How to Embed Images in HTML Email
Sending HTML emails with embedded images can be challenging. Many solutions rely on external resources, which can cause images to fail to load due to spam filters or email client restrictions.
To overcome these issues, consider using a reliable library such as PHPMailer. Let's explore how to use PHPMailer to embed images:
PHPMailer's documentation provides excellent guidance on displaying embedded (inline) images. It recommends using the AddEmbeddedImage function:
<code class="php">$mail->AddEmbeddedImage(filename, cid, name);</code>
where:
- filename is the path to the image file
- cid is the Content ID used to link the image in the HTML email
- name is the filename that will be displayed
For example:
<code class="php">$mail->AddEmbeddedImage('my-photo.jpg', 'my-photo', 'my-photo.jpg ');</code>
To incorporate the embedded image into the HTML email, insert an img tag with the src attribute set to the cid value:
<code class="html"><img src="cid:my-photo" alt="my-photo" /></code>
Here's a complete code example:
<code class="php">require_once('../class.phpmailer.php');
$mail = new PHPMailer(true);
$mail->IsSMTP();
try {
$mail->Host = "mail.yourdomain.com";
$mail->Port = 25;
$mail->SetFrom('from@example.com', 'From Name');
$mail->AddAddress('to@example.com', 'To Name');
$mail->Subject = 'PHPMailer Test';
$mail->AddEmbeddedImage("rocks.png", "my-attach", "rocks.png");
$mail->Body = 'Your <b>HTML</b> with an embedded Image: <img src="cid:my-attach"> Here is an image!';
$mail->Send();
} catch (phpmailerException $e) {
echo $e->errorMessage();
} catch (Exception $e) {
echo $e->getMessage();
}</code>
This code constructs the HTML email with the embedded image and sends it using SMTP. You can adapt this example to send emails in other ways or use different methods provided by PHPMailer, such as CreateBody to retrieve the message content and send it manually.

What are the best practices for writing clean and maintainable PHP code?
Jun 24, 2025 am 12:53 AM
The key to writing clean and easy-to-maintain PHP code lies in clear naming, following standards, reasonable structure, making good use of comments and testability. 1. Use clear variables, functions and class names, such as $userData and calculateTotalPrice(); 2. Follow the PSR-12 standard unified code style; 3. Split the code structure according to responsibilities, and organize it using MVC or Laravel-style catalogs; 4. Avoid noodles-style code and split the logic into small functions with a single responsibility; 5. Add comments at key points and write interface documents to clarify parameters, return values ??and exceptions; 6. Improve testability, adopt dependency injection, reduce global state and static methods. These practices improve code quality, collaboration efficiency and post-maintenance ease.

How do I use page caching in PHP?
Jun 24, 2025 am 12:50 AM
PHP page caching improves website performance by reducing server load and speeding up page loading. 1. Basic file cache avoids repeated generation of dynamic content by generating static HTML files and providing services during the validity period; 2. Enable OPcache to compile PHP scripts into bytecode and store them in memory, improving execution efficiency; 3. For dynamic pages with parameters, they should be cached separately according to URL parameters, and avoid cached user-specific content; 4. Lightweight cache libraries such as PHPFastCache can be used to simplify development and support multiple storage drivers. Combining these methods can effectively optimize the caching strategy of PHP projects.
