Combining Strings.

Hi,
I'm trying to combine float varibable into a string but when I do this;

$string = $number1 + ',' + $number2;
//ie if $number1 = 1.1 and $number2 = 2.2 then $string = '1.1,2.2'

etc, it tries to add the numberical values.

I've tried using settype($string,'string') and casting (string), without joy.

In past languages ive used, there would be a str$()/val() type functions. Am I missing the obvious here ?

Thank for all replies in advance

try this instead:

$string = $number1 . "," . $number2;

Should work.

Cheers, works a treat.

So whats the . mean ?

that is the concactenation identifier like if you want to combine variables with regular text you would do something like "var= " . $var

Thanks 🙂
