如何在php中合并多个数组[重复]

Question

Array
(
    [0] => Array
        (
            [word] => you
            [phrase] => You will learn best from…
            [lang] => en
            [new] => tu
        )

    [1] => Array
        (
            [word] => why
            [phrase] => That is why LingQ has such a…
            [lang] => en
            [new] => por que
        )

)

并想在此处添加新值，例如

Array
(
    [0] => Array
        (
            [word] => you
            [phrase] => You will learn best from…
            [lang] => en
            [new] => tu
            [sometingnew] => new value here
        )

    [1] => Array
        (
            [word] => why
            [phrase] => That is why LingQ has such a…
            [lang] => en
            [new] => por que
            [sometingnew] => new value here
        )

)

请看[sometingnew] => new value here

这可能吗？

这是 csv 文件并在这里​​解析，我想添加一些新的值和选项，然后推送到 mysql 数据库中

像下面这样试试，

<?
 foreach($main_array as $key => $ma)
 {
  $main_array[$key]['sometingnew'] = 'new value here';
 }
?>

要删除特定的键及其值，

foreach ($main_array as $key => $ma) {
    unset($main_array[$key]['lang']);
   }
