If your array is shorter than the number of arguments in list(), you will get an "undefined
index" notice.
You can solve it by making sure the array is long enough:
<?php
$array = Array( "one", "two" );
# This will give a Notice: undefined index [2]:
list( $one, $two, $three ) = $array;
# This won't:
list( $one, $two, $three ) = $array + Array( null, null, null );
# If you know count($array) will be at least 1, you could skip the first index:
list( $one, $two, $three ) = $array + Array( 1 => null, null );
# You could of course also use other default values:
list( $one, $two, $three ) = $array + Array( "one", "two", "three"
);
?>
