Result:
Parse error: syntax error, unexpected T_SL on line 3
The parser is complaining because you have whitespace after the angled brackets declaring a heredoc. You need to make sure you're actually following the heredoc syntax, which you can find on the PHP Manual site (specifically: http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc).

this is my text
