Class parameter vanishes the moment it goes into the class!

[Phil Powell]

I have a variable with a value that I've verified countless times by
using both echo and print_r; both indicate the variable exists and has
a value. The moment I instantiate a class where this variable is
passed as a parameter, the value literally VANISHES! I cannot figure
out a way within the "constructo r" of the class to determine if the
passed parameter has a value since both echo and print_r do not even
render within there.

How can I determine my parameter has a value? I tried writing a
getParameter style function only to again show that there is no value.

I could produce the class code but it's about 200 lines long, the
class itself calls about 30 parameters.

Thanx
Phil

Not enough information.

Post code, a code snippet, or a URL to code. If it's long, a URL is
preferred.

print_r will show the variable when it is initiated in the constructor.
Example:

<?
class Test {
var $testparam;

function Test($testparam ) {
$this->testparam = $testparam;
}
}

$test = new Test("Hello class");

print_r($test);

// Result:
// test Object ( [testparam] => Hello class )
?>

When you want to retrieve the value of $testparam from within the class, you
could do either:
echo $test->testparam;

Or (and this way is much better)
through an accessor method in the class which returns $this->testparam
