[SOLVED] Combining two variables together to make a new one?

[hatrickpatrick]

Supposing I have one variable, $file=filename, and a second variable, which is $number='99';

How can I make a third variable, $fileno which will equal filename99? I'm guessing it's not as simple as $fileno=$file$number...

This is called concatenation:

 

$var = $var1 . $var2;

[BlueSkyIS]

or..

 

 

$fileno="$file$number";

 

(just add double-quotes)

Thank you VERY much. Just one more thing - using the first method, if I wanted to separate the two variables with an underscord, so it'd be filename_99, how would I add that in?

Based on the example below, how do you think it would be done? The concept has already been demonstrated. Are you familiar with strings?

$var = $var1 . $var2;
