Question

我有2个数组，一个数组包含员工信息，第二个数组包含员工销售。

对于“员工信息”数组，它包含ID和名称，而“员工销售”数组中包含ID和总销售额。

我尝试显示这2个数组，但是当我尝试仅显示2个数据时。

虽然我需要没有销售的ID也要显示。

我的代码：

<?php
$employees = [
    $i = [

        "id" => "1",
        "name" => "Aliff",
    ],
    $p = [

        "id" => "2",
        "name" => "Aina",
    ],
    $a = [

        "id" => "3",
        "name" => "Ana",
    ]
];
$employee_sales = [
    $i = [
        "id" => "1",
        "amount" => "500",
    ],
    $p = [
        "id" => "3",
        "amount" => "300",
    ],
];
?>
<!-- Next Table --->
<?php
// echo '<pre>';
// var_dump($employees);
// var_dump($employee_sales);
foreach ($employees as $employee) {
    foreach ($employee_sales as $employee_sale) {
        if ($employee['id'] == $employee_sale['id']) {
        ?>
        <table>
            <tr>
                <td><?= $employee['id']; ?></td>
                <td><?= $employee['name']; ?></td>
                <td><?= $employee_sale['amount']; ?></td>
            <tr>
        </table>
        <?php
        }
    }
}
?>
<!-- Next Table --->
<br>
<br>
<br>
<?php
foreach ($employees as $employee) {
?>
    <table>
        <tr>
            <td><?= $employee['id']; ?></td>
            <td><?= $employee['name']; ?></td>
        <tr>
    </table>
<?php } ?>
<!-- Next Table --->
<br>
<br>
<br>
<?php
foreach ($employee_sales as $employee_sale) {
?>
    <table>
        <tr>
            <td><?= $employee_sale['id']; ?></td>
            <td><?= $employee_sale['amount']; ?></td>
        <tr>
    </table>
<?php } ?>

即使该员工没有任何总销售额，我也希望显示其员工编号2。

由于员工没有任何销售，想显示amount = 0。

Answer 1

添加一个变量，该变量指示是否为该员工打印了任何销售记录。如果没有，则打印销售空的行。

foreach ($employees as $employee) {
    $sales_found = false;
    foreach ($employee_sales as $employee_sale) {
        if ($employee['id'] == $employee_sale['id']) {
        $sales_found = true;
?>
    <table>
    <tr>
    <td><?= $employee['id']; ?></td>
    <td><?= $employee['name']; ?></td>
    <td><?= $employee_sale['amount']; ?></td>
    <tr>
    </table>

<?php } 
    }
    if (!$sales_found) { ?>
        <table>
        <tr>
        <td><?= $employee['id']; ?></td>
        <td><?= $employee['name']; ?></td>
        <td>0</td>
        <tr>
        </table>

    <?php 
    } 
} ?>

Answer 2

请选中此一项。

<?php
 $employees = array(1=> array('id' => "1" , 'name' => 'Aliff')  ,2 => array('id' => "2" , 'name' => 'Aina'),3 => array('id' => "3" , 'name' => 'Ana')  );

  $employee_sales = array(1 => array('id' => "1" , 'amount' => '500')  ,2 => array('id' => "3" , 'amount' => '300'));

  $data = array();
 foreach ($employees as $key => $value) {

   $data[$value['id']] = $value['name'];

 }

   $data1 = array();
 foreach ($employee_sales as $key1 => $value1) {
    $data1[$value1['id']] = $value1['amount'];

 }



?>


    <table>
     <?php foreach ($data as $key => $value) {?>
     <?php if(isset($data1[$key])){?>
    <tr>
    <td><?= $key; ?></td>
    <td><?= $value; ?></td>
    <td><?= $data1[$key]; ?></td>
    <tr>
    <?php }else{?> 
     <tr>
    <td><?= $key; ?></td>
    <td><?= $value; ?></td>
    <td>0</td>
    <tr> 

    <?php } ?>

<?php } ?>


    </table>

Answer 3

首先，您可以重新索引阵列，以更轻松地按员工ID访问数据。另外，您可以在一个表中显示所有数据：

<table>
     <tr>
          <td>ID</td>
          <td>Name</td>
          <td>Amount</td>
     </tr>

<?php
    $employees = array_combine(array_column($employees, 'id'), $employees);
    $employee_sales = array_combine(array_column($employee_sales, 'id'), $employee_sales);

    foreach ($employees as $employeeId => $employee) {
?>
        <tr>
            <td><?= $employee['id']; ?></td>
            <td><?= $employee['name']; ?></td>
            <td><?= (isset($employee_sales[$employeeId]) ? $employee_sales[$employeeId]['amount'] : 0) ?></td>
        <tr>
<?php
    }
?>

</table>

<?php

$employees = [
    [
        "id" => "1",
        "name" => "Aliff",
    ],
    [
        "id" => "2",
        "name" => "Aina",
    ],
    [    
        "id" => "3",
        "name" => "Ana",
    ]
];

$employee_sales = [
    [
        "id" => "1",
        "amount" => "500",
    ],    
    [
        "id" => "3",
        "amount" => "300",
    ],        
];    

$id_sales = array_column($employee_sales, 'amount', 'id');
?>
<table>
    <thead>
        <tr>
            <th>id</th>
            <th>name</th>
            <th>sales</th>
        </tr>
    </thead>
    <tbody>
    <?php foreach ($employees as $employee) { ?>
        <tr>
            <td><?= $employee['id']; ?></td>
            <td><?= $employee['name']; ?></td>
            <td><?=
            isset($id_sales[$employee['id']]) 
                ? $id_sales[$employee['id']] 
                : '0' ?></td>
        </tr>
    <?php } ?>
    </tbody>
</table>

Answer 5

您可以在代码中使用以下循环。

<?php
foreach ($employees as $employee) {

?>
    <table>
    <tr>
    <td><?php echo $employee['id']; ?></td>
    <td><?php echo $employee['name']; ?></td>
    <td>
    <?php
        $key = array_search($employee['id'], array_column($employee_sales, 'id'));
        echo ( $key !== false ) ? $employee_sales[$key]['amount'] : 0;
    ?>
    </td>
    <tr>
    </table>

<?php
} ?>

array_search用于在employee_sales数组中查找匹配的employee_id的索引，该索引用于获取金额。如果找不到，则返回0

如何比较2个数组并将它们显示在一张表中
