What are some alternatives to including PHP scripts on external sites, such as using img tags or iFrames?

When including PHP scripts on external sites, security concerns may arise due to the execution of potentially harmful code. To address this, one alternative is to use img tags or iFrames to display content from the external site without executing PHP scripts directly. This can help mitigate security risks while still allowing for the integration of dynamic content.

// Example of using an img tag to display content from an external site
echo '<img src="https://external-site.com/image.jpg" alt="External Image">';

// Example of using an iFrame to display content from an external site
echo '<iframe src="https://external-site.com/embedded-content" width="500" height="300"></iframe>';
