Not needed.

while (x) y;

is equivalent to:

while (x)
{
y;
}

You only need to use curly brackets after while() if you want to iterate
over more than one line, like this:

while (x)
{
y;
z;
}

The same is true of if(), elseif(), else, for(), foreach() and probably
others that I'm forgetting.

For example:

<?php
$countTo99 = rand(0,1);
if ($countTo99)
for ($i=0;$i<10;$i++)
for ($j=0;$j<10;$j++)
print "{$i}{$j}\n";
else
print "I decided not to count.\n";
?>
