How do you load a php variable value into a form field as a default value?

[Conjurer]

I saw some code somewhere and can't remember now how you do it. But they had a text box in a form and they wanted to show the user the current value that they returned from a database and then give them an option to change it.

 

They set a variable like $foo = "bar"

and then somehow used php for the default value of the form box to get it to show the value "bar"

 

How do you do that?

<?php

$foo = //mysql query that returns one text based result

print "<form>";
print "<input type='text' name='title' value='$foo'/>";
print "</form>";
?>

oh wow!

That isn't what I was thinking of, but it will work for me.
