What are the potential pitfalls of using a loop in the same PHP file for processing user input?

Using a loop in the same PHP file for processing user input can lead to potential issues such as increased complexity, decreased readability, and difficulty in debugging. To solve this problem, it is recommended to separate the processing logic into a separate file or function to improve code organization and maintainability. 

// Separate processing logic into a separate function

function processUserInput($input) {
    foreach ($input as $value) {
        // Processing logic here
    }
}

// Call the function with user input
$input = $_POST['input'];
processUserInput($input);
