What are the best practices for handling output redirection in PHP to avoid naming collisions and ensure seamless integration with existing code?

When handling output redirection in PHP to avoid naming collisions and ensure seamless integration with existing code, it is best to use unique names for output variables and functions to prevent conflicts. Additionally, utilizing namespaces can help organize and encapsulate code to avoid clashes with other parts of the application.

<?php

namespace MyNamespace;

// Define a unique output variable
$output = "Hello, world!";

// Create a function with a unique name for output redirection
function redirectOutput() {
    // Redirect output logic here
}

// Example usage of the output variable and function
echo $output;
redirectOutput();

?>
