quick ereg() question

[Joe826]

Hi,

I'm attempting to get ereg() to extract URLs, and I don't see why this code won't do it. Any help would be appreciated.

<?php
$testvar="aaaahttp://www.test.combbbb";

ereg("^{(.)(([url]http://[/url]){1}(.)(/.)?(.)(/.com|/.net|/.org){1})+(.)$",} $testvar, $matches);

print $matches[2]."\n";
?>

Here's what I was thinking on the expression:

^(.) // the string can start with any/no character
(([url]http://[/url]){1} // look for instances where [url]http://[/url] is shown once
(.) // allows for www or any other subdomain.
(/.) // look for the . once or zero times, depending on the url
(.)// the domain name
(/.com|/.net|/.org){1})+ //locate the ending com,net, or org once. also, there must be atleast one url.
(.)$ // allow for any other characters, then end the string.

Hi, in some cases you are right, but:

The escape character is a backslash, not a forward slash.
/. means a forward slash followed by any character
and what you want is . which is a dot.

You never need to specify "exactly 1 occurrence" with {1}, this is the default.

You should not need ^(.) and (.)$ either since every string has a beginning what may be followed by some characters or not, and I think you are not interested in this part, am I right?

The article section contains an article that explains the general syntax elements quite well as far as I remember.

Hope this helps,
