Convert the file size to a user-friendly way, that is, display as "xxxgb", "xxxmb.

PHPCodeAs follows:

     Function My_formatsize ( $ Size  ){  $ Size = Doubleval ( $ Size  );  $ Rank = 0 ;  $ Rankchar = 'Bytes' ;  While ($ Size > 1024 ){  $ Size = $ Size /1024 ;  $ Rank ++ ;}  If ( $ Rank = 1 ){  $ Rankchar = "Kb" ;}  Else   If ($ Rank = 2 ){  $ Rankchar = "MB" ;}  Else   If ( $ Rank = 3 ){  $ Rankchar = "GB" ;}  $ Size = Number_format ( $ Size , 2 ,'.','' ); Return "". $ Size ."". $ Rankchar  ;} 

The javascript code is as follows:

 Function  My_formatsize ($ size ){  VaR Size = Parsefloat ($ size );  VaR Rank = 0 ;  VaR Rankchar = 'bytes' ;  While (Size> 1024) {Size = Size/1024; Rank ++ ;}  If (Rank = 1 ) {Rankchar = "Kb" ;}  Else   If (Rank = 2 ) {Rankchar = "MB" ;}  Else   If (Rank = 3 ) {Rankchar = "GB" ;} Return Size. tofixed (2) + "" + Rankchar ;}
