What is CORS and how do I implement it in PHP?

CORS stands for Cross-Origin Resource Sharing. It's a security feature that allows or restricts resources on a web page to be requested from another domain outside the domain from which the first resource was served. To implement CORS in PHP, you can use middleware to set the appropriate headers.

What headers do I need to set for CORS?

You typically need to set the 'Access-Control-Allow-Origin' header to specify which domains are allowed to access your resources. You might also need 'Access-Control-Allow-Methods' and 'Access-Control-Allow-Headers' depending on your requirements.

Can you show me a simple example of CORS middleware in PHP?

Sure! Here's a simple example:

function cors() {
    header('Access-Control-Allow-Origin: *');
    header('Access-Control-Allow-Methods: GET, POST, OPTIONS');
    header('Access-Control-Allow-Headers: Content-Type, Authorization');
}

cors();
