php type conversion
|
Using type conversion, you can convert the value of a variable to another type. This conversion is the same as the type conversion in C language. Just insert the temporary data type you want to convert in parentheses before the variable you want to type convert.
The second line of code means "take out the variable value stored in $totalqty, interpret it as a floating point type, and save it in $totalamount". The $totalamount variable will become a floating point type. The converted variable does not change its type, so $totalqty is still an integer type. |

PHP is a widely used server-side scripting language with powerful functions and flexibility, but many beginners may encounter some confusion when dealing with data type conversion. This article will discuss implicit type conversion in PHP and how to understand and apply this feature. In PHP, implicit type conversion refers to the process of automatically converting one data type to another data type without explicitly specifying the type conversion operation. This conversion usually occurs between variables and operators, and PHP will automatically perform it based on the context.
