不区分大小写的唯一多维数组循环 [英] Case insensitive unique multidimensional array loop

问题描述

我正在尝试遍历多维数组并获取唯一值（不区分大小写），有人可以帮助我吗？

I'm trying to loop through a multidimensional array and retreive unique values(case insensitive), can anyone help me?

$shop = array(
            array(
                'Title' => "General enquiries", 
                'Phone' => 02085237289,
            ),
            array(
                'Title' => "general enquiries", 
                'email' => '[e-mail]',
            ),
            array(
                'Title' => "not enquiries", 
                'Phone' => 02039303039,
            ),
            array(
                'Title' => "Not enquiries", 
                'email' => '[e-mail]',
            )
        );

这就是我要创建的内容：

This what i'm trying to create:

General Enquiries 
02085237289
[e-mail]

Not enquiries
[e-mail]
02039303039 

到目前为止我已经尝试过：

What I've tried so far:

$res = array();
foreach ($shop as $each) {
    array_push($res,strtolower($each['Title']));
    array_push($res,$each['email']);
    array_push($res,$each['Phone']);
}

$test =  array_unique($res);

foreach($test as $t){
    //echo $t;
}

推荐答案

我在最后要感谢拉斯克拉特和刘浩天。我以为我应该把它摆出来，以防人们好奇。
谢谢大家！

I figured things out in the end thanks to Rasclatt and Haotian Liu. I thought I should put it up just in case people were curious. Thanks guys!

我稍微改变了数组，看起来是这样的：

I changed the array a bit, this is how it looked:

Array
(
    [0] => Array
        (
            [contact_description] => Employment support
            [contact_type] => Phone
            [contact] => 0300 456 8110
        )

    [1] => Array
        (
            [contact_description] => General enquiries
            [contact_type] => Phone
            [contact] => 0300 456 8052
        )

    [2] => Array
        (
            [contact_description] => employment support
            [contact_type] => Email
            [contact] => [e-mail].u
        )

    [3] => Array
        (
            [contact_description] => general enquiries
            [contact_type] => Email
            [contact] => [e-mail]
        )

)

 $res = array();
 foreach ($shop as $each) {
      $lcValue = strtolower($each['Title']);
       if (isset($res[$lcValue]))
           array_push($res[$lcValue], $each['contact']);
       else
          $res[$lcValue] = array($each['contact']);
   }




foreach ($res as $name => $contact) {
                    echo '<h5 class="mb-0">' . ucwords($name) . '</h5>';
                    foreach ($contact as $contact) {
                        if (1 === preg_match('~[0-9]~', $contact)) {
                            // Phone Number
                            echo '<li class="work_number"><a href="tel:' . $contact . '">' . $contact . '</a></li>';
                        } elseif (strpos($contact, '@') !== false) {
                            //Email
                            echo '<li class="email"><a href="mailto:' . $contact . '" target="_blank">' . $contact . '</a></li>';
                        } else {
                            echo '<li><a>' . $contact . '</a></li>';
                        }
                    }

                }
