PHP怎么删除二维数组的空数组

$A[0][1] =$B[0];
$A[1][1] =$B[1];
$A[2][1] =$B[2];
$A[3][1] =$B[3];
$A[4][1] =$B[4];
......

$A[0][2] =$C[0];
$A[1][2] =$C[1];
$A[2][2] =$C[2];
$A[3][2] =$C[3];
$A[4][2] =$C[4];
......
如果取出的$B和$C的值为空，怎么删除相对应的$A?

Answer 1

foreac($A AS $v=>$k){
$bb = count($A);
for($i=0;$i++;$i<=$bb){
$cc = count($A[i]);
for($k=0;$k++;$k<=$cc){
if(!$A[i][k]){
unset($A[i][k]);
}
}
}
}
