从 php 字符串中删除所有标点符号以获得友好的 seo url
所以，我已经看到了大量的解决方案"在这个网站上，但似乎没有一个完全适合我.我想从帖子名称中去除所有标点符号，以便系统可以为每个帖子动态创建网址.我找到了 David Walsh 的一篇文章，其中提供了有关如何实现这一目标的分步教程.然而，并不是所有的东西都会被剥离.这是文章的链接(以防万一):http://davidwalsh.name/php-seo一>.
So, I've seen a ton of "solutions" on this site, but none of them seem to work fully for me. I would like to strip all punctuation from a post name so that the system can dynamically create urls for each post. I found an article by David Walsh that provides a step by step tutorial on how this can be achieved. However, not everything gets stripped. Here is a link to the article (just in case): http://davidwalsh.name/php-seo.
这是我修改后删除所有标点符号的代码:
Here's the code I've altered to remove all punctuation:
$return = trim(preg_replace('/[^a-z0-9]+/i'," ", strtolower($post_name)));
这是一个示例帖子名称:Testing's, this &更多！
Here's an example post name: Testing's, this & more!
回显 url 时的结果:testing-039-s-this-amp-more.php
Results when I echo the url: testing-039-s-this-amp-more.php
我不知道为什么要保留符号和单引号的 html 代码.有什么想法吗?！?
I'm not sure why it's keeping the html code for the ampersand and the single quote. Any ideas?!?
看起来数据是通过 htmlspecialchars() 或 htmlentities() 某处运行的.首先使用 htmlspecialchars_decode() 或 html_entity_decode() 撤销:
Looks like the data is run through htmlspecialchars() or htmlentities() somewhere. Undo that with htmlspecialchars_decode() or html_entity_decode() first:
$return = trim(preg_replace('/[^a-z0-9]+/i'," ", strtolower(htmlspecialchars_decode($post_name))));
