Change a relative URL to absolute URL
hyperlink, php, regex, url
Solution
found a good way :
$html = preg_replace("#(<\s*a\s+[^>]*href\s*=\s*[\"'])(?!http)([^\"'>]+)([\"'>]+)#", '$1http://mydomain.com/$2$3', $html);
you can use `(?!http|mailto)` if you have also mailto links in your $html
Problem
for example i've got a string like this: ``` $html = ' <a href="test.html">test</a> <a href="http://mydomain.com/test.html">test</a> <a href="http://otherdomain.com/test.html">test</a> <a href="someothertest/otherdir/hi.html">hi</a> '; ``` and i want to append the absolute url to all hrefs where no abolute domain is given. ``` $html = ' <a href="http://mydomain.com/test.html">test</a> <a href="http://mydomain.com/test.html">test</a> <a href="http://otherdomain.com/test.html">test</a> <a href="http://mydomain.com/someothertest/otherdir/hi.html">hi</a> '; ``` whats the best way to do that? i guess something with RegEx, but my RegEx skills are ** ;) thanks in advance!
