This article mainly introduces the PHP data type conversion and detection, has a certain reference value, now share to everyone, the need for friends can refer to 1. Conversion of data types Although PHP is a weakly typed language, it is also possible to convert data in the

High byte priority and low byte priority. Data on the internet is transmitted over the network in high byte precedence. Therefore, for machines that store data in low byte precedence mode, data transmission over the Internet requires conversion. The first structure type is: struct sockaddr. This type is used to save so
