昨天排序列错了，再发次，请高手帮忙排序。

$fields[0][0]=array('d','3');
$fields[0][1]=array('d','3');
$fields[0][2]=array('d','3');
$fields[0][3]=array('d','3');

$fields[1][0]=array('d','2');
$fields[1][1]=array('d','2');
$fields[1][2]=array('d','2');
$fields[1][3]=array('d','2');

$fields[2][0]=array('d','6');
$fields[2][1]=array('d','6');
$fields[2][2]=array('d','6');
$fields[2][3]=array('d','6');

$fields[3][0]=array('b','5');
$fields[3][1]=array('b','5');
$fields[3][2]=array('b','5');
$fields[3][3]=array('b','5);

$fields[4][0]=array('b','4');
$fields[4][1]=array('b','4');
$fields[4][2]=array('b','4');
$fields[4][3]=array('b','4');

$fields[5][0]=array('b','1');
$fields[5][1]=array('b','1');
$fields[5][2]=array('b','1');
$fields[5][3]=array('b','1');

$fields[6][0]=array('c','8');
$fields[6][1]=array('c','8');
$fields[6][2]=array('c','8');
$fields[6][3]=array('c','8);

$fields[7][0]=array('c','9');
$fields[7][1]=array('c','9');
$fields[7][2]=array('c','9');
$fields[7][3]=array('c','9');

$fields[8][0]=array('c','7');
$fields[8][1]=array('c','7');
$fields[8][2]=array('c','7');
$fields[8][3]=array('c','7');

如何排序，排序方式为：先按array('c','7')这里的字母排序，然后字母排序的基础上，再按array里的数字大小排序。排序结果如下：
$fields[0][0]=array('b','1');
$fields[0][1]=array('b','1');
$fields[0][2]=array('b','1');
$fields[0][3]=array('b','1');

$fields[1][0]=array('b','4');
$fields[1][1]=array('b','4');
$fields[1][2]=array('b','4');
$fields[1][3]=array('b','4');

$fields[2][0]=array('b','5');
$fields[2][1]=array('b','5');
$fields[2][2]=array('b','5');
$fields[2][3]=array('b','5');

$fields[3][0]=array('c','7');
$fields[3][1]=array('c','7');
$fields[3][2]=array('c','7');
$fields[3][3]=array('c','7');

$fields[4][0]=array('c','8');
$fields[4][1]=array('c','8');
$fields[4][2]=array('c','8');
$fields[4][3]=array('c','8);

$fields[5][0]=array('c','9');
$fields[5][1]=array('c','9');
$fields[5][2]=array('c','9');
$fields[5][3]=array('c','9');

$fields[6][0]=array('d','2');
$fields[6][1]=array('d','2');
$fields[6][2]=array('d','2');
$fields[6][3]=array('d','2');

$fields[7][0]=array('d','3');
$fields[7][1]=array('d','3');
$fields[7][2]=array('d','3');
$fields[7][3]=array('d','3');

$fields[8][0]=array('d','6');
$fields[8][1]=array('d','6');
$fields[8][2]=array('d','6');
$fields[8][3]=array('d','6');

上次有高手，给我了一个排序方法，但是只是排其中一个的，谁能把２个排序的做出来下给我。
uasort($fields, create_function('$a,$b','return $a[key($a)][0]==$b[key($b)][0]?0:(($a[key($a)][0]>$b[key($b)][0])?1:-1);'));
