What does the error message "Division by zero" indicate in PHP code?

The error message "Division by zero" in PHP code indicates that there is an attempt to divide a number by zero, which is mathematically impossible. To solve this issue, you need to ensure that the denominator in your division operation is not zero. You can add a conditional check to prevent division by zero by verifying that the denominator is not zero before performing the division operation.

$numerator = 10;
$denominator = 0;

if ($denominator != 0) {
    $result = $numerator / $denominator;
    echo "Result: " . $result;
} else {
    echo "Division by zero is not allowed.";
}
