Watch out while using continue and a do loop.
When there is a continue inside a do while structure, it does not automatically return to the top of
the loop. It tests the exit condition before it does this.
$x = 0;
do
{
$x++;
if ($x == 100)
continue;
echo $x;
}
while ($x < 100)
In this case, the loop would not do a 101th iteration. The exit condition is still tested even with
a continue. This may seem obvious and it is a rare occurence, but in larger coding structures, with
many variables, it may be hard to notice.
