This trick is not unique to PHP but it can be helpful in cases like this.
print $q{$i};
The contents of the curly braces are evaluated. Here is some sample code:
<?php
$q1=52; $q2=22; $q3=83; $q4=2; $q5=37;
foreach (range(1,5) as $i)
{
print "$q{$i}\n";
}
?>
When you have data like this, it is often better to store it in an array.
