What is type juggling? PHP changes the value to a specific data type based upon the context of how it is being used. Huh? For example, you are trying to compare a string number to a number. PHP converts the string to an integer for the comparison. It juggles the data type from string to integer.
It is important for you to know how type juggling works to ensure you get the results you require. It may not behave the way you think, which can lead to unexpected behavior in your code.
