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", $ out); break ;} Case 3: {prin

PHP implements the original method of converting Byte to KB, MB, GB, and TB. This example describes how to convert the number of bytes in PHP to KB, MB, GB, or TB. We will share this with you for your reference. The details are as follows: The previous section describes how to convert the number of bytes in java to KB, MB, GB, and TB.

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"); $i = 4; while ($i) { if ($out = $len/pow (1024, $i) >1.0| | $i ==1) { Switch ($i) { Case 4: {printf ("%.2f TB", $out); Case 3: {

Do you know how much data the bit, Byte, KB, GB, TB, etc. all mean? Have you ever heard of Pb, EB, ZB, YB? Bit (bit) is the English abbreviation of binary digit, the unit of measuring information, is also the smallest unit that represents the quantity, only 0, 12 kinds of binary states. The 8 bit consists of a byte (byte) that can hold an English character. A Chinese character requires two bytes of storage space, and ordinary English words require abo

Starting from 10 Gb, oracle began to provide Shrink commands. If our tablespace supports automatic segment space management (ASSM), we can use this feature to narrow down the segment, that is, reduce the HWM. Here we need to emphasize that this new 10g feature is only valid for the ASSM tablespace, otherwise the ORA-10635: Invalid segment or tablespace type will be reported. Here, we will discuss how to recycle wasted space for an ASSM segment. Simila
