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 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);
