Try this:
// Populate an array of random length
for ($i = 0; $i < rand(300, 600); $i++) {
$l_aTest[] = '...';
}
$l_iLength = count($l_aTest);
$l_iLow = floor($l_iLength / 3);
$l_iHigh = ceil($l_iLength / 3);
$l_iMod = $l_iLength % 3;
$l_iFirst = $l_iHigh;
$l_iSecond = ($l_iMod < 2 ? $l_iHigh - $l_iMod : $l_iHigh);
$l_iThird = $l_iLow;
echo "<p><strong>Your columns are: $l_iFirst, $l_iSecond,
$l_iThird</strong></p>";
