<?php
$a=0;

$count=0;
$num=10;
 
while(num)
{
   $k = $a+$b;
   $a = $b;
   $b = $k;
   $count++;
while(k)

   if(k%i==0)
   echo 0;
}
   if(k==i)
   echo 1;
}
 
?>

You're not using variable in your while() loop at all. Also, you don't assign a value to $i, which should produce a division by zero error on every iteration of the loop. It's way too early for me to do math, but figure out what value to assign to $i, and make k and i variables in your while loop like so:

while($k){
	if($k%$i == 0){
		echo 0;
	}
	if($k == $i){
		echo 1;
	}
}
