fri3ndly Posted March 7, 2008 Share Posted March 7, 2008 Hi everyone I have (what I think is) a quick question... I have a variable called $article which contains a paragraph of text and a link at the bottom. How would I be able to do the following: Extract the <a href="link.html">Link Here</a> out of the variable and place it in to a new one?

puritania Posted March 7, 2008 Share Posted March 7, 2008 You can extract it by using a Regular Expression with preg_match Link to comment https://forums.phpfreaks.com/topic/94870-if-variable-contains-data-do-this/#findComment-485949 Share on other sites More sharing options...
fri3ndly Posted March 7, 2008 Author Share Posted March 7, 2008 Somethiing like this? preg_match("<a href=""></a>", $article) Im not really sure how to use this function properly and haven't found a useful guide yet Link to comment https://forums.phpfreaks.com/topic/94870-if-variable-contains-data-do-this/#findComment-485951 Share on other sites More sharing options...
moon 111 Posted March 7, 2008 Share Posted March 7, 2008 I think preg_match("<a href=\"*\">*</a>", $article); would work. Link to comment https://forums.phpfreaks.com/topic/94870-if-variable-contains-data-do-this/#findComment-485961 Share on other sites More sharing options...
Daniel0 Posted March 7, 2008 Share Posted March 7, 2008 preg_match('/<a href="(.*)">(.*)<\/a>/i', $article, $matches); The match will be stored in $matches. The href will be backreference 1, and the anchor text will be backreference 2. The above regex requires that the anchor tag is always formatted like that.
