assign "print $value;" to a variable

[sid]

alright - following problem:

i am working with a ready made pen source script which has a bunch of functions, that PRINT strings, such as

<?
//CODE EXAMPLE 1:
//=============

function foo() {
    $bar = "some string";
    print $bar;
}

foo();

?>


output:
some string

i need to assign the printed out string to a variable though (and not print them). i.e. i need to do something like this:

<?
//CODE EXAMPLE 2:
//=============

function foo() {
    $bar = "some string";
    return $bar;
}

$assignedFoo = foo();
//process value here

print $assignedFoo;

?>


output:
some string

sooo - since i only have functions available like in CODE EXAMPLE 1 (can't rewrite them), but need to treat their printed output like in CODE EXAMPLE 2, i wondered if somebody could help me here.

i remember doing something like this before, but have no clue anymore how or where to start looking at. (buffers???)

thanks in advance!

Well, output buffering would work, provided you have it enabled...

function foo() {
    $bar = "some string";
    print $bar;
}

ob_start();
foo();
$data = ob_get_contents(); 
// do what you want with $data
ob_clean();

should be enabled. thanks a lot dude!
