Question

这可能是几个问题的重复。我有一个动态数组

Array
(
    [gender] => Male
    [age] => Array
        (
            [0] => 18-25 years
            [1] => 26-32 years
        )

    [name] => Nagesh
    [emailid] => nagesh@ccomsys.net
)

我希望将此数组存储在HTML表中作为一列中的键，将值存储在另一列中实施例。

__________________________________
Gender | Male
_______|__________________________
Age    | 18-25 years, 26-32 years
_______|__________________________
Name   | Nagesh
_______|__________________________
Email  | nagesh@ccomsys.net
_______|__________________________

我得到了关联数组的关键和值，但是我怎么能破坏年龄数组。

我试过下面的代码

$post = $this->request->post;
$age_array = array_column($post, 'age');
$age = '';

    foreach($post as $key => $value) {
        if($key == "age"){
            $age = implode(",", $age_array);
        }
        echo $age. "<br>";
        echo $key. "<br>";
        if($key != "age"){
            echo $value. "<br>";
        } else {
            echo $age;
        }
    }

谢谢你。

Answer 1

它的工作方式与您的期望相符：

foreach($post as $key => $value) {
        echo $key. "<br>";
        if($key == "age"){
                $age = implode(",", $post[$key]);
                echo $age. "<br>";                
        }
        if($key != "age"){
            echo $value. "<br>";
        } else {
            //echo $age;
        }
    }

如果你得到多个阵列意味着它会起作用。我改变了你的小事情：

foreach($post as $key => $value) {
        echo $key. "<br>";
        if(is_array($post[$key])){
                $age = implode(",", $post[$key]);
                echo $age. "<br>";

        }
        if(!is_array($post[$key])){
            echo $value. "<br>";
        } else {
            //echo $age;
        }
    }

Answer 2

只需进行一些小调整：

我将ucfirst()添加到第一列以匹配您想要的输出。
我使用内联条件来检查数组值是否为数组，以便在回显之前对数组进行适当的内爆。

代码：（Demo）

$post=[
    'gender'=>'Male',
    'age'=>['18-25 years','26-32 years'],
    'name'=>'Nagesh',
    'emailid'=>'nagesh@ccomsys.net'
];

echo '<table border=1>';
    foreach($post as $k=>$v){
        echo '<tr>';
            echo '<td>',ucfirst($k),'</td><td>',(is_array($v)?implode(', ',$v):$v),'</td>';
        echo '</tr>';
    }
echo '</table>';

未渲染的输出：

<table border=1>
    <tr>
        <td>Gender</td><td>Male</td>
    </tr>
    <tr>
        <td>Age</td><td>18-25 years, 26-32 years</td>
    </tr>
    <tr>
        <td>Name</td><td>Nagesh</td>
    </tr>
    <tr>
        <td>Emailid</td><td>nagesh@ccomsys.net</td>
    </tr>
</table>

通过runnable片段提供的渲染输出：

<table border=1><tr><td>Gender</td><td>Male</td></tr><tr><td>Age</td><td>18-25 years, 26-32 years</td></tr><tr><td>Name</td><td>Nagesh</td></tr><tr><td>Emailid</td><td>nagesh@ccomsys.net</td></tr></table>

Answer 3

替换以下代码：

if($key == "age"){
  $age = implode(",", $value);
}

与

public abstract class SomeBaseClass {}

public class SomeSpecificClass: SomeBaseClass {
    public int propertyA;
    public string propertyB;
}

public delegate void Callback<T>(T data);


public class Foo {


    void MethodA <T> (Callback<T> theInstance) where T: SomeBaseClass {
        MethodB(theInstance);
    }

    void MethodB(Callback<SomeBaseClass> theInstance) {

    }

    void MethodC() {
        Callback<SomeSpecificClass> cb = (data) => {};
        MethodA(cb);
    }

    void MethodD <T> (T theInstance) where T: SomeBaseClass {
        MethodE(theInstance);
    }

    void MethodE (SomeBaseClass theInstance) {

    }
}

Answer 4

您有一个数据数组，并且您希望将其显示在表格上。而不是使用implode（），为什么不将两个字符串连接在一起？

Array
(
    [gender] => Male
    [age] => Array
        (
            [0] => 18-25 years
            [1] => 26-32 years
        )

    [name] => Nagesh
    [emailid] => nagesh@ccomsys.net
)

PHP代码：

$post = $this->request->post;

foreach($post as $key => $value) {
  if($key == "age"){
    $age = $value[0].','.$value[1];
  }
  echo $age. "<br>";
  echo $key. "<br>";
  if($key != "age"){
    echo $value. "<br>";
  } else {
    echo $age;
  }
}

Answer 5

您需要编码如下......

foreach($post as $value){
    $gender = $value['gender'];
    $age = implode(',',$value['age']);
    $name = $value['name'];
    $email = $value['email'];
}

Answer 6

用这个改变你的foreach循环。

foreach($test as $key => $value) {
    $age = '';
    if($key == "age"){
        $age = implode(",", $value);
    }
    echo $age. "<br>";
    echo $key. "<br>";

    if($key != "age"){
        echo $value. "<br>";
    } else {
        echo $age;
    }
}
