Question

我试图在while回音中回显我的PHP html循环。

基本上，我想在另一个回声中回声。这可能吗？

这是我的代码：

<?php

session_start();
require 'config.php';

if (@$_SESSION['username']) {

    $query = "SELECT * FROM `crew_info`";
    $query_run = mysqli_query($conn,$query);

    echo '<!DOCTYPE html>
    <html>
    <head>
        <title>All Crew</title>
    </head>
    <body>

        <table>
            <tr>
                <th>First Name: </th>
                <th>Middle Name: </th>
                <th>Last Name: </th>
                <th>Age: </th>
                <th>Birth Date: </th>
                <th>Birth Place: </th>
                <th>Gender: </th>
                <th>Martial Status: </th>
                <th>Nationality: </th>
                <th>Email Address: </th>
                <th>Address 1: </th>
                <th>Address 2: </th>
                <th>Course: </th>
                <th>School Graduated: </th>
                <th>Remarks: </th>
                <th>Date Added: </th>
                <th>Status: </th>
            </tr>
            <tr>
            while($record = mysqli_fetch_assoc($query_run)) {
            echo "<tr>";
            echo "<th>".$record['first_name']."</th>";
            echo "<th>".$record['middle_name']."</th>";
            echo "<th>".$record['last_name']."</th>";
            echo "<th>".$record['age']."</th>";
            echo "<th>".$record['birth_date']."</th>";
            echo "<th>".$record['birth_place']."</th>";
            echo "<th>".$record['gender']."</th>";
            echo "<th>".$record['martial_status']."</th>";
            echo "<th>".$record['nationality']."</th>";
            echo "<th>".$record['email_address']."</th>";
            echo "<th>".$record['address_1']."</th>";
            echo "<th>".$record['address_2']."</th>";
            echo "<th>".$record['course']."</th>";
            echo "<th>".$record['school_graduated']."</th>";
            echo "<th>".$record['remarks']."</th>";
            echo "<th>".$record['date_added']."</th>";
            echo "<th>".$record['crew_status']."</th>";
        echo "</tr><br>";
            </tr>
        </table>

    </body>
    </html>';
    }    
}
else {
    header('Location: /practice1/index.php');
}

?>

我希望有人可以帮助我

将您的代码更改为：

echo '<!DOCTYPE html>
    <html>
    <head>
        <title>All Crew</title>
    </head>
    <body>

        <table>
            <tr>
                <th>First Name: </th>
                <th>Middle Name: </th>
                <th>Last Name: </th>
                <th>Age: </th>
                <th>Birth Date: </th>
                <th>Birth Place: </th>
                <th>Gender: </th>
                <th>Martial Status: </th>
                <th>Nationality: </th>
                <th>Email Address: </th>
                <th>Address 1: </th>
                <th>Address 2: </th>
                <th>Course: </th>
                <th>School Graduated: </th>
                <th>Remarks: </th>
                <th>Date Added: </th>
                <th>Status: </th>
            </tr>
            <tr>';
            while($record = mysqli_fetch_assoc($query_run)) {
            echo "<tr>";
            echo "<th>".$record['first_name']."</th>";
            echo "<th>".$record['middle_name']."</th>";
            echo "<th>".$record['last_name']."</th>";
            echo "<th>".$record['age']."</th>";
            echo "<th>".$record['birth_date']."</th>";
            echo "<th>".$record['birth_place']."</th>";
            echo "<th>".$record['gender']."</th>";
            echo "<th>".$record['martial_status']."</th>";
            echo "<th>".$record['nationality']."</th>";
            echo "<th>".$record['email_address']."</th>";
            echo "<th>".$record['address_1']."</th>";
            echo "<th>".$record['address_2']."</th>";
            echo "<th>".$record['course']."</th>";
            echo "<th>".$record['school_graduated']."</th>";
            echo "<th>".$record['remarks']."</th>";
            echo "<th>".$record['date_added']."</th>";
            echo "<th>".$record['crew_status']."</th>";
            echo '</tr>';
          }
         echo '</table>

    </body>
    </html>';

Answer 2

回声中没有回声...

