How do negative numbers behave in PHP when comparing them?

When comparing negative numbers in PHP, it's important to remember that PHP uses signed integers for comparison. This means that negative numbers are considered less than positive numbers. To accurately compare negative numbers, you can use the abs() function to get the absolute value of the numbers before comparing them. 

$num1 = -5;
$num2 = -10;

if (abs($num1) < abs($num2)) {
    echo "num1 is less than num2";
} else {
    echo "num1 is greater than or equal to num2";
}
