Can you do it programmitically (with pseudo-code)? After all, we need
to
keep this on-topic :)
</sip>


not pseudo code and it could definatley be cleaned up or done better
but her is my quick try at it

echo "We are walking to up to a fork in the road.<br />";
$randval = rand(1, 500);
$randval2 = rand(1, 500);
$randval3 = rand(1, 500);


if ( $randval&1 )
{
$man1 = "truth";
$man2 = "lie";

}
else
{
$man1 = "lie";
$man2 = "truth";
}


if ( $randval3&1 )
{
$road1 = "Utpoia";
$road2 = "Black Forest";

}
else
{
$road1 = "Black Forest";
$road2 = "Utpoia";
}

if ( $randval2&1 ) $manToAsk = "Man 1";
else $manToAsk = "Man 2";



if ($manToAsk == "Man 1") {
echo "We are asking Man 1<br />Man 1, where would Man 2 point if
I asked him to point to the road to Utopia?<br />";
if (man1() == "Road 1") {
echo "Man 1 pointed to Road 1<br />";
$roadToTake = "Road 2";
}
else {
echo "Man 1 pointed to Road 2<br />";
$roadToTake = "Road 1";

goes to $road2<br />Man 1 = $man1<br />Man 2 = $man2";
//echo "We took $roadToTake<br />We asked $manToAsk<br />Man 1 =
$man1<br />Man 2 = $man2<br />Road 1 goes to $road1<br />Road 2 goes to

function man1() {
global $man1,$man2,$road1,$road2;

In a group of 12 eggs only one is having weight less or more.
Can we have a program to find the egg, provided we have to weigh only three
times with a weighing machine with two pans,without using weights.

I think this program will work under the condition that the fault one is
heavier in weight, but the case is that it may be "lighter" OR "heavier".

Ok enough of php interview questions.
I need to pass a value to a function in .js file which has been linked in a
php file which in turn has been included in another php file.

------------------
//main.php
fetch DB values and store it in $param.
include"first.php"
------------------->

-------------------
//first.php
<script language='JavaScript' src='/myjs.js'>
</script>
------------------->

-------------------
myjs.js
function fun(param)
{
.... process with param
}
------------------->

How can I achieve this?
