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

Here you go:

ob_start();
testFunc();
ob_end_clean();

"ob" stands for "output buffering", take a look at the manual pages here: http://www.php.net/outcontrol
