$c= $rows['table_name'];
$count_table=mysql_query("select count(*) from $c");
while(@$d=mysql_fetch_array($count_table)){
$e= $e+($d['count(*)']);

}
}

回复讨论(解决方案)

只会用笨办法了;

$a = 490766329;$b = 25115924452;echo number_format(floor($a*pow(10, -6))*pow(10, -2),2);echo number_format($b/pow(1024,3),2).'GB';

$sql = "select sum(TABLE_ROWS) as 记录数, sum(DATA_LENGTH+INDEX_LENGTH) as 占用空间 from information_schema.tables where table_schema='data'";$rs = mysql_query($sql);print_r(mysql_fetch_assoc($rs));
