php - 从数组中获取特定元素

Question

我有一个如下数组，我想从此数组中获取任何特定元素:数组存储在变量中。

   $results = 

        Array
           (
        [0] => stdClass Object
                         (
        [id] => 1
        [calendar] => 1
        [time] => 2016-01-22 17:25:28
        [booked_time] => 01/22/2016 11:00
        [booked_time_unformatted] => 2016-01-22 11:00:00
        [name] => Shoaib
        [email] => <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="bdced5d2dcd4dffdc9d8ded5d1d8dcd9c793ded2d0" rel="noreferrer noopener nofollow">[email protected]</a>
        [phone] => 0987654321
        [question] => 123
        [quantity] => 1
        [buffered_date] => a:9:{s:5:"PRICE";s:2:"25";s:10:"COUPONCODE";s:0:"";s:8:"QUANTITY";N;s:4:"NAME";s:6:"Shoaib";s:5:"EMAIL";s:20:"<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="9fecf7f0fef6fddfebfafcf7f3fafefbe5b1fcf0f2" rel="noreferrer noopener nofollow">[email protected]</a>";s:5:"PHONE";s:10:"0987654321";s:8:"COMMENTS";s:3:"123";s:4:"DATE";s:10:"01/22/2016";s:4:"TIME";s:5:"11:00";}
        [submitted] => 1
    )

[1] => stdClass Object
    (
        [id] => 2
        [calendar] => 1
        [time] => 2016-01-23 10:39:30
        [booked_time] => 01/25/2016 15:00
        [booked_time_unformatted] => 2016-01-25 15:00:00
        [name] => Shoaib
        [email] => <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a3d0cbccc2cac1e3d7c6c0cbcfc6c2c7d98dc0ccce" rel="noreferrer noopener nofollow">[email protected]</a>
        [phone] => 0987654321
        [question] => dsadasd
        [quantity] => 1
        [buffered_date] => a:9:{s:5:"PRICE";s:2:"25";s:10:"COUPONCODE";s:0:"";s:8:"QUANTITY";N;s:4:"NAME";s:6:"Shoaib";s:5:"EMAIL";s:20:"<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="9eedf6f1fff7fcdeeafbfdf6f2fbfffae4b0fdf1f3" rel="noreferrer noopener nofollow">[email protected]</a>";s:5:"PHONE";s:10:"0987654321";s:8:"COMMENTS";s:7:"dsadasd";s:4:"DATE";s:10:"01/25/2016";s:4:"TIME";s:5:"15:00";}
        [submitted] => 1
    )

[2] => stdClass Object
    (
        [id] => 3
        [calendar] => 1
        [time] => 2016-01-23 11:27:22
        [booked_time] => 01/25/2016 11:00
        [booked_time_unformatted] => 2016-01-25 11:00:00
        [name] => test
        [email] => <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="32415a5d535b50724657515a5e575356481c515d5f" rel="noreferrer noopener nofollow">[email protected]</a>
        [phone] => 0987654321
        [question] => asfas
        [quantity] => 1
        [buffered_date] => a:9:{s:5:"PRICE";s:2:"25";s:10:"COUPONCODE";s:0:"";s:8:"QUANTITY";N;s:4:"NAME";s:4:"test";s:5:"EMAIL";s:20:"<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="ea9982858b8388aa9e8f8982868f8b8e90c4898587" rel="noreferrer noopener nofollow">[email protected]</a>";s:5:"PHONE";s:10:"0987654321";s:8:"COMMENTS";s:5:"asfas";s:4:"DATE";s:10:"01/25/2016";s:4:"TIME";s:5:"11:00";}
        [submitted] => 0
    )

            )

现在我有一个像这样的数组，那么我如何获取该数组中[已提交] foreach 元素的值。

Answer 1

这不是一个数组。这是StdClass对象

访问 stdClass 中的信息

 $results[6]->submitted;
