how to change all web address in textarea to hyperlink when i post to php?
As in a textbox? On the page where its displayed just
echo "<a href=\"./$link\">$link</a>";
Not sure exactly what your question is here ... did that answer it? Or are you looking to parse the textarea and find all links within, then convert to hyperlinks? Maybe using some kind of regexp function?
for example: <textarea name=msg cols=40 rows=5></textarea> $msg = "this is url http://www.phpbuilder.com";
i get $msg from textarea, so how can i change
http://www.phpbuilder.com to <a href="http://www.phpbuilder.com">http://www.phpbuilder.com</a>
