Should you not be comparing $left_operand with $right_operand here?

$output =bccomp($right_operand ,$right_operand);

As it is you are comparing $right_operand with $right_operand

 

Also you have the variables in the wrong way round in the echo statements

elseif ($output > 0){
echo $right_operand.' is biger then '.$left_operand;
}
else{
echo $left_operand.' is bigger then '.$right_operand ;
}

They should be the other way round. Quote from php.net

 

 

Return Values

Returns 0 if the two operands are equal, 1 if the left_operand is larger than the right_operand, -1 otherwise.

That is saying if $left_operand is greater then $right_operand it will return 1, otherwise it will return -1 if $right_operand is greater then $left_operand.
