您能解释一下如何将一个数组值更改为第二个值吗。
请参阅以下示例。
第一个阵列
Array
(
[20239802] => one test
[20239801] => two testttttt
)
第二个阵列
Array (
[content] => Array (
[0] => Array (
[content_pack_id] => 10002
[content_pack_name] => 100 Days Of Love-FLA
[image_path] => Array ( [0] => pack_image_10002_width. )
[content_image_path] => Array ( [imgjpeg80] => http://content.jpg )
[content_id] => 20239802
[track] => Lede Inthati Santhosham
[duration] => 0
)
[1] => Array (
[content_pack_id] => 10003
[content_pack_name] => 1001 fdfdf
[image_path] => Array ( [0] => pack_image_10002_width. )
[content_image_path] => Array ( [imgjpeg80] => http://content.jpg )
[content_id] => 20239801
[track] => Lede Inthati Santhosham
[duration] => 0
)
)
[autoshuffle_pack] => no
)
如果第一阵列[20239802]与第二阵列[content_id] 匹配，我们需要替换第二阵列中的[track]值
需要输出：-
Array
(
[content] => Array
(
[0] => Array
(
[content_pack_id] => 10002
[content_pack_name] => 100 Days Of Love-FLA
[image_path] => Array
(
[0] => pack_image_10002_width.
)
[content_image_path] => Array
(
[imgjpeg80] => http://content.jpg
)
[content_id] => 20239802
[track] => one test
[duration] => 0
)
[1] => Array
(
[content_pack_id] => 10003
[content_pack_name] => 1001 fdfdf
[image_path] => Array
(
[0] => pack_image_10002_width.
)
[content_image_path] => Array
(
[imgjpeg80] => http://content.jpg
)
[content_id] => 20239801
[track] => two testttttt
[duration] => 0
)
)
[autoshuffle_pack] => no
)
检查[跟踪]价值变化在我的需求输出
按照dependent-first数组。
Array
(
[20239802] => one test
[20239801] => two testttttt
)
具有第二阵列
[content_id] => 20239801
[track] => two testttttt
这是你想要做的吗：
foreach($second_array as $key => $second_row) {
$content_id = $second_row['content_id'];
if(isset($first_array[$content_id]) && $first_array[$content_id] != '') {
$second_array['track'] = $first_array[$content_id];
}
}
您可以执行自己的函数。
第一个数组中的Foreach记录：
- 循环通过第二个并搜索
key == content_id - 如果匹配，则将
array2[$index][track]的值设置为array1[key] - 如果不是继续
您也可以使用array_search()函数更快地找到匹配，因为我将让您看看PHP文档
