Using a variable outside of the while loop (scope)

Question

Small problem regarding scope in PHP, I can\'t seem to call the variable $report outside of the while loop. I have tried various things, including return. This

Answer 1

You could try to define the variable before the loop, e.g.

$report = "";
while ($row = mysql_fetch_array($result)) {
    $report .= "a"."b".$row["prevDOCid"]+1;
}
echo $report;

I hope this helps you!

Edit Use .= not +=
