php计算整个mysql数据库大小的方法,php计算mysql数据库

本文实例讲述了php计算整个mysql数据库大小的方法。分享给大家供大家参考。具体如下:

这里用MB,KB或者GB的格式返回计算结果。

function CalcFullDatabaseSize($database, $db) {
  $tables = mysql_list_tables($database, $db);
  if (!$tables) { return -1; }
  $table_count = mysql_num_rows($tables);
  $size = 0;
  for ($i=0; $i < $table_count; $i++) {
    $tname = mysql_tablename($tables, $i);
    $r = mysql_query("SHOW TABLE STATUS FROM ".$database." LIKE '".$tname."'");
    $data = mysql_fetch_array($r);
    $size += ($data['Index_length'] + $data['Data_length']);
  };
  $units = array(' B', ' KB', ' MB', ' GB', ' TB');
  for ($i = 0; $size > 1024; $i++) { $size /= 1024; }
  return round($size, 2).$units[$i];
}
/*
** Example:
*/
// open mysql connection:
$handle = mysql_connect('localhost', 'user', 'password'); 
if (!$handle) { die('Connection failed!'); }
// get the size of all tables in this database:
print CalcFullDatabaseSize('customer1234', $handle);
// --> returns something like: 484.2 KB
// close connection:
mysql_close($handle);

Copy after login

希望本文所述对大家的php程序设计有所帮助。
