Heredoc Question

[den160593]

Hi,

I'm currently working out of the book, and the example in the book is as follows:

while ($row = mysql_fetch_array($result)) {
	$movie_name = $row(['movie_name'];
	$movie_director = $row['movie_director'];
	$movie_leadactor = $row['movie_leadactor'];

$movie_details .=<<<EOD
<tr>
	<td>$movie_name</td>
	<td>$movie_director</td>
	<td>$movie_leadactor</td>
</tr>
EOD;
}

I was just wondering. Why is it .<<<EOD. Like why the dot (.)

I mean according to the PHP Manual it should be:

$xpz = <<<EOD

But it isn't. Why the dot? I'm just trying to understand so that in the future I don't make mistakes with this.

NOTE = It isn't a typo from the book. It happens in two locations, further down the code aswell

Thanks

".=" appends the string on the right to the string on the left, whereas "=" just assigns (overwrites) it.

PS: Your closing "EOD;" must not have any spaces/tabs before (or after) it.
