Question

This is what i have:

    ob_start();
    for ($i=0; $i<count($_POST['checkbox_checker']);$i++) {
    echo "<br />".$_POST['checkbox_checker'][$i];
    $selection = ob_end_flush();
    }

I am then using $selection to store in a database since i am unable to find a way to use sessions to store checkboxes. The problem is when i use $SELECTION = ob_end_flush(); the values still echo. How can i make it so the values that are supposed to be echoed get stored inside of $selection and don’t show to the user?

The actual solution, btw, would be to not use the echo. You don’t need that workaround if you just append to a string variable:

for ($i=0; $i<count($_POST['checkbox_checker']);$i++) {
   $str .=  "<br />".$_POST['checkbox_checker'][$i];
}

(And you could also read up on foreach. Or even implode() in this case.)
