How does PHP handle the casting of boolean values to integers and strings, and what implications does this have for output formatting?

When casting boolean values to integers in PHP, true is converted to 1 and false is converted to 0. When casting boolean values to strings, true is converted to "1" and false is converted to an empty string. This can have implications for output formatting when working with boolean values and needing them to be displayed as integers or strings in certain contexts.

$boolValue = true;

// Casting boolean value to integer
$intValue = (int)$boolValue;

// Casting boolean value to string
$stringValue = (string)$boolValue;

echo $intValue; // Output: 1
echo $stringValue; // Output: "1"
