adding text to variables

[jbbaxx]

I'm using PHP, MySql, DreamweaverMX, and PHAkt 2. I want to add a comma ( , ) to the end of a variable, but only if it exists in the database. (Meaning I don't want a comma with no variable.) I seem to remember a format that didn't use an if/else statement that looked something like:
<?php echo xxx( $variable, \,) ?>
The elements were similiar to returning a date with formatting:
<?php echo DoDateTime( $current, 'l, F Js Y') ?>
Thanks.

adding text to variables??

simple do this

<?php
$variable = "i am here";
// now adding not just a comma, but a text 🙂
$variable .= " , do you see my tail?"
echo $variable;

?>
