Php Chinese string truncation method to prevent garbled parsing

When a website calls a news title or abstract, we often intercept a part of the display to make the layout look beautiful, but sometimes garbled characters occur when intercepting Chinese characters, now let's talk about how to solve the problem of intercepting Chinese garbled text.

Using the PHP function substr to intercept Chinese characters may cause garbled characters, mainly because substr may generate a Chinese character "sawing" into two halves.

Solution:

1. use mb_substr of the mbstring Extension Library to intercept the database without garbled characters.

2. write the truncation function by yourself, but it is not as efficient as using the mbstring Extension Library.

3. if you only want to output the intercepted string, use the following method: substr ($ str, 0, 30). chr (0 ).

The substr () function can split text. However, if the text to be split contains Chinese characters, you can use the mb_substr ()/mb_strcut function, mb_substr () the usage of/mb_strcut is similar to that of substr (), but an additional parameter must be added at the end of mb_substr ()/mb_strcut to set the character string encoding. However, php_mbstring.dll is not enabled on the server, in php. ini opens php_mbstring.dll.

For example:

Output: in this way, my words

Output:

Mb_substr is used to split characters by words, while mb_strcut is used to split characters by bytes, but it does not produce half a character.

PHP implementation of Chinese string interception without garbled characters

 (127) {$ content. = substr ($ str, $ I, 2); $ I ++; // www.jbxue.com} else {$ content. = substr ($ str, $ I, 1);} if (++ $ count = $ mylen) {break ;}} echo $ content ;} $ str = "34 People's Republic of China 56"; substr_CN ($ str, 3); // output in 34?>
