¿Cómo leer un correo gmail con IMAP en una app de Yii?1

Hola, qué tal, tengo una gran duda, me pasaron la siguiente función para leer correos electrónicos:

public function actionLeerCorreo(){

		set_time_limit(4000); 
		 
		// Connect to gmail
		$imapPath = '{imap.gmail.com:993/imap/ssl}INBOX';
		$username = 'mesa.ayuda@gmail.com';
		$password = 'mesaayuda--123';
		 
		// try to connect 
		$inbox = imap_open($imapPath,$username,$password) or die('Cannot connect to Gmail: ' . imap_last_error());
		 
		   /* ALL - return all messages matching the rest of the criteria
		    ANSWERED - match messages with the \\ANSWERED flag set
		    BCC "string" - match messages with "string" in the Bcc: field
		    BEFORE "date" - match messages with Date: before "date"

		    SINCE "date" - match messages with Date: after "date"

		// search and get unseen emails, function will return email ids
		$emails = imap_search($inbox,'UNSEEN');
		 
		$output = '';
		 
		foreach($emails as $mail) {
		    
		    $headerInfo = imap_headerinfo($inbox,$mail);
		    
		    $output .= $headerInfo->subject.'<br/>';
		    $output .= $headerInfo->toaddress.'<br/>';
		    $output .= $headerInfo->date.'<br/>';
		    $output .= $headerInfo->fromaddress.'<br/>';
		    $output .= $headerInfo->reply_toaddress.'<br/>';
		    
		    $emailStructure = imap_fetchstructure($inbox,$mail);
		    
		    if(!isset($emailStructure->parts)) {
		         $output .= imap_body($inbox, $mail, FT_PEEK); 
		    } else {
		        //    
		    }
		   echo $output;
		  // $output = '';
		}
		 
		// colse the connection
		imap_expunge($inbox);
		imap_close($inbox);

}

Necesito hacer que en mi vista aparezcan todos los datos del correo. ¿Cómo lo hago? (Por cierto, soy principiante)
