Parsing a string

How do I take text between two symbols, and do something with it, for example;

Taking these forums as an example, you can do [ url]http://www.alistairbaillie.co.uk[ /url]. (Without the sapces) and it automatically makes it a URL.

I know I could change the [ url] to <a href=" and the [ /url] to ">Click me</a>

but this doesn't give the same effect.

If anyone knows how I can achieve this, i would be gratefull.

use str_replace()

http://www.php.net/manual/en/function.str-replace.php

You would however need a more advanced replace function such as ereg_replace() if you wanted [ url=www.blah.com]Text[ /url]

Check out this thread. Same concept.

how about this code:

Code:

---

<?php
$searcharray = array("/(\[)(url)(=)(['\"]?)([^\"']*)(\\4])(.*)(\[\/url\])/esiU",
                              "/(\[)(url)(])([^\"]*)(\[\/url\])/esiU");
$replacearray = array("showurl('\\5', '\\7')",
                                          "showurl('\\4', '\\4')");
$str = "hello.net<br>
                  http://www.vbworld.net";
echo $str."<br><br>";
$str=preg_replace($searcharray, $replacearray, $str);
echo $str;

function showurl($url, $hyperlink) {
return "<a href=\"$url\">$hyperlink</a>";
}
?>

---

That will handle [url] & [url=] without trouble.

Hope that's what you want :D

that didn't post correctly..

quote it to get the actual code..
