preg_replace question

M2_

Ok... I'm fairly new to PHP, and very new to this forum (looks promising). But, I have found my way around PHP thus far without too many hookups. However, I do have a problem using the preg_replace function. I am trying to remove the [url]http://[/url] tag from returns from a MySQL database.... I have some sucess, until certain characters appear.... ie -, ?, etc. Is there a method of maintaining urls with extra characters?

Here is the code....

<?

$link1 = "http://www.phpbuilder.com/";
$link2 = "http://www.cnn.com/SPECIALS/2003/iraq/";

$link1 = preg_replace("/\b((http(s?):\/\/)|(www\.))([\w\.]+)([\/\w+\.]+)\b/i", "<u><a href=\"http$3://$4$5$6\" target=\"_blank\">$4$5$6</a></u>", $link1);
$link2 = preg_replace("/\b((http(s?):\/\/)|(www\.))([\w\.]+)([\/\w+\.]+)\b/i", "<u><a href=\"http$3://$4$5$6\" target=\"_blank\">$4$5$6</a></u>", $link2);

echo "$link1\n\r<br>";
echo "$link2\n\r<br>";

?>

Example

Thanks 😉

if all you want to do is drop the [url]http://,[/url] use str_replace()

$link = "http://www.yahoo.com";

$link = str_replace("http://", "", $link);

Thanks.

Would that also work if the $link was a full text string returned from a MySQL database? i.e. -

$link = "If you visit [url]http://www.yahoo.com[/url] you can find many useful tools";

yup!

... ok, that gets my part way there. But, what about converting the string to make the http: reference to a link opening in a _blank window? That's why I originally used preg_replace, because I could not get it to work with str_replace.

Thanks.

... using this works.

<?
$url = "http://www.php.net/manual/en/function.preg-replace.php"

$url = "preg_replace("/((http(s?):\/\/)|(www\.))([\S\.]+)\b/i", "<a href=\"http$3://$4$5\" target=\"_blank\">$4$5</a>", $url);

echo "$url";
