echo <<<tag ... tag;

[Michael G]

Some of the online docs say that you can use

echo <<<END

all sorts of text and statements...

END;


but if the following produces a parse error at line 14 which is the closing
php tag.

<?php
echo <<<TT
<tr>
<td>
<p>1. some text...</p>
</td>
<td>
<p>
<input type="radio" name="gs.$i" value="1">
</p>
</td>
</tr>
TT;
?>

Any suggestions, like don't use this tag?

Thanks, Mike

Just a guess, but it looks like you're trying to reference a PHP variable inside
the echo?
name="gs.$i"

I'd try something like this:

<?php
echo <<<TT1
<tr>
<td>
<p>1. some text...</p>
</td>
<td>
<p>
TT1;

echo "<input type=\"radio\" name=\"gs." . $i . "\" value=\"1\">";

echo <<<TT2
</p>
</td>
</tr>
TT2;
?>

If $i==7, the result of this will look like:

<input type="radio" name="gs.7" value="1">

Probably not what you intended.

Make sure this is on column 1 of the line, and there isn't anything
after it (including whitespace).

HEREDOC syntax is quite useful in many cases, and I tend to use in cases
like this where I have a large HTML block to output with a couple
variables in it.

Hi![color=blue]

Your error occurs if the closing
TT;
does not start at the very beginning of the line.

$x= <<<TT
some text
TT;

fails;

$x= <<<TT
some text
TT;

works!

to prevent this error because of the autoindent of my editor I prefer a
coding style like this:

if(something) {
$var=
<<<EOT
sometext
sometext
EOT;
}

Take a look at some of the templating systems out there - I use Smarty -
