How do I append data to a field?

[bayridge]

I have a field that I want to append to during my script execution. For instance, I start with the code:

$field = "partone";

This works fine, $field one is equal to "partone". Then some more code.

And then I want to add to $field:

$field = $field + "parttwo";

This doesn't work. $field is "0" after this executes. I want $field to contain "partone parttwo" at this time. I am a newbie to php.

Thanks for any help.

$field = "partone";
$field .= "parttwo";

The same way string concatenation is done in Perl, NOT JavaScript...
