How is it possible to cast types in PHP?

In PHP, types can be cast using explicit typecasting operators. For example, to cast a value to an integer, you can use (int) or intval(), to cast to a float, you can use (float) or floatval(), to cast to a string, you can use (string) or strval(), and so on. These typecasting operators allow you to explicitly convert a value from one type to another. For example, (int)$var will cast the value of $var to an integer. It's important to note that typecasting may result in data loss or unexpected behavior if the value cannot be properly converted to the desired type. Therefore, it's recommended to handle typecasting with caution and ensure the appropriate validation and error handling are in place.
