Answer 1

To see the contents of array you can use.

(要查看可以使用的数组内容 。)

1) print_r($array);

(1） print_r($array);)

or if you want nicely formatted array then:

(或者如果你想要格式良好的数组，那么：)

echo '<pre>'; print_r($array); echo '</pre>';

2) use var_dump($array) to get more information of the content in the array like datatype and length.

(2）使用var_dump($array)获取数组内容的更多信息，如数据类型和长度。)

3) you can loop the array using php's foreach();

(3）你可以使用php的foreach();循环数组foreach();)

and get the desired output.

(并获得所需的输出。)
