Reviewing a code, I found something in Heredoc notation:

<?php

$html = <<<XXX
            <script type="text/javascript">
            ...
            </script>
XXX; //must be begin in column 0 or ERR

echo $html;

This code, when executed, produces an error and I do not know why:

Parse error: syntax error, unexpected end of file in D:\PHP\heredoc.php on line 10

Line 10 is the last of the script .

The syntax HEREDOC set for the tag Closing that:

It has to be at the beginning of the line.
Nothing more than the closing tag on that line is allowed.

That is, that comment can not be on the same line as the closing:

$heredoc = <<<XXX
    ...
XXX; // Este comentario genera que no se cierre (ERROR) <----

Fixed:

<?php

$html = <<<XXX
            <script type="text/javascript">
            ...
            </script>
XXX;
//must begin in column 0 or ERR

echo $html;
