What are some best practices for handling arrays and loops in PHP to avoid collisions and improve code readability?

Issue: To avoid collisions and improve code readability when handling arrays and loops in PHP, it is best practice to use clear and descriptive variable names, properly initialize arrays before using them, and avoid modifying arrays within loops to prevent unexpected behavior. 

// Example of best practices for handling arrays and loops in PHP

// Initialize an array with clear and descriptive variable names
$numbers = [1, 2, 3, 4, 5];

// Loop through the array using a foreach loop
foreach ($numbers as $number) {
    // Perform operations on each element without modifying the original array
    echo $number . "<br>";
}
