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", 'UTF-8') . ""; # 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.
