How to update a PHP email function to use Mailgun's API?

I’m trying to switch my PHP email function to work with Mailgun’s API. I currently have a function that sends emails using the PHP mail() function. I found Mailgun’s documentation that demonstrates sending emails via an HTTP POST request, but I need help merging that code with my existing function.

Here’s a simplified version of my current function:

function sendEmail($to, $subj, $msg, $shortcodes = '', $bcc = false) {
    // ... process variables and headers ...
    return mail($to, $subj, nl2br(html_entity_decode($msg)), $headers, $optionalParams);
}

I attempted to add some cURL code similar to the following:

$ch = curl_init();
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
    'from' => 'Webmaster <[email protected]>',
    'to' => $to,
    'subject' => $subj,
    'text' => $msg
));

However, this didn’t work as expected. I’m fairly new to both PHP and working with APIs. Can someone show me how to combine these approaches or point me to an example that replicates this functionality? Thanks for your help!

Having worked with Mailgun’s API extensively, I can offer some insights. While the PHP SDK is a solid choice, you can also use Guzzle for a more lightweight approach. Here’s a simplified version that should work:

function sendEmail($to, $subj, $msg, $shortcodes = '', $bcc = false) {
    $client = new GuzzleHttp\Client();
    $response = $client->request('POST', 'https://api.mailgun.net/v3/your-domain.com/messages', [
        'auth' => ['api', 'your-api-key'],
        'form_params' => [
            'from' => 'Webmaster <[email protected]>',
            'to' => $to,
            'subject' => $subj,
            'text' => $msg
        ]
    ]);

    return $response->getStatusCode() == 200;
}

This method gives you more control over the HTTP request while still being relatively straightforward. Remember to handle errors and consider adding retry logic for robustness.

hey there! i’ve used mailgun before and it’s pretty sweet. here’s a quick way to update ur function:

function sendEmail($to, $subj, $msg, $shortcodes = '', $bcc = false) {
    $mg = new Mailgun('your-api-key');
    $domain = 'your-domain.com';
    
    return $mg->sendMessage($domain, [
        'from' => 'Webmaster <[email protected]>',
        'to' => $to,
        'subject' => $subj,
        'text' => $msg
    ]);
}

easy peasy! just make sure u have the mailgun library installed first. good luck!

I’ve been down this road before, and switching to Mailgun’s API can be a game-changer for email deliverability. Here’s what worked for me:

First, you’ll need to install Mailgun’s PHP SDK using Composer. Once that’s done, here’s a basic example of how you can modify your function:

function sendEmail($to, $subj, $msg, $shortcodes = '', $bcc = false) {
    $mg = Mailgun::create('your-api-key');
    $domain = 'your-domain.com';

    $result = $mg->messages()->send($domain, [
        'from'    => 'Webmaster <[email protected]>',
        'to'      => $to,
        'subject' => $subj,
        'text'    => $msg,
    ]);

    return $result->getId(); // Returns message ID on success
}

This approach is much cleaner than using cURL directly. It handles authentication and request formatting for you. Just remember to handle exceptions and you’ll be good to go. Hope this helps!
