php 替换二维数组的 key

php 替换二维数组中的 key

// 需要替换 key 的数组
$arr_old = array(
    \'0\' => array(\'id\' => 1, \'name\' => \'Carroll\'),
    \'1\' => array(\'id\' => 2, \'name\' => \'Chrdai\'),
    \'3\' => array(\'id\' => 3, \'name\' => \'xiaodai\'),
);

// 将新的key定义一个新数组
$key_name = array(\'key1\',\'key2\',\'key3\');

// 现在开始替换
$arr_new = array_combine($key_name,$arr_old);

var_dump($arr_new);
/*
array (size=3)
  \'key1\' =>
    array (size=2)
      \'id\' => int 1
      \'name\' => string \'Carroll\' (length=7)
  \'key2\' =>
    array (size=2)
      \'id\' => int 2
      \'name\' => string \'Chrdai\' (length=6)
  \'key3\' =>
    array (size=2)
      \'id\' => int 3
      \'name\' => string \'xiaodai\' (length=7)
