Examples of strlen and mb_strlen usages in PHP _php techniques

This article analyzes the usage of strlen and Mb_strlen in PHP. Share to everyone for your reference, specific as follows:

First look at the following code (file encoding UTF8):

<?php
$utf 8_string = "ABCD I you he she it";
Var_dump (strlen ($utf 8_string));
Var_dump (Mb_strlen ($utf 8_string, ' gb2312 '));
Var_dump (Mb_strlen ($utf 8_string, ' UTF8 '));
Var_dump (Mb_strlen ($utf 8_string));

The 2nd parameter is the same as the original encoding of the string, and it calculates the real word in the human understanding sense. (only 1 times in Chinese text)
