Question

这是我的问题，我有两个数组，一个是多维数组，第二个是单个数组，这些数组显示在两个表中。多数组显示在表1中，单数组显示在表2中。我要做的是计算每个职位的员工人数。

<?php include_once('fake_db.php'); ?>


<h3>Department List</h3>
<table class="table table-condensed table-striped table-bordered table-hover no-margin">
    <thead>
    <tr>
        <td>Name</td><td>Number of Employees</td><td>Action</td>
    </tr>
    </thead>
   <?php foreach($positions as $key => $value){ ?>

        <tr>
            <td><?= $value; ?></td>
            <td></td>
            <td><a href="profile.php?id=<?= $key; ?>">View Employee List</a></td>
        </tr>
    <?php } ?>
</table>

fake_db.php

$employees = array
             (
                 array("name" => 'Jason Alipala', "employee_id" => 'G1001-05', "position" => 1),
                 array("name" => 'Bryann Revina', "employee_id" => 'G1009-03', "position" => 2),
                 array("name" => 'Jeniel Mangahis', "employee_id" => 'G1009-04', "position" => 2),
                 array("name" => 'Arjay Bussala', "employee_id" => 'G1009-05', "position" => 3),
                 array("name" => 'Ronnel Ines', "employee_id" => 'G1002-06', "position" => 3)
             );

$positions = array(1 => 'TL', 2 => 'Programmer', 3 => 'Converter');

Answer 1

要计算每个职位的员工数量，可以在position数组的employees列上使用array_count_values。例如：

$emp_positions = array_count_values(array_column($employees, 'position'));
foreach ($positions as $key => $value) {
    echo $positions[$key] . ' : ' . $emp_positions[$key] . ' employees' . PHP_EOL;
}

输出：

TL : 1 employees 
Programmer : 2 employees 
Converter : 2 employees
