The previous section describes how to convert the number of bytes in java to KB, MB, GB, and TB. Here, PHP is used to implement this function. The code is very simple:

<? Phpfunction getFilesize ($ num) {$ p = 0; $ format = 'bytes '; if ($ num> 0 & $ num <1024) {$ p = 0; return number_format ($ num ). ''. $ format;} if ($ num >=1024 & $ num <pow (1024, 2) {$ p = 1; $ format = 'kb ';} if ($ num> = pow (1024, 2) & $ num <pow (1024, 3) {$ p = 2; $ format = 'mb ';} if ($ num> = pow (1024, 3) & $ num <pow (1024, 4) {$ p = 3; $ format = 'gb ';} if ($ num> = pow (1024, 4) & $ num <pow (1024, 5) {$ p = 3; $ forma T = 'tb';} $ num/= pow (1024, $ p); return number_format ($ num, 3 ). ''. $ format;} echo "test result from www.www.jb51.net: <br/>"; echo getFilesize (200 ). "<br/>"; echo getFilesize (20000 ). "<br/>"; echo getFilesize (2000000 ). "<br/>"; echo getFilesize (200000000 ). "<br/>"; echo getFilesize (20000000000 ). "<br/>"; echo getFilesize (2000000000000 ). "<br/>";?>

The running result is as follows:
