working out file sizes xml

[graham23s]

Hi Guys,

 

finally got my code done for reading .xml files but when it comes to assigning the results back for the size into mb and gb i don't know what to do

 

this code:

 

     foreach($xml->{"file"} as $nfile) {
     
        $nposter = (string) trim($nfile['poster']);
        $nposter = ($nposter);
                    
        $ndate = 0 + trim($nfile['date']);
                    
        $nsubject = (string) trim($nfile['subject']);
        // To find num of segments in subject:
        $nsubjsegs = 0 + subj_seg($nsubject);
        
        // To find out if Par or not
        $npar = (stristr($nsubject, "par2")?0:1);
        
        $nsubject = ($nsubject);
                    
        $groups = array();
        foreach($nfile->groups->group as $group) {
              $groups[] = (string) trim($group);
        }
        
        $ngroups = (serialize($groups));
        
        $size = 0;
        foreach($nfile->segments->segment as $segment)
        $size += $segment['bytes'];
                          
      }

 

gives back this for the size:

 

52617506

 

can anyone tell me how to go about changing size into 1 more readable like in megabytes and gigabytes.

 

thanks guys
