php 陣列填充

Question

$oldArr = array(
array(
    0 => 'A0060750',
    1 => 9787560618852),
array(
    0 => '',
    1 => 9787560618855),
array(
    0 => '',
    1 => 9787560618856),
array(
    0 => 'A00607507',
    1 => 9787560618857),
array(
    0 => '',
    1 => 9787560618858)
);

轉化為

$newArr = array(
array(
    0 => 'A0060750',
    1 => 9787560618852),
array(
    0 => 'A0060750',
    1 => 9787560618855),
array(
    0 => 'A0060750',
    1 => 9787560618856),
array(
    0 => 'A00607507',
    1 => 9787560618857),
array(
    0 => 'A00607507',
    1 => 9787560618858)
);

简单说就是，如果二维数组中的，$oldArr[i][0] 的值为空，就以上一个不为空的值填充。
