES end with a linebreak. 

 --simple boundary-- 
 This is the epilogue.  It is also to be ignored.
