include_once Dynamic <option></option>

[fuzzy1]

Just when I start thinking I'm all clever!

I put together a little script (comOpts.php) which outputs the following source code
(which is what I'm after--sort of) thinking I would then call it into "makeComBox.php" using
"include_once('comOpts.php')", but of course that doesn't work.

//view source gets me
$comOpts1="
<option value='Select Option'>Select Option</option>
<option value='Red'>Red</option>
<option value='Green'>Green</option>
<option value='Blue'>Blue</option>
";
$comOpts2="
<option value='Select Option'>Select Option</option>
<option value='Cyan'>Cyan</option>
<option value='Magenta'>Magenta</option>
<option value='Yellow'>Yellow</option>
";

Please, how might modify "comOpts.php" to pass the $variables (as output above) into the file "makeComBox.php" OR otherwise CALL the variables into makeComBox.php from "comOpts.php"

<?php //comOpts.php
$colorOpt=array(
	array("Select Option",
		"Red",
		"Green",
		"Blue"
		),
	array("Select Option",
		"Cyan",
		"Magenta",
		"Yellow"
		)
);
$row_count = count($colorOpt);
for ($row = 0; $row < $row_count; $row++)
{
$name='$'.'comOpts';
$optCount=$row+1;
$optName=$name.$optCount;
$option = $optName.'="';
$option .= "\r\n";
    foreach($colorOpt[$row] as $key => $value)
    {
    $option .= "\t".'<option value=\''.$value.'\'>' . $value.'</option>'."\r\n";
    }
	$option .= '";'."\r\n	";
echo $option;
}
?>

included files gets parsed. Output (what you write to user using echo) of the included file isn't parsed - it is just echoed to the user. The solution to your problem would be to use variable variable names:

$var_name = $name.$optCount;
$$var_name = 'options here';

Thank You wilku for the effort.
I guess I just don't quite understand your intent. I only recently discovered Variable Variables, and have been reviewing the manual and any tutorials I can find for several hours now while trying variations on the theme, but I can't for the life of me figure how to apply in this instance.
Stumped.

<?php //comOpts.php 
$colorOpt=array( 
    array("Select Option", 
        "Red", 
        "Green", 
        "Blue" 
        ), 
    array("Select Option", 
        "Cyan", 
        "Magenta", 
        "Yellow" 
        ) 
); 
$row_count = count($colorOpt); 
for ($row = 0; $row < $row_count; $row++) 
{ 
$name='comOpts'; 
$optCount=$row+1; 
$optName=$name.$optCount; 

$$optName = ""; 
    foreach($colorOpt[$row] as $key => $value) 
    { 
    $$optName .= "\t".'<option value=\''.$value.'\'>' . $value.'</option>'."\r\n"; 
    } 

after running this script, you'll have $comOpts1 and $comOpts2 available in the global scope (it will not automatically show to the browser - you'll need to echo $comOpts1 to show the first of the variables, where you want them).

Well wilku, I certainly didn't intend that you should rewirte my code for me!
It is SO simple and elegant I just can't hardly stand it.
I only wich I understood it.

My past (recent) experience with Variable variables was with the V-v on the other side of the equation ($var1 =$$var2) so as to pass the Name of $var2 into a script.
What it appears to me here is that with the Vv to the left of the equation ($$var2 = "some values") we return the VALUE of $var2 --- into the script ????

I like it! Don't quit get it, but I really like it.

THANK YOU!!!

To help you understand:

//this
$name = 'var1';
$$name = 'something';
//is the same as
$var1 = 'something';
