What is the significance of using is_int() versus is_numeric() in the PHP script for checking data types?
The significance of using `is_int()` versus `is_numeric()` in PHP is that `is_int()` specifically checks if a variable is an integer, while `is_numeric()` checks if a variable is a number or a numeric string. If you want to ensure that a variable is a whole number without any decimal points, `is_int()` is the appropriate function to use.
// Using is_int() to check if a variable is an integer
$number = 42;
if (is_int($number)) {
echo "The variable is an integer.";
} else {
echo "The variable is not an integer.";
}
