Here is a design though: For example is I put a link such as http://example.com in textarea . How do I get PHP to detect it’s a http:// link and then print it as print "<a href='htttp://example.com'>http://example.com</a>"; I remember doing something like this before however, it was not fool proof it kept breaking for complex links. Another good idea would be if you have a link such as http://example.com/test.php?val1=bla&val2blablabla%20bla%20bla.bl fix it so it does print "<a href='http://example.com/test.php?val1=bla&val2=bla%20bla%20bla.bla'>"; print "http://example.com/test.php"; print "</a>"; This one is just an after thought.. stackoverflow could also probably use this as well :D Any Ideas Source: Tips4all
