php - 如何使用PHP从字符串中删除一些字符

Question

我需要使用 PHP 按值从字符串搜索中删除一些字符。我在下面解释我的代码。

当前数据

$datArr = array(
    array(
        "name" => "Ram",
        "id" => 1,
        "date" => "12/04/2017 05:31:57 AM"
    ),
    array(
        "name" => "Rahim",
        "id" => 5,
        "date" => "12/03/2017 12:31:57 PM"
    ),
    array(
        "name" => "Raj",
        "id" => 4,
        "date" => "12/04/2017 05:31:57 PM"
    )
);

预期输出

$datArr = array(
    array(
        "name" => "Ram",
        "id" => 1,
        "date" => "12/04/2017 05:31:57"
    ),
    array(
        "name" => "Rahim",
        "id" => 5,
        "date" => "12/03/2017 12:31:57"
    ),
    array(
        "name" => "Raj",
        "id" => 4,
        "date" => "12/04/2017 05:31:57"
    )
);

从上面的数组中有一个 date 字段值，我需要使用 PHP 从所有日期中删除 AM/PM。

像这样使用 rtrim 删除尾字符，

$datArr = array_map(function($v){
    $v['date'] = rtrim($v['date'], " APMapm");
    return $v;
}, $datArr);
