Php多维数组获取值

Question

我有以下代码示例

private $analyze_types = array(
    "1" => array(
        'level' => '4',
        'l1' => '-1',
        'l2' => '-1',
        'l3' => '-1',
        'l4' => '-1',
        'l5' => '-1'
    ),
    "226" => array(
        'level' => '-1',
        'l1' => '-1',
        'l2' => '-1',
        'l3' => '2',
        'l4' => '3',
        'l5' => '4'
    )
);

我如何获得"1"的价值,如果我想获得"水平"价值,我该怎么办？

Answer 1

PHP:

foreach( $this->analyze_types as $key => $value) {
  echo $key; // output 1 and 226
  echo $value['level']; // output 4 and -1
}
