A simple method to count the number of Chinese characters in PHP

The example in this article describes how to simply count the number of Chinese characters in PHP. I share it with you for your reference. The details are as follows:

The previous company was engaged in foreign trade and all the products used were in English, so when counting the length, I used the strlen function, and there was no error. But now when counting Chinese, this function Something went wrong, now do a record test

<?php
echo strlen("你好ABC") . "";
# 输出 9
echo mb_strlen("你好ABC", &#39;UTF-8&#39;) . "";
# 输出 5
echo mb_strwidth("你好ABC") . "";
#输出 7
?>

From the above test, we can see:

strlen counts Chinese characters as 3 bytes

mb_strlen regardless of Chinese or English, it counts as 1 byte

mb_strwidth counts Chinese as 2 bytes

So when calculating the length, use the mb_strlen function

I hope this article will be helpful to everyone in PHP programming.
