How can understanding the difference between variable indexes and values impact the functionality of a PHP script?

Understanding the difference between variable indexes and values is crucial in PHP scripting as it directly impacts how data is accessed and manipulated within arrays. Variable indexes refer to the position or key within an array, while values are the actual data stored at those positions. Mixing up indexes and values can lead to errors in accessing or updating array elements, resulting in unexpected behavior in the script. 

// Example of correctly accessing array values using indexes
$fruits = array("apple", "banana", "orange");
$index = 1; // index to access
$value = $fruits[$index]; // accessing value at index 1
echo $value; // output: banana
