Description: ------------ A quoted value in a nowdoc, like "$456", gives an error: Variable "456" is not in valid camel caps format According to "http://php.net/manual/en/language.types.string.php", text in nowdocs is not parsed. phpcs should not be flagging an error here. Test script: --------------- $ cat foo.php <?php $foo = <<<'BAR' $123 "$456" BAR; Expected result: ---------------- Nothing. Actual result: -------------- $ php PHP_CodeSniffer/scripts/phpcs -- foo.php -- standard=Zend FILE: /Users/brkendig/foo.php ------------------------------------------------------------------------ -------- FOUND 1 ERROR(S) AFFECTING 1 LINE(S) ------------------------------------------------------------------------ -------- 4 | ERROR | Variable "456" is not in valid camel caps format ------------------------------------------------------------------------ --------

The same error also occurs in heredocs. php won't recognize $456 as a valid variable name, so phpcs shouldn't be catching it either.

Fix committed. PHP tokenizes heredocs and nowdocs using the same tokens, but that confuses some sniffs. PHP_CodeSniffer now detects nowdocs and uses it's own token types. So look for T_START_NOWDOC instead of T_START_HEREDOC if you want to detect nowdocs specifically.
