我有以下数组。
[rows] => Array
(
[0] => Array
(
[id] => 2704783858001796
[rowNumber] => 1
[expanded] => 1
[createdAt] => 2020-02-18T18:42:54Z
[modifiedAt] => 2020-02-18T22:07:36Z
[cells] => Array
(
[0] => Array
(
[columnId] => 1676391784703876
[value] => Approved
[displayValue] => Approved
)
[1] => Array
(
[columnId] => 1225963934640004
[value] => Submitted
[displayValue] => Submitted
)
[2] => Array
(
[columnId] => 4979307467564932
[value] => 2020-02-18
)
[3] => Array
(
[columnId] => 3203730339325828
其中[value]和[displayValue]并不总是显示。当我遍历数组时，我需要能够将[value]插入为空白或0。我不能让循环跳过键。
$j = count($dataID['rows']);
for ($i = 0; $i < $j; $i++) {
array_push($dataRows, array_column($dataID['rows'][$i]['cells'], 'value'));
}
如果两个键都不存在，则此代码循环遍历的每个元素，$dataID['row']并遍历的每个元素$row['cells']：
foreach( $dataID['rows'] as &$row ) {
foreach( $row['cells'] as &$cell ) {
if( !array_key_exists( 'value', $cell ) ) {
$cell['value'] = null;
}
if( !array_key_exists( 'displayValue', $cell ) ) {
$cell['displayValue'] = null;
}
}
}
这样的数组(short version of yours)：
Array
(
[rows] => Array
(
[0] => Array
(
[cells] => Array
(
[0] => Array
(
)
[1] => Array
(
)
)
)
)
)
成为：
Array
(
[rows] => Array
(
[0] => Array
(
[cells] => Array
(
[0] => Array
(
[value] =>
[displayValue] =>
)
[1] => Array
(
[value] =>
[displayValue] =>
)
)
)
)
)
