substr - PHP - 中英文混排字符串截取函数
RT 求一个中英文混排字符串截取的函数,substr(), mb_substr(), iconv_substr()貌似都不太给力的说,网上放出来的自定义函数也试过一些,没有好用的.= =!
其实我的主要目的是想截出来的几行字的长度是一模一样的,所以求教一下~
补充:
下面是我测试用的代码,貌似第一个和第二个答案得出的都有乱码的问题的说~
PS:回答问题的可以先用我的那段测试小文本测试一下,通过了再提交答案的说~
<?php $one = '20'; $text = 'Nokia阿根廷部门开发了Angry Birds和Fruit Ninja书签工具,通过此书签玩家就可以在任何网站裡开启Angry Birds和Fruit Ninja畅玩,而且你发射的小鸟会破坏网页架构,你切水果的手势也会顺便把网站大卸八块。'; $count= mb_strlen($text); $row = ($count - $count%$one)/$one; if($count%$one != 0) { $row = $row+1; } for($i=0;$i< $row;$i++) { echo mb_strimwidth($text, $i*$one, $one); echo '<br />'; }

我想你需要的就是mb_strimwidth
这个函数,去看看它的定义吧 http://cn2.php.net/manual/en/function...
我用了一个比较恶心的方案。假设你的字符串是utf-8编码,那么需要转成gbk
$gbk_str = iconv('UTF-8', 'GBK', $raw);
然后substr去截这个$gbk_str,gbk编码的汉字是两个字节,英文是一个,所以刚好。

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

IIS and PHP are compatible and are implemented through FastCGI. 1.IIS forwards the .php file request to the FastCGI module through the configuration file. 2. The FastCGI module starts the PHP process to process requests to improve performance and stability. 3. In actual applications, you need to pay attention to configuration details, error debugging and performance optimization.

AI can help optimize the use of Composer. Specific methods include: 1. Dependency management optimization: AI analyzes dependencies, recommends the best version combination, and reduces conflicts. 2. Automated code generation: AI generates composer.json files that conform to best practices. 3. Improve code quality: AI detects potential problems, provides optimization suggestions, and improves code quality. These methods are implemented through machine learning and natural language processing technologies to help developers improve efficiency and code quality.

Laravel optimizes the web development process including: 1. Use the routing system to manage the URL structure; 2. Use the Blade template engine to simplify view development; 3. Handle time-consuming tasks through queues; 4. Use EloquentORM to simplify database operations; 5. Follow best practices to improve code quality and maintainability.

Configuring and running PHP on IIS requires the following steps: 1) Download and install PHP, 2) Configuring IIS and adding FastCGI module, 3) Create and set up an application pool, 4) Create a website and bind to an application pool. Through these steps, you can easily deploy PHP applications on your Windows server and improve application stability and efficiency by configuring scaling and optimizing performance.
