【问题描述】:
嘿,我正在尝试做 2 个 preg_replace: 1.将所有网址制作成html链接 2.将所有图片的url转成html的img标签
但是这些正则表达式取消了另一个
<?php
// The Regular Expression filter
$reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";
$reg_exImg = "!http://[a-z0-9\-\.\/]+\.(?:jpe?g|png|gif)!Ui";
// The Text you want to filter for urls
$text = "The text you want to filter goes here. http://google.comhttp://www.ynet.co.il http://dogsm.files.wordpress.com/2011/12/d7a1d7a7d795d791d799-d793d795.jpg";
// Check if there is a url in the text
$text = preg_replace($reg_exImg, '<img src=$0 >', $text);
$text = preg_replace($reg_exUrl, '<a href="$0" rel="nofollow">$0</a>', $text);
echo $text;
?>
我怎样才能让 preg_replace 使链接的 url 不对标签执行此操作?
谢谢。
海姆
