Dear Thorsten Schaak, you made a mistake.
Your example is buggy, not PHP. Check the proper syntax, check PHP errors/warnings/notices
PHP deals okay with empty arrays, try yourself:
<?php
$a = array( 'a', 'b', 'c', 'd', 'e' );
$b = array( 'b', 'c' );
$c = array( ) ;
print_r( array_diff( $a, $b ) );
print_r( array_diff( $a, $c ) );
print_r( array_diff( $c, $b ) );
print_r( array_diff( $c, $c ) );
?>
