Why is it recommended to initialize variables as strings in PHP for comparison purposes?

When comparing variables in PHP, it's important to ensure that they are of the same type to avoid unexpected results. By initializing variables as strings, you can ensure that they are compared as strings, regardless of their original type. This can prevent issues such as type coercion and unintended comparisons. 

// Initialize variables as strings for comparison purposes
$variable1 = "10";
$variable2 = "5";

// Compare the variables as strings
if ($variable1 === $variable2) {
    echo "Variables are equal.";
} else {
    echo "Variables are not equal.";
}
