Note that sizeof($x), where $x is a variable that is set but is not an array sizeof, returns 1.
Hence you have to be careful e.g. when you are dealing with arrays of multiple dimensions.
for ($i = 0; $i < sizeof($myarray[$j]); $i++) will not work as expected if $myarray[$j]
hasn't been assigned a value (i.e. an array value).
