【唐诗】《蜀先主廟》 劉禹錫：天地英雄氣，千秋尚凜然。勢分三足鼎，業復五銖錢。得相能開國，生兒不象賢。淒涼蜀故妓，來舞魏宮前。

1. Review the existing implementation code below:

PHP

$data = $res['body']['data'];
print_r($data);
$data = array_combine(array_column($data, 'name'), $data);
print_r($data);
exit;

2. Check the print results of the multidimensional array before and after indexing. Use the value of the name column in the array as the new key. See Figure 1.

3. However, using only the array_column function is sufficient. When column_key is null, the entire array is returned (which is very useful when combined with the index_key parameter to re-index the array). There is no need to use the additional array_combine function.

PHP

$data = $res['body']['data'];
// print_r($data);
// $data = array_combine(array_column($data, 'name'), $data);
$data = array_column($data, null, 'name');
print_r($data);
exit;

4. Check the print results of the multidimensional array before and after indexing. The results match expectations. See Figure 2.
