How Can I Effectively Handle `dns_get_record()` Warnings in PHP?

Handling Warnings in PHP

You're encountering warnings when using dns_get_record() and seek to capture and handle these warnings. Try/catch blocks cannot handle warnings as they are not exceptions.

Best Practices for Warning Handling

There are several approaches you can take:

Set and Restore Error Handler:

Establish your custom error handler using set_error_handler(), which ignores errors, and then reset it with restore_error_handler(). This ensures that specific warnings are not reported.

Turning Errors into Exceptions:

Utilize set_error_handler() and ErrorException to convert all PHP errors into exceptions. This approach allows you to catch warnings using try/catch blocks.

Suppressing the Warning:

Suppress the warning using the @ operator and inspect the return value of dns_get_record(). However, this is generally not recommended as warnings should be handled rather than suppressed.

Recommended Approach:

Depending on your specific needs, the best practice may be to set an error handler or turn errors into exceptions. This allows you to handle warnings gracefully and take appropriate actions accordingly.
