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; }

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
