middle, while the decimal calculation is not added.The following is a detailed list of conversions:The decimal algorithm:
1 kilobyte [KB] = (103) byte
1 megabyte [MB] = 1 (106) byte
1 gigabyte [GB] = 1 (109) byte
1 tera
file is greater than KB, or the smaller The function code is as follows

The size of the php statistics file, which is measured in GB, MB, KB, and B. 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 gr
I learned the fread reading command and used the filesize function. when I knew that this function was useful, I used it to compile the statistics file size function and used the filesize () function command to collect statistics on the file size, requirements: 1, with one output in GB, MB, KB, and B; 2. the order of magnitude must be greater than 1 and less than
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 )
BYTE (byte) is B: A byte is made up of 8-bit binary digits (1 byte = 8 bit). Byte is the most common base unit in the information store.
An English letter (case-insensitive) occupies a byte of space, a Chinese character occupies

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
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;
Commenced construction:

$len = FileSize ("1.RMVB");
$i = 4;
while ($i) {

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 >=
1. Bit is the smallest unit of data in a computer, and each bit can have a status of only 0 or 12. Byte (byte) 1Byte = 8 bit It is the basic unit of measurement for storage space, and 1byte can store an English letter or half Chinese characters. 3. The word consists of a number of bytes, the number of words is called word length, different grades of machines have different lengths. 8-bit machine: 1 words =
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:
