Php 如何获取数组值

我想在视图文件的组合框中显示实用程序库中的数组值。 这是我的实用程序库代码

    class Utility
     {
   public $email_hooks = array(
    "create_user" => array(
            "name" => "New user creation",
            "keys" => array(
                "site_url" => "Site URL",
                "current_date" => "Curremt Date",
                "user_name" => "User name", 
                "name" => "Name of the user",
                "password" => "Password of user",
                "user_email"  => "Email address of new user"
            )               
        ),
    "register_user" => array(
            "name" => "New user registration",
            "keys" => array(
                "site_url" => "Site URL",
                "current_date" => "Curremt Date",
                "user_name" => "User name", 
                "name" => "Name of the user",
                "activation_url" => "Url for activation registered account",
                "user_email"  => "Email address of the user"
            )
        ),
    "forgot_password" => array(
            "name" => "Forgot Password",
            "keys" => array(
                "site_url" => "Site URL",
                "current_date" => "Curremt Date",
                "user_name" => "User name",
                "name" => "Name of the user",
                "reset_url" => "Url for resetting password",
                "user_email"  => "Email address of the user"
            )
        )
     );
   }

在视图部分，我只想在组合框中显示值“新建用户”、“新用户注册”和“忘记密码”

     <select id="choose">
        <option>-- Select One --</option>
        <?php
        foreach ($email_hooks as $key => $value)
        {
          foreach ($value as $value => $key)
          {
          echo '<option value="'.$key.'">'.$key.'</option>';
          }
        }
        ?>
        </select>
        <div class="col-lg-4" id="email_tmpl"></div>

这是控制器代码

    public function info()
{
$this->load->library('Utility');
$email_hooks = $this->utility->email_hooks;
$selected = isset($_POST['selected']) ? $_POST['selected'] : 'nothing';
//echo("This is $selected and other info");
foreach($email_hooks as $key=>$val)
{


    foreach($val['keys'] as $keys=>$value)
    {
        echo '%'.$keys.'%<br>';
    }
}

}

public function info（）
{
$this->load->library（'Utility'）；
$email\u hooks=$this->utility->email\u hooks；
$selected=isset（$_POST['selected']）？$_POST['selected']：'nothing'；
//echo（“这是$selected和其他信息”）；
foreach（$email_挂钩为$key=>$val）
{
foreach（$val['keys']作为$keys=>$value）
{
回显“%”。$keys.“%
”；
}
}
}

现在输出是

%站点url%
%当前日期%
%用户名%
%名称%
%密码%
%用户\u电子邮件%
%站点url%
%当前日期%
%用户名%
%名称%
%激活\u url%
%用户\u电子邮件%
%站点url%
%当前日期%
%用户名%
%名称%
%重置\u url%
%用户电子邮件%

我想要输出 %站点url%
%当前日期%
%用户名%
%名称%
%密码%
%用户_电子邮件%-用于创建新用户

%站点url%
%当前日期%
%用户名%
%名称%
%激活\u url%
%用户_电子邮件%-用于新用户注册

%站点url%
%当前日期%
%用户名%
%名称%
%重置\u url%
%用户\u电子邮件%-对于忘记密码的用户，请尝试以下操作：

foreach($email_hooks as $key=>$val){
    echo $val['name'];
}

您的选择框：

<select>
<option>-- Select One --</option>
 <?php 
foreach($email_hooks as $key=>$val){
    echo '<option value="'.$key.'">'.$val['name'].'</option>';
}
?>
 </select>

--选择一个--

看一看，您可以在下拉列表中获得所有值

$utility = new Utility();
   //print_r($utility->email_hooks);
   echo "<select>
     <option>-- Select One --</option>";

   foreach($utility->email_hooks as $key => $val){
      echo '<option value="">'.$val["name"].'</option>';
       foreach($val as $k=>$v){
          //    echo '<option value="">'.$v.'</option>';
            if(is_array($v)){
            foreach($v as $k1 => $v1){
                echo '<option value="">'.$v1.'</option>';
            }
            }

       }

   }

   echo "</select>";

$utility=new utility（）；
//打印（实用工具->电子邮件）；
回声“
--选择一个--“；
foreach（$utility->email_钩子为$key=>$val）{
回显'.$val[“name”].'；
foreach（$val为$k=>$v）{
//回音“.$v.”；
if（is_数组（$v））{
foreach（$v为$k1=>$v1）{
回音“.$v1.”；
}
}
}
}
回声“；

@Ann然后您可以通过单击检查图标接受答案。

$utility = new Utility();
   //print_r($utility->email_hooks);
   echo "<select>
     <option>-- Select One --</option>";

   foreach($utility->email_hooks as $key => $val){
      echo '<option value="">'.$val["name"].'</option>';
       foreach($val as $k=>$v){
          //    echo '<option value="">'.$v.'</option>';
            if(is_array($v)){
            foreach($v as $k1 => $v1){
                echo '<option value="">'.$v1.'</option>';
            }
            }

       }

   }

   echo "</select>";
