variable and if clause

[bgimaf]

Hi everyone,
I have the following problem and need help.
I get a variable from a database containing a link.
Now i want to differ between an external and an internal link as to the target is either _blank or opens the page in the same content.

How can I read out the variable including it in an if-clause ?

Thought :

if variable link
contains http
than do <a href"$link" target="_blank">
else
do <a href"$link">

Any help in this matter would be great

have you looked in the manual for regular expressions?

<?php
&nbsp;&nbsp;&nbsp;&nbsp;if (eregi("http://"), $link) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// generate link with "blank"
&nbsp;&nbsp;&nbsp;&nbsp;} else {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// generate link without "blank"
&nbsp;&nbsp;&nbsp;&nbsp;}
?>
