Rule of mathematics - you cannot divide by by zero.

 

Check the value is not zero before attempting to divide by it. The error message is quite straight forward.

What do you want US to do about it?  You didn't even show us the line that is giving you the error.

I don't have enough knowledge of php.

You could do something like this to set the rate to 0 if it's going to attempt to divide by 0.

 

$rate = $tek[0][1] != 0 ? $tek[0][0] / $tek[0][1] : 0;

 

But, you may wish to just return 0 if it's not going to work.

 

if ($tek[0][1] == 0)
    return 0;

$rate = $tek[0][0] / $tek[0][1];
