Description: ------------ I ran php_cs on a source file that had a function in it with an argument. php_cs incorrectly said that the function never used the argument but it did. I was able to reduce the problem down to a single sample file, in the "Test script" section. The spacing is important, as noted in the source There may be other ways to get this to fail, but this one is the smallest I was able to come up with and make it repeatable.lk Test script: --------------- <?php function foo( $parameter ) { $wango = <<<HERE 1 Must be a HEREdoc of at least one line HERE; $x = $parameter; // This line must be immediately after the HERE; with no intervening blank lines. $tango = <<<HERE 1 Must be a HEREdoc 2 3 4 5 6 7 8 9 at least 9 lines long HERE; } Actual result: -------------- FILE: /home/alester/scraps/sniffbugs.php -------------------------------------------------------------------------------- FOUND 0 ERROR(S) AND 1 WARNING(S) AFFECTING 1 LINE(S) -------------------------------------------------------------------------------- 2 | WARNING | The method parameter $parameter is never used --------------------------------------------------------------------------------
