uRealy Simple Question about variables

mrxxlphp

Can anyone tell me how I can show a variable with a unit. This is what im trying to get:

515Mbs

But if i use this then it treats the entire string as a variable and I dont want to leave a space between $number and Mbs.

$numberMbs

$number = 515;
echo $number . 'Mbs'; // outputs 515Mbs

  $size = 123456789; // in bytes
  $units = array(' B', ' KB', ' MB', ' GB', ' TB');
  for ($i = 0; $size > 1024; $i++) { $size /= 1024; }
  echo rtrim(number_format($size, 2, '.', ','), '.0').$units[$i];

Outputs: 117.74 MB
