here doc

Anon

 Ok I want to use something that is similar to here but executes the php code in it.  For example

$operatingSys = "linux";

$blurp = <<<EOD
My favorite operating
system is $operatingSys
because its free
EOD;

print $blurp;

What I am trying to do is not that simple but what happens is that using the here structure I will get a "system is $operatingSys" instead of "system is linux".

Any help?
For my two previous posts I never got any help. I hope I get some here.

why dont you use:

$blurp = "system is $operatingSys ..... ";

this is deffinately work. i am not sure about that EOD thing.

I wish it was that easy. Ok here is a very tiny bit of my code:

function returnBar( )
{
$nMenu = 1;
?>

<HEAD>
<TITLE>
    <?php print $this->arNav[ 8 ]; ?>
    </TITLE>

ok see how its in a class? this is only the title, I proceed having a bunch of for loops. Basically it generates a bunch of dynamic dhtml menus with submenus. Now for a weird reason that I cannot conceive my boss wants me to return the whole bar I generate as a string. If is it to become a string I need to say something to the effect of
$html = "\n<HEAD>\n<TITLE>\n" . $this-arNav[ 8 ] .....

and keep going which is very ugly and stupid. If I use here doc (go to php.net quick search string functions and you will find it) I can copy big amounts of text the way it looks BUT it doesn't interpret any of the variables 🙁

Yes I know complexity to its greatest.

There is here doc support on PHP4, try the following:

<?php

class foo {
var $bar;
function foo($val) {
$this->bar = $val;
}
}

$o = new foo("boing!");

print <<<EOF
<pre>

And the ball made $o->bar
and rolled down the slope

</pre>
EOF;
?>

Which when run, will print:

And the ball made boing!
and rolled down the slope

I know what you're trying to do. It's a useful trick that is often used in perl. It's now possible in PHP4. The syntax is slightly different, though.

In PHP:

$operatingSys = "linux";

$blurp = <<<EOD
My favorite operating
system is $operatingSys
because its free
EOD;

print $blurp;

That's all. It works with all double-quotish variable interpolation, including concatenation with another such variable.
EOD can be replaced with whatever you want, as long as it follows variable name guidelines. (lowercase is fine, too).
