正则表达式匹配
想用正则表达式匹配这种格式
<br /> <?php<br /> <br /> <br /> <br /> $con= file_get_contents("http://17173.com");<br /> <br /> $preg = '#<LI><A href="(.*)" target="_blank">(.*)</A>#';<br /> <br /> preg_match_all($preg, $con, $arr); <br /> <br /> //print_r($arr[1]);<br /> <br /> foreach($arr[1] as $id=>$v){<br /> <br /> echo "<a href=$v>".$v."</a> ".$arr[2][$id]."<br>";<br /> <br /> }<br /> <br /> ?><br /> <br />
匹配结果是没东西,但是这个页面中是有这种格式链接的,求解
------解决方案--------------------
首先 target="_blank"和上面给出的是不符合的,到底是哪个?
然后再echo $con;看看
确定有期望的内容
再注意大小写和换行的问题――你的正则固定了大小写,圆点是不包含换行的
------解决方案--------------------
preg_match_all('/
var_dump($matches[1]);
你的问题是:人家网站的内容是target=_blank这样的,而你的target="_blank"却是这个,多了引号,匹配不到。

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.
