首先我对我的英语说抱歉..
我必须在多维数组中的所有子数组的第一个位置插入一个元素..
$docNum = "RT/2013-2014/0266";
$values =
Array
(
[0] => Array
(
[0] => 2014-08-07
[1] => Dl-Dis1
[2] => Discount
[3] => 7.500
[4] => 26.25
)
[1] => Array
(
[0] => 2014-08-07
[1] => Dl-Dis1
[2] => Discount
[3] => 7.500
[4] => 24.38
)
)
这两个是输入..
我给组合的代码是
array_unshift($values, $docNum);
我的输出是
Array
(
[0] => RT/2013-2014/0266
[1] => RT/2013-2014/0266
[2] => Array
(
[0] => 2014-08-07
[1] => Dl-Dis1
[2] => Discount
[3] => 7.500
[4] => 26.25
)
[3] => Array
(
[0] => 2014-08-07
[1] => Dl-Dis1
[2] => Discount
[3] => 7.500
[4] => 24.38
)
)
我想要的输出应该是
Array
(
[0] => Array
(
[0] => RT/2013-2014/0266
[1] => 2014-08-07
[2] => Dl-Dis1
[3] => Discount
[4] => 7.500
[5] => 26.25
)
[1] => Array
(
[0] => RT/2013-2014/0266
[1] => 2014-08-07
[2] => Dl-Dis1
[3] => Discount
[4] => 7.500
[5] => 24.38
)
)
我想你明白我在问什么..
而且我已经看到这个[链接]:(stackoverflow.com/questions/15398678/array-unshift-for-multidimensional-arrays)
请不要标记为重复..
先谢谢你..
最佳答案
您不能完全取消移动它。这将在父数组而不是子数组上添加值。您可以先循环它，然后循环每个子数组，然后使用 unshift。示例:
// generate the string with the value you'd unshift
$docNum = "RT/2013-2014/0266";
// build up your multidimensional array
$values = array(
array('2014-08-07', 'Dl-Dis1', 'Discount', 7.500, 26.25),
array('2014-08-07', 'Dl-Dis1', 'Discount', 7.500, 24.38),
);
// for every sub-array...
foreach($values as &$sub_array) { // & reference
// ... unshift your value
array_unshift($sub_array, $docNum);
}
echo '<pre>';
// check out the result
print_r($values);
输出如下:
Array
(
[0] => Array
(
[0] => RT/2013-2014/0266
[1] => 2014-08-07
[2] => Dl-Dis1
[3] => Discount
[4] => 7.5
[5] => 26.25
)
[1] => Array
(
[0] => RT/2013-2014/0266
[1] => 2014-08-07
[2] => Dl-Dis1
[3] => Discount
[4] => 7.5
[5] => 24.38
)
)
