appending (s)printf output to string

[shadkeene]

I'm parsing some data and organizing it, and now I need to capture it inside a variable.

I've used printf in a manner like this to organize the data:
printf("%-30s %18s %18s\n", "$a", "$b", "$c\n");

Now I have a variable that's storing a string, and I want to append the organized data to the variable.

I tried something like $result.printf("%-30s %18s %18s\n", "$a", "$b", "$c\n");
and it doesn't work. I tried sprintf too.

Any ideas?

Thanks, S

I had to place the sprint statement in a variable first, like this:

$result = printf("%-30s %18s %18s\n", "$a", "$b", "$c\n");

And then concatenate the two variables like this:

$result .= $final_result;

That solved it.

sprintf is what you're needing.

$result = 'some string value';

$result .= sprintf("%-30s %18s %18s\n", $a, $b, $c);
