Type juggling and type casting can be used to change a value's type. When PHP converts a value from one type of value to another, it is called type juggling. When you explicitly set a type to change the value into another type, it is called type casting. While programming, it's important to know the type of the value and use type casting or juggling to convert it to compatible types.
