How does PHP handle different data types in switch case statements?

PHP handles different data types in switch case statements by using the "===" operator to check both the value and the data type of the expression in each case. This ensures that the comparison is strict and accurate, preventing unexpected behavior that can occur with loose comparisons.

$data = 1;

switch (true) {
    case $data === 1:
        echo "Integer 1";
        break;
    case $data === "1":
        echo "String 1";
        break;
    default:
        echo "Not matched";
}
