I am relatively new to PHP. But something I can't seem to make work is when
I call one of the functions I have made and a variable is set inside that
function....
eg. function blah ($bl,$ah) {
$bl++;
$ah++;
$blah=$bl+$ah;
}
I then echo $blah; somewhere else in the script but nothing is echo'd. How
do I make it so that I can use $blah anywhere in the script?
Thank you in advance for any help.
