[Resolved] Combing two variables into 1...need a , between them

[sgtpepper]

Hello,

I am combining two variables into one variable like this.

$allids = $theids . $comma_separated2 ;

What I am getting is

theidscomma_separated2

What I need is

theids,comma_separated2

How can I add a comma between the two variables?

Thanks so much

2 ways

$foo = "$var1,$var2";

// or

$foo = $var1 . ',' . $var2;
