How can the correct comparison operator be used to ensure accurate validation in PHP scripts?

When validating data in PHP scripts, it's important to use the correct comparison operator to ensure accurate validation. For example, using '==' for comparing values can lead to unexpected results due to type coercion. Instead, using '===' will compare both the value and the data type, providing a more accurate validation.

// Incorrect comparison using '=='
$value = "10";
if ($value == 10) {
    echo "Values match";
} else {
    echo "Values do not match";
}

// Correct comparison using '==='
$value = "10";
if ($value === 10) {
    echo "Values match";
} else {
    echo "Values do not match";
}
