PHP中文處理 中文字符串截取(mb_substr)和獲取中文字符串字數(shù)
Jun 13, 2016 pm 12:04 PM
一、中文截取:mb_substr()
mb_substr( $str, $start, $length, $encoding )
$str,需要截斷的字符串
$start,截斷開始處,起始處為0
$length,要截取的字數(shù)
$encoding,網(wǎng)頁編碼,如utf-8,GB2312,GBK
實例:
復制代碼 代碼如下:
$str='腳本之家:http://www.jb51.net';
echo mb_substr($str,0,4,'utf-8');//截取頭5個字,假定此代碼所在php文件的編碼為utf-8
?>
結(jié)果顯示:腳本之家
二、獲取中文長度:mb_strlen()
mb_strlen( $str, $encoding )
$str,要計算長度的字符串
$encoding,網(wǎng)頁編碼,如utf-8,GB2312,GBK
實例:
復制代碼 代碼如下:
$str='腳本之家:http://www.jb51.net';
echo mb_strlen($str,'utf-8');//假定此代碼所在php文件的編碼為utf-8
?>
結(jié)果顯示:24

You can embed PHP code into HTML files, but make sure that the file has an extension of .php so that the server can parse it correctly. Use standard tags to wrap PHP code, insert dynamic content anywhere in HTML. In addition, you can switch PHP and HTML multiple times in the same file to realize dynamic functions such as conditional rendering. Be sure to pay attention to the server configuration and syntax correctness to avoid problems caused by short labels, quotation mark errors or omitted end labels.

The key to writing clean and easy-to-maintain PHP code lies in clear naming, following standards, reasonable structure, making good use of comments and testability. 1. Use clear variables, functions and class names, such as $userData and calculateTotalPrice(); 2. Follow the PSR-12 standard unified code style; 3. Split the code structure according to responsibilities, and organize it using MVC or Laravel-style catalogs; 4. Avoid noodles-style code and split the logic into small functions with a single responsibility; 5. Add comments at key points and write interface documents to clarify parameters, return values ??and exceptions; 6. Improve testability, adopt dependency injection, reduce global state and static methods. These practices improve code quality, collaboration efficiency and post-maintenance ease.
