A triple === adds type checking to your conditional.

For example,

$var = 1;
$var2 = "1";

if ($var == $var2)  { echo "loose-type checking  -- equal"; }

/* This will never print */
if ($var === $var2) { echo "strict type checking -- equal"; }

See http://www.php.net/manual/en/language.operators.comparison.php

Hope this helps,
