データベースから最新のレコードを取得する方法

Question

このようなデータベースから最新のジョブを10件表示する方法。 Please click here to see image

私はこれまでに次のコードを書いています。

$query = "SELECT * FROM jobs ORDER BY posting_date DESC LIMIT 10"; 

$query = mysqli_query($conn, $query); 

while ($row = mysqli_fetch_assoc($query)) { 


    $job_title = row["job_title"]; 
    $company_name = $row["company_name"]; 
    $department = $row["department"]; 
    $location = $row["location"]; 
    $job_type = $row["job_type"]; 
    $job_description = $row["job_description"]; 
    $posting_date = date('d-m-y'); 

} 

$ rowは、データベースからすべての列を返します。私は4つの役職、会社名、場所と日付だけを望む

Answer 1

選択クエリで列名を使用します。

$query = "SELECT job_title,company_name,location,posting_date FROM jobs ORDER BY posting_date DESC LIMIT 10"; 
$query = mysqli_query($conn, $query); 

echo "<table>"; 
echo "<tr> <th>Job Title</th> <th>Company Name</th> <th>Location</th> <th>Date Posted</th> </tr>"; 
echo "<tbody>"; 
while($row = mysqli_fetch_assoc($query)) { 
    $job_title = $row["job_title"]; 
    $company_name = $row["company_name"]; 
    $department = $row["department"]; 
    $location = $row["location"]; 
    $posting_date = date('d-m-y', strtotime($row['posting_date'])); 

    echo "<tr>"; 
    echo "<td>".$job_title."</td>"; 
    echo "<td>".$company_name."</td>"; 
    echo "<td>".$location."</td>"; 
    echo "<td>".$posting_date."</td>"; 
    echo "<tr>"; 
} 
echo "</tbody>"; 
echo "</table>";

    echo "<td>$row['job_title']</td>"; 
    echo "<td>$row['company_name']</td>";
