What are some best practices for encouraging users to test their own code before asking for help on a PHP forum?

One best practice for encouraging users to test their own code before asking for help on a PHP forum is to thoroughly explain the issue they are facing or how to potentially solve it. This can help users understand the problem better and potentially find a solution on their own. Additionally, providing a complete PHP code snippet that implements the fix can serve as a helpful example for users to test and troubleshoot their code before seeking assistance on the forum.

// Example code snippet to demonstrate how to fix a common PHP error
$variable = "Hello World";
echo $variable;
