What are the potential pitfalls of using is_int() in PHP for checking data types?

The potential pitfall of using is_int() in PHP for checking data types is that it will return false for integer values passed as strings. To solve this issue, you can use the is_numeric() function instead, which will correctly identify both integer values and integer values passed as strings. 

// Using is_numeric() instead of is_int() to correctly check for integer values
$value = "42";

if (is_numeric($value) && (int)$value == $value) {
    echo "Value is an integer.";
} else {
    echo "Value is not an integer.";
}
