How can one ensure that arrays are properly indexed and utilized in PHP scripts to avoid unexpected behavior?

To ensure that arrays are properly indexed and utilized in PHP scripts to avoid unexpected behavior, always start indexing arrays from 0, as PHP arrays are zero-indexed. Additionally, make sure to properly iterate over arrays using loops like foreach or for to access and manipulate array elements accurately. 

// Example of properly indexing and utilizing arrays in PHP

$fruits = array("apple", "banana", "orange");

// Using foreach loop to iterate over the array
foreach($fruits as $index => $fruit) {
    echo "Index: $index, Fruit: $fruit <br>";
}

// Accessing array elements using index
echo "First fruit: " . $fruits[0]; // Output: apple
