How can debugging techniques be used to identify the source of a "Cannot redeclare" error in PHP code?

When encountering a "Cannot redeclare" error in PHP, it typically means that a function or class has been declared more than once in the code. To identify the source of this error, you can use debugging techniques such as checking for duplicate function or class declarations, ensuring that files are included only once, and using namespaces to prevent naming conflicts. 

// Example of using namespaces to prevent "Cannot redeclare" error
namespace MyNamespace;

// Check if the function exists before declaring it
if (!function_exists('myFunction')) {
    function myFunction() {
        // Function logic here
    }
}
