PHP: Suppress output within a function?

Question

What is the simplest way to suppress any output a function might produce? Say I have this:

function testFunc() {
    echo \'Testing\';
    return true;
}
         


        

Answer 1

Yes you are on the right track as to leveraging PHP's output buffering functions, i.e. ob_start and ob_end_clean (look them up on php.net):
