Data type, Number type Data type There are three types of data in PHP: Scalar data type, composite data type, special data type In PHP, a weak data type language, a variable in PHP can store any type of data. The variable type is determined by the

Original question:There is a structure like this:struct A{ long a1; short a2; int a3; int *a4;}; What is the size calculated with sizeof (struct A) under the 64-bit compiler? Answer:--------------------------------------------------------------------

A variable is a container for temporary storage of values. These values can be numbers, text, or a much more complex permutation combination.Variables are at the heart of any programming language, and understanding them is the key to using PHP. The
