Heredoc syntax has some strict rules we have to consider;

1 - There shouldn't be any character after opening identifier

True

"$a = <<<HEREDOC"

False 

"<<<HEREDOC   "   //Remove space after opening identifier;

2 - There shouldn't be any other character after and before closing identifier except delimiter semicolon ; at the end. Also no indentation is allowed.

True

"HEREDOC;"

False 

"HEREDOC  ;"   //Remove space between HEREDOC and ;

False 

" HEREDOC;"   //Remove space before HEREDOC

False 

"HEREDOC; "   //Remove space after ;

Heredoc string. END;

    <?php
        //Heredocs start with <<< and a token ended with semi-colon
        print <<< ENDHEREOK
        We used ENDHEREOK "as" our token
              Looks like it just "print"
              things "as" it is. Let me loooook at what I just typed

        I may add some more! I m gonna end it using ENDHEREOK but any token can be used
        Give it a "try"! Also pay attention to so many double quotes because it is mandatory!
         Also yes "if" you put
        space after token(ENDHEREOK) above, you will get an error, just hit enter key after token!
        Try this on repl.it

        ENDHEREOK;
        ?>
