What are the advantages of giving each array element an index when dealing with checkbox values and text inputs in PHP?

When dealing with checkbox values and text inputs in PHP, giving each array element an index allows us to easily loop through the values and process them. This is especially helpful when working with multiple checkboxes or text inputs with similar names. By assigning indexes to the array elements, we can access each value individually and perform operations on them accordingly. 

<form method="post">
  <input type="checkbox" name="checkbox_values[]" value="1"> Checkbox 1
  <input type="checkbox" name="checkbox_values[]" value="2"> Checkbox 2
  <input type="text" name="text_values[]" value="">
  <input type="text" name="text_values[]" value="">
  <input type="submit" name="submit" value="Submit">
</form>

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

  foreach($checkbox_values as $checkbox) {
    // Process checkbox values
    echo "Checkbox value: " . $checkbox . "<br>";
  }

  foreach($text_values as $text) {
    // Process text input values
    echo "Text value: " . $text . "<br>";
  }
}
?>
