Question

让我们像[n]个链接一样拥有这样的php string：

This is a text with a link to [LINK]https://website.com/page/subpage/id This is the text to display[/LINK] and another link to [LINK]https://website2.com/page/subpage/subsubpage/subsubsubpage This is the text to display for link 2[/LINK]. Wow!"

如何将[LINK]和[/ LINK]替换为a href并显示链接的文字？

Lik this：<a href="https://website.com/page/subpage/id" target="_blank">This is the text to display</a>

我已经尝试preg_replace但是无法理解它，因为它是超级怪人！

Answer 1

<?php

$str='This is a text with a link to [LINK]https://website.com This is the text to display[/LINK] and another link to [LINK]https://website2.com This is the text to display for link 2[/LINK]. Wow!';

$pattern='/\[LINK\]([\w:\/\.]+) ([^(\[\/LINK\])]+)\[\/LINK\]/';

echo preg_replace($pattern, '<a href="${1}" target="_blank">${2}</a>', $str) ;

?>

输出

This is a text with a link to <a href="https://website.com" target="_blank">This is the text to display</a> and another link to <a href="https://website2.com" target="_blank">This is the text to display for link 2</a>. Wow!

PHP preg_replace [LINK] mylink [/ LINK]