不

  echo ' aaa echo "bbbb"; ccccc ';

可是：

echo ' aaa ';
echo "bbbb"; 
echo 'ccccc ';

所以你的代码看起来会是：

echo '<!DOCTYPE html>
    <html>
    <head>
        <title>All Crew</title>
    </head>
    <body>

        <table>
            <tr>
                <th>First Name: </th>
                <th>Middle Name: </th>
                <th>Last Name: </th>
                <th>Age: </th>
                <th>Birth Date: </th>
                <th>Birth Place: </th>
                <th>Gender: </th>
                <th>Martial Status: </th>
                <th>Nationality: </th>
                <th>Email Address: </th>
                <th>Address 1: </th>
                <th>Address 2: </th>
                <th>Course: </th>
                <th>School Graduated: </th>
                <th>Remarks: </th>
                <th>Date Added: </th>
                <th>Status: </th>
            </tr>
            <tr>';
            while($record = mysqli_fetch_assoc($query_run)) {
            echo "<tr>";
            echo "<th>".$record['first_name']."</th>";
            echo "<th>".$record['middle_name']."</th>";
            echo "<th>".$record['last_name']."</th>";
            echo "<th>".$record['age']."</th>";
            echo "<th>".$record['birth_date']."</th>";
            echo "<th>".$record['birth_place']."</th>";
            echo "<th>".$record['gender']."</th>";
            echo "<th>".$record['martial_status']."</th>";
            echo "<th>".$record['nationality']."</th>";
            echo "<th>".$record['email_address']."</th>";
            echo "<th>".$record['address_1']."</th>";
            echo "<th>".$record['address_2']."</th>";
            echo "<th>".$record['course']."</th>";
            echo "<th>".$record['school_graduated']."</th>";
            echo "<th>".$record['remarks']."</th>";
            echo "<th>".$record['date_added']."</th>";
            echo "<th>".$record['crew_status']."</th>";
            echo '</tr>';
          }
         echo '</table>

或类似于:(注意; while环上方的tr也必须删除，因为while循环中已有一个。

<?php
$loop = "";
while ($record = mysqli_fetch_assoc($query_run)) {
    $loop .= "<tr>";
    $loop .= "<th>" . $record['first_name'] . "</th>";
    $loop .= "<th>" . $record['middle_name'] . "</th>";
    $loop .= "<th>" . $record['last_name'] . "</th>";
    $loop .= "<th>" . $record['age'] . "</th>";
    $loop .= "<th>" . $record['birth_date'] . "</th>";
    $loop .= "<th>" . $record['birth_place'] . "</th>";
    $loop .= "<th>" . $record['gender'] . "</th>";
    $loop .= "<th>" . $record['martial_status'] . "</th>";
    $loop .= "<th>" . $record['nationality'] . "</th>";
    $loop .= "<th>" . $record['email_address'] . "</th>";
    $loop .= "<th>" . $record['address_1'] . "</th>";
    $loop .= "<th>" . $record['address_2'] . "</th>";
    $loop .= "<th>" . $record['course'] . "</th>";
    $loop .= "<th>" . $record['school_graduated'] . "</th>";
    $loop .= "<th>" . $record['remarks'] . "</th>";
    $loop .= "<th>" . $record['date_added'] . "</th>";
    $loop .= "<th>" . $record['crew_status'] . "</th>";
    $loop .= '</tr>';
}

$out = '<!DOCTYPE html>
    <html>
    <head>
        <title>All Crew</title>
    </head>
    <body>
        <table>
            <tr>
                <th>First Name: </th>
                <th>Middle Name: </th>
                <th>Last Name: </th>
                <th>Age: </th>
                <th>Birth Date: </th>
                <th>Birth Place: </th>
                <th>Gender: </th>
                <th>Martial Status: </th>
                <th>Nationality: </th>
                <th>Email Address: </th>
                <th>Address 1: </th>
                <th>Address 2: </th>
                <th>Course: </th>
                <th>School Graduated: </th>
                <th>Remarks: </th>
                <th>Date Added: </th>
                <th>Status: </th>
            </tr>';

echo $out . $loop . '</table>
    </body>
    </html>';
