多维数组值每次消失的问题



我得到了未序列化的数组，但我正在努力从数组中获取值。我的数组如下:

我试图获得值与foreach循环代码:

$last_ext = '';
foreach ($arr['body'] as $items ){
$last_ext .= trim($items[0]['c']) . ' ' . trim($items[1]['c']); $last_ext .= "rn";}

运行代码后，只有第一个数组值的数据出现在输出中。其他数组值的数据没有传入。代码返回如下:

Attachment Points: 1 dorsal D-ring, 2 side positioning D-rings
Weight: 5.8 lbs. (2.6 kg)
ANSI Weight Capacity: 130-310 lbs. (59-141 kg)
OSHA Weight Capacity: Up to 420 lbs. (191 kg)
ANSI Standards: Z359.11-2021
OSHA Standards: 1926.502, 1910.140

我需要什么

如前所述，示例中的数据仅来自第一个数组。我无法从第二个或第三个数组中获取数据。 更Explanition

在'body'数组中有一个数组。这个1里有7个数组数组中。在这7个数组中有'body'数组。我需要提取数据0->c和1->c

更新我正在尝试获取下面的值代码，它获取值但是我如何将这些值合并到数组或其他地方

$spec1 = $ultray[0];
$spec2 = $ultray[1];
$spec3 = $ultray[2];
$spec4 = $ultray[3];
$spec5 = $ultray[4];
$spec6 = $ultray[5];
$spec7 = $ultray[6];
$spec8 = $ultray[7];
$spec9 = $ultray[8];

你的意思是:

$last_ext = '';
foreach ($arr['body'] as $items ){
foreach ($items as $i){
$last_ext .= trim($i['c']) . ' ';
}
$last_ext = trim($last_ext) . "rn";
}
