Answer / joydeep
Given $a = 5;
$b = 'a';
So, $$b = $($b) = $a = 5
Simple, there is no concept of ASCII is applicable here....

Answer / jasmeet
Firstly wehave assigned that:
$a=5;
and now we have:
$b=a; //as it has said that $b= character 'a' whose ascii
value=95.
Now we need $$b;
so thw answer becomes:
$$b => $(95).
here 95 will again used as an ascii value and it will
call 'a'.
So the result comes out be 5.
not 100.
Check before writing any silly Question.

Answer / webguy
It would be great if you posy questions that are easy to
understand, something like,
Let's say:
$a = 5;
$b = 'a';
Now what's the value of $$b?
$bb = $a = 5;
so the answer is 5 and not 100.

because given
$a = 5
$b = 'a'
$$b = ?

hence, answer is 5.This ans is 100% correct,if anyone has
any doubt,jst contact me at ishika21114@gmail.com

If the $a is equal to 5 and $b is equal
to character a,so
$a=5;
$b="a";
$$b = $( $b ) = $ ( 'a' ) = $a = 5 ;
Of course Answer should be 5 !!

Answer / adeshsuryan
Correct format of this program is following check out this:
<?php
$a=5;
echo $b=a;
echo $$b;
?>
Dear Annonymus : You assign a constant in $$b not character.
your code is echo $b='a'."<br/>";
where 'a' treats as constant .but above a is a variable
keep this thing in mind.
