I'm interested in checking a string for a @ and, if it has one, do something like

if(strstr($msg,'@'))
{   
   <a href="<? echo"$msg"; ?>">
}

I'm not sure how to implement this though. Can it be entered into the html or does it need to go with the php code at the top. And if it goes at the top, how do I enter it in the html?

TIA for the assistance.

Note from PHP.net:

Note: If you only want to determine if a particular needle occurs within haystack, use the faster and less memory intensive function strpos() instead

If you want echo something in the middle of the HTML just put <?php
?> in where you want the echo to be - PHP can be put anywhere, it's only by convention at the top.

This would leave you with something like:

PHP Code:

<?php
if(strpos($msg,'@') !== false)
{
echo $msg;
}
?>

Just put that wherever you want $msg to be echoed.

Hope that helps!

That's good to know, thanks again for the help. My problem now is if it finds an '@' how do I make it insert <a href="mailto:......"> instead of just printing it?

You want

PHP Code:

if(strpos($msg,'@') !== false)
{
echo "<a href=\"mailto:".$msg."\">Something</a>";
} 


You rock.
