Sending an Email With MANDRILL

For the below function you would have to put a file “Mandrill.php” in the same folder as the PHP file you would be using to send emails.

function send_email($to_email,$subject,$message1)
{
	require_once 'Mandrill.php';
$apikey = 'XXXXXXXXXX'; //specify your api key here
$mandrill = new Mandrill($apikey);
 
$message = new stdClass();
$message->html = $message1;
$message->text = $message1;
$message->subject = $subject;
$message->from_email = "blog@smartwebcare.com";//Sender Email
$message->from_name  = "Smart Web Care";//Sender Name
$message->to = array(array("email" => $to_email));
$message->track_opens = true;
 
$response = $mandrill->messages->send($message);
}

In the above code you would have to specify your own api key that you get from your Mandrill account.

<?php
$to = "abc@smartwebcare.com";
$subject = "This is a test email";
$message = "Hello World!";
send_email($to,$subject,$message);

    //vars  
    $valid_files = array();  
    //if files were passed in...  
    if(is_array($files)) {  
        //cycle through each file  
        foreach($files as $file) {  
            //make sure the file exists  
            if(file_exists($file)) {  
                $valid_files[] = $file;  
            }  
        }  
    }  
    //if we have good files...  
    if(count($valid_files)) {  
        //create the archive  
        $zip = new ZipArchive();  
        if($zip->open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) {  
            return false;  
        }  
        //add the files

        //echo 'The zip archive contains ',$zip->numFiles,' files with a status of ',$zip->status;  
          
        //close the zip -- done!  
        $zip->close();  
          
        //check to make sure the file exists  
        return file_exists($destination);
