This is a PHP program to get the size of the file and the file according to the size of the file display GB,MB,KB code code is very smart code, the code is as follows:
function Sizecount ($filesize) {
if ($filesize >= 1073741824) {
$filesize = Round ($filesize/1073741824 * 100)/100. ' GB ';
} elseif ($filesize >= 1048576) {
$filesize = Round ($filesize/1048
In a file-processing system, it is easy to get the size out of some system's own method, the problem is that the size is often just a byte B.If you want to convert this byte number to a KB, MB, GB final rendering to the user, it involves the arithmetic operation of dividing and taking the remainder.Here's how:public static String getprintsize (long size) {///If the number of bytes is less than 1024, it is d
Today in doing a network audit log when required to export the report, there is a mail attachment file size, the database is bytes byte number, the request to convert to KB display, use the following function, quite to the force, special to share.
function Sizeformat ($bytesize) {$i = 0;When the $bytesize is greater than 1024 bytes, start the loop, when the loop jumps to the 4th time;while (ABS ($bytesize) >=1024) {$bytesize = $bytesize/1024;$i + +;if ($i ==4) break;}The BYTES,KB,
For example, when we refer to "data transfer speed" and "hard disk storage space", kilobytes represent 1000 (103), and when it comes to memory or CPU cache capacity, kilobytes represent 1024 (210) because they are stored here by byte-code address.
In practical applications, we often need to convert bytecode to KB, MB, GB, and so on, where we use JavaScript to convert bytecode:

Today, I received an email from the Hotmail Member Service. It is said that there will be another change in Microsoft products.
In addition to increasing the size of the Hotmail inbox from 250 MB to 1 GB, Microsoft also launched the live series Windows Live Mail.
Windows Live Mail has the following features:

Exposure to computers all day, inevitably with a variety of measurement units to deal with, especially data, but you know bit, Byte, KB, GB, TB and so on all means how much data? Have you heard of EB, ZB, YB?
Bit (bit) is the initials of binary digit, the unit that measures information, and the smallest unit that represents the amount of content, only 0 or 12 binary states. 8 bits make up a byte (byte), can hold an English character, and a Chinese ch
Bit-----bit, bit, both of which can be said. It is the smallest unit of storage data in the computer.For example: 1111 1111 or 0000 0000 Each 1 or each 0 is a bit.byte--byte (denoted by B), which is the basic unit of computer storage capacity1 byte = 8 bit = "A" or "B"//is a letter of 26 letters anyway.2 byte = 1 Kanji =2 * 8=16 bit (this sentence can also be written in 2b=1 kanji =16 bit)Kb1 KB = 1024x768 byte (or write 1 KB = 1024x768 B)MB1 MB = 102
I learned the fread reading command and used the filesize function to compile the statistics file size function.

Using the FileSize () function command to achieve file size statistics, requires: 1, in GB, MB, KB, b in one output; 2. The order of magnitude must be greater than 1 and less than 1024, and two decimal places are reserved;

Legend has it that
1nib (nonabyte) = 1024yib, that is, the 90-power byte of 21dib (doggabyte) = 1024nib, that is, the 100 power byte of 21cib (corydonbyte) = 1024dib, that is, the 100 power byte of 2
Note: many materials on the Internet have reversed nib and DiB. NB is not the largest. dB is better than Nb. Haha! The bigger one is CB.

Php obtains the file size and converts the file size to gb, mb, and kb. this code uses the php program to obtain the file size and displays the file size as gb, mb, the code of kb code is very intelligent. the code is as follows:
Function sizecount ($ filesize ){
If ($ filesize> = 1073741824 ){
$ Filesize = round
Use the filesize () function command to calculate the file size. The value 1 must be an output of GB, MB, KB, and B. 2. the order of magnitude must be greater than 1 and less than 1024, and two decimal places must be retained;
Start:
Copy codeThe Code is as follows: $ len = filesize ("1. rmvb ");
$ I = 4;
While ($ I ){
If ($ out = $ len/pow (1024, $ I)> 1.0 | $ I = 1 ){
Switch ($ I ){
Case 4: {printf
Use the FileSize () function command to implement statistics for file size, requiring: 1, one output in GB, MB, KB, B, 2. The order of magnitude must be greater than 1 less than 1024 and retain two decimal places;
Commencement of construction:
Copy Code code as follows:
$len = FileSize ("1.RMVB");
$i = 4;
