$number should be exactly that a numeric value, what do you see if you

PHP Code:

what I mean is that we need to see the value of $number which is getting passed to that function.. so temp change the function to ..

PHP Code:

function prnintg($number){
      echo "\$number = {$number}";
      return number_format($number,0,'',',');
} 


that may or may not give us a clue to whats happening, you also need to find the part of the code that calls prnintg($someval)
