How can the use of IDs in HTML forms affect the functionality of PHP scripts when handling multiple inputs?

When using IDs in HTML forms for multiple inputs, it is important to ensure that each input has a unique ID to avoid conflicts when processing the form data in PHP scripts. To solve this issue, you can use the name attribute in the HTML form to identify each input instead of relying solely on IDs. In PHP, you can access the form data using the $_POST superglobal array and referencing the input names. 

<form method="post">
  <input type="text" name="input1">
  <input type="text" name="input2">
  <input type="submit" name="submit">
</form>

<?php
if(isset($_POST['submit'])){
  $input1 = $_POST['input1'];
  $input2 = $_POST['input2'];

  // Process the form data as needed
}
?>
