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 ("%. 2f TB", $

Storage Capacity Unit: Bit, Byte, KB, MB, GB, TB, PB, EB, ZB, YB, zbyb I recently read the Hadoop authoritative guide book, which has been designed by many organizations, However, my previous books seem to only teach GB, The current textbooks may be terabytes or petabytes of data, but I'm not sure. However, in the near future, there may be larger units that can be used, These days I 've been playing a b

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 1024, and two decimal places must be retaine

This article mainly introduces the PHP implementation of byte-byte conversion to KB, MB, GB, TB method, combined with an instance of PHP for the byte count of the conversion operation of the specific implementation method, involving the use of PHP mathematical operations related functions, the need for friends can refer to the next This article describes the PHP implementation of byte bytes converted to

When we choose VPS, Server host, we often see the common MB, GB, Mbps, and so on some of the labeling units. Most of us will probably know MB (megabytes), which is much larger than the amount of memory we often use. But if the bandwidth is involved in Mbps, it may be a bit difficult to understand, such as we often see that there is 2Mbps bandwidth, many people will understand that 2MB, and then use the file

In the computer newspaper, I saw that ABN Amro's 20 data centers have about 7PB of disk and more than 20PB of tape storage, and the annual 50%~70% growth of storage, So I want to see how big the PB is, and calculate the 27PB size of the hard disk about 400,000 80. 1Byte = 8 Bit (0,1) 1 KB = 1,024 Bytes (size of a shortcut) 1 MB = 1,024 KB = 1,048,576 Bytes (size

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

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 + +

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/1048576 * 100)/100. '

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

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: The code is as f

Using the FileSize () function command to achieve file size statistics, requires: 1, in GB, MB, KB, b in one output; 2.

Http://hi.baidu.com/dilijia1002/blog/item/38f0b5cef747c70d92457eb1.html Byte is a unit of measurement used by Computer Information Technology to measure storage capacity and transmission capacity. one byte equals to eight-bit binary. Currently, we usually use the smallest unit of computing storage space (in fact, there are smaller bit, 1 byte = 8 bit ). However, for hard disks or buckets, the minimum unit we use is KB (kilobyte), which is the 10th byt

A lot of people have been confused, "size" and "footprint (size on disk)" In a file or folder property usually do not match each other. The value of size represents the number of bytes in the actual size of the file, while the space-occupying value table file occupies the size of the hard disk space.This difference comes from the way the file system stores files on the drive. To reduce the number of addresses used, the file system treats a certain number of bytes as clusters. Depending on the fi

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
