What are the potential pitfalls of repeating code in PHP, as seen in the forum thread?

Repeating code in PHP can lead to maintenance issues, as any changes or updates will need to be applied in multiple places. This can also make the code harder to read and understand, increasing the likelihood of errors. To solve this issue, you can create reusable functions or classes to encapsulate the repeated code and call them when needed. 

// Reusable function to avoid repeating code
function calculateTotal($price, $quantity) {
    return $price * $quantity;
}

// Example of using the function
$total = calculateTotal(10, 5);
echo "Total: $total";
