Answer 1

1. 使用 print_r 输出您的数组可读
2. array_unique 返回一个没有冗余值的数组 --> http://php.net/manual/en/function.array-unique.php

Answer 2

以下是 php.net 手册中的示例..

<?php
$input = array("a" => "green", "red", "b" => "green", "blue", "red");
$result = array_unique($input);
print_r($result);
?>
The above example will output:
Array
(
[a] => green
[0] => red
[1] => blue
)
