Php 为每个数据库记录创建链接

我试图为每一条记录建立单独的链接。 我有两个文件：

index.php

 <?php

$connect = mysql_connect("localhost", "test", "pass");
if (!$connect) {
    die("Can not connect:" . mysql_error());
}

mysql_select_db("snippets", $connect);

$ID = ''; 
if( isset( $_GET['ID'])) {
    $ID = $_GET['ID']; 
} 


$sql = "SELECT * FROM lectures";
$myData = mysql_query($sql, $connect);

while($record = mysql_fetch_array($myData)) {
$ID = $record['ID'];
$Name = $record['Name'];

    echo "<div class=\"container\">";
    echo "<div class=\"row\">";
        echo "<div class=\"col-md-2\">";
            echo "<p>$record[ID]</p>";
        echo "</div>";
        echo "<div class=\"col-md-2\">";
            echo "<p>$record[Topic]</p>";
        echo "</div>";
        echo "<div class=\"col-md-2\">";
            echo "<p>$record[Name]</p>";
        echo "</div>";
        echo "<div class=\"col-md-2\">";
            echo "<p>$record[Attendance]</p>";
        echo "</div>";
        echo "<div class=\"col-md-2\" style=\"display:none;\">";
            echo "<p>$record[Topic]</p>";
        echo "</div>";
        echo "<div class=\"col-md-2\" style=\"\">";
            echo "<td> <a href='car.php?id=" . $ID . " '>" . $record['Name'] . "</a> </td>";
        echo "</div>";
    echo "</div>";
    echo "</div>";


}

mysql_close($connect);

?>

<?php

$connect = mysql_connect("localhost", "test", "pass");
if (!$connect) {
    die("Can not connect:" . mysql_error());
}

mysql_select_db("snippets", $connect);



$ID = ''; 
if( isset( $_GET['ID'])) {
    $ID = $_GET['ID']; 
} 

$sql = "SELECT * FROM lectures WHERE ID = '$ID' ";
$myData = mysql_query($sql, $connect);

while($record = mysql_fetch_array($myData)) {
$ID = $record['ID'];
$Name = $record['Name'];

    echo "<div class=\"container\">";
    echo "<div class=\"row\">";
        echo "<div class=\"col-md-2\">";
            echo "<p>$record[ID]</p>";
        echo "</div>";
        echo "<div class=\"col-md-2\">";
            echo "<p>$record[Topic]</p>";
        echo "</div>";
        echo "<div class=\"col-md-2\">";
            echo "<p>$record[Name]</p>";
        echo "</div>";
        echo "<div class=\"col-md-2\">";
            echo "<p>$record[Attendance]</p>";
        echo "</div>";
        echo "<div class=\"col-md-2\" style=\"display:none;\">";
            echo "<p>$record[Topic]</p>";
        echo "</div>";

    echo "</div>";
    echo "</div>";


}

mysql_close($connect);

?>

和car.php

 <?php

$connect = mysql_connect("localhost", "test", "pass");
if (!$connect) {
    die("Can not connect:" . mysql_error());
}

mysql_select_db("snippets", $connect);

$ID = ''; 
if( isset( $_GET['ID'])) {
    $ID = $_GET['ID']; 
} 


$sql = "SELECT * FROM lectures";
$myData = mysql_query($sql, $connect);

while($record = mysql_fetch_array($myData)) {
$ID = $record['ID'];
$Name = $record['Name'];

    echo "<div class=\"container\">";
    echo "<div class=\"row\">";
        echo "<div class=\"col-md-2\">";
            echo "<p>$record[ID]</p>";
        echo "</div>";
        echo "<div class=\"col-md-2\">";
            echo "<p>$record[Topic]</p>";
        echo "</div>";
        echo "<div class=\"col-md-2\">";
            echo "<p>$record[Name]</p>";
        echo "</div>";
        echo "<div class=\"col-md-2\">";
            echo "<p>$record[Attendance]</p>";
        echo "</div>";
        echo "<div class=\"col-md-2\" style=\"display:none;\">";
            echo "<p>$record[Topic]</p>";
        echo "</div>";
        echo "<div class=\"col-md-2\" style=\"\">";
            echo "<td> <a href='car.php?id=" . $ID . " '>" . $record['Name'] . "</a> </td>";
        echo "</div>";
    echo "</div>";
    echo "</div>";


}

mysql_close($connect);

?>

<?php

$connect = mysql_connect("localhost", "test", "pass");
if (!$connect) {
    die("Can not connect:" . mysql_error());
}

mysql_select_db("snippets", $connect);



$ID = ''; 
if( isset( $_GET['ID'])) {
    $ID = $_GET['ID']; 
} 

$sql = "SELECT * FROM lectures WHERE ID = '$ID' ";
$myData = mysql_query($sql, $connect);

$ID = $record['ID'];
$Name = $record['Name'];

    echo "<div class=\"container\">";
    echo "<div class=\"row\">";
        echo "<div class=\"col-md-2\">";
            echo "<p>$record[ID]</p>";
        echo "</div>";

        echo "</div>";
        echo "<div class=\"col-md-2\">";
            echo "<p>$record[Name]</p>";
        echo "</div>";
        echo "<div class=\"col-md-2\">";

mysql_close($connect);

当我点击链接时，页面是空的。如果我在

ID='2'

中输入一个值（例如：2），它就会工作。但这将是所有链接的值。

如果您在linux中工作，您应该在大写字母中编写您的

ID

参数，因此您应该替换此：

echo "<td> <a href='car.php?id=" . $ID . " '>" . $record['Name'] . "</a> </td>";

echo”“；

据此：

echo "<td> <a href='car.php?ID=" . $ID . " '>" . $record['Name'] . "</a> </td>";

echo”“；

请不要再使用

mysql.*

函数，因为它们已被弃用，并且在新发布的PHP7.0中已被删除。使用或。另外，在处理用户输入使用时，这使您的查询在SQL注入时更加安全。请参考以下链接，并将其应用到您的代码中。我使用phpmyadminLinux与PHP字母大小写语法无关。这仅适用于文件/文件夹命名约定。这不是我的下一票。顺便说一句，URL通常区分大小写（机器名除外）。可能有URL，或URL的一部分，其中大小写无关紧要，但识别这些可能并不容易。用户应该始终认为URL是区分大小写的。
