What are the potential pitfalls of spreading form processing functions across multiple files in a PHP application?

Spreading form processing functions across multiple files in a PHP application can lead to confusion and difficulty in managing the codebase. It can make it harder to track down and update form processing logic, as it is scattered in different files. To solve this issue, consolidate all form processing functions into a single file dedicated to handling form submissions. 

// form_processing.php

function processForm1() {
  // Form processing logic for form 1
}

function processForm2() {
  // Form processing logic for form 2
}

// Include this file in your main application file
include 'form_processing.php';

// Call the appropriate form processing function based on the form submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
  if (isset($_POST['form1_submit'])) {
    processForm1();
  } elseif (isset($_POST['form2_submit'])) {
    processForm2();
  }
}
