What are common pitfalls when trying to solve equations in PHP?

One common pitfall when solving equations in PHP is not properly handling division by zero errors. This can lead to unexpected results or errors in your code. To avoid this issue, always check for division by zero before performing the operation.

// Check for division by zero before performing the operation
$a = 10;
$b = 0;

if ($b != 0) {
    $result = $a / $b;
    echo "Result: " . $result;
} else {
    echo "Division by zero error.";
}
