php实现转换html格式为文本格式的方法_PHP
本文实例讲述了php实现转换html格式为文本格式的方法。分享给大家供大家参考,具体如下:
有时候需要转换html格式的字符串为文本,但又需要保持一定的格式,比如要求段落变成的分段格式就可以用下面这个函数
function html2text($str){ $str = preg_replace("/<style .*?<\\/style>/is", "", $str); $str = preg_replace("/<script .*?<\\/script>/is", "", $str); $str = preg_replace("/<br \\s*\\/>/i", ">>>>", $str); $str = preg_replace("/<\\/?p>/i", ">>>>", $str); $str = preg_replace("/<\\/?td>/i", "", $str); $str = preg_replace("/<\\/?div>/i", ">>>>", $str); $str = preg_replace("/<\\/?blockquote>/i", "", $str); $str = preg_replace("/<\\/?li>/i", ">>>>", $str); $str = preg_replace("/ /i", " ", $str); $str = preg_replace("/ /i", " ", $str); $str = preg_replace("/&/i", "&", $str); $str = preg_replace("/&/i", "&", $str); $str = preg_replace("/</i", "<", $str); $str = preg_replace("/</i", "<", $str); $str = preg_replace("/“/i", '"', $str); $str = preg_replace("/&ldquo/i", '"', $str); $str = preg_replace("/‘/i", "'", $str); $str = preg_replace("/&lsquo/i", "'", $str); $str = preg_replace("/'/i", "'", $str); $str = preg_replace("/&rsquo/i", "'", $str); $str = preg_replace("/>/i", ">", $str); $str = preg_replace("/>/i", ">", $str); $str = preg_replace("/”/i", '"', $str); $str = preg_replace("/&rdquo/i", '"', $str); $str = strip_tags($str); $str = html_entity_decode($str, ENT_QUOTES, "utf-8"); $str = preg_replace("/&#.*?;/i", "", $str); return $str; }

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.
