PHP is by no means cleaver enough to read your mind as to what you want it to
do.
If you want to pass pointers instead of strings then do as this
function one(&$buffer)
{
#processing, return true/false based on success, put result in buffer
}
function two(&$buffer)
{
#processing,...
}
Then do like this:
$variable='input value';
if(one($variable))
if(two($variable))
echo "Result: $variable";
