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。

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.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

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.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
