Question

我想显示用户数据，假设如下所示。

 <?php session_start() ?>
 <form method="post" action="">
 <input type="text" name="name"/>
 <input type="text" name="mobile"/>
 <input type="submit" name="submit"/>
 </form>

 <?php
 $_SESSION['name']=$_POST['name'];
 $_SESSION['mobile']=$_POST['mobile'];

现在我不想将这些值存储在数据库中，而是在下面的表格中显示值

S.NO NAME MOBILE 1 Yogesh 9717797354 2 BHASKAR 9898225441 3 ANIKESH 9594474557 4 ABHISHEK 9854774144

现在我要显示每个名字和在没有使用会话存储在数据库中的情况下，如下所示在表中移动没有输入。我已尝试但只能插入单个值，并插入其更新现有值旁边。怎么能用lop实现呢？请帮忙?? o

Answer 1

Session可以存储数据数组，因此您可以执行以下操作：

＆＃13;

<?php
    session_start();
    $contact = array(
        "1" => array("Yogesh" => "9717797354"),
        "2" => array("BHASKAR" => "9898225441"),
        "3" => array("ANIKESH" => "9594474557"),
        "3" => array("ABHISHEK" => "9854774144"),
    );
    
    $_SESSION["contact"] = $contact;
    $cl = $_SESSION["contact"];

    foreach ($cl as $pos => $info) {
        foreach ($info as $name => $number) {
            echo $pos.": ".$name.": ".$number."</br>";
        }
    }
?>

＆＃13;

每次有人添加新联系人时，您都可以附加此数组。像这样：

＆＃13;

<?php
    session_start();
    $contact = array(
        "Yogesh" => "9717797354",
        "BHASKAR" => "9898225441",
        "ANIKESH" => "9594474557",
        "ABHISHEK" => "9854774144",
    );
    
    // Load the predifined list if not already loaded
    if (!isset($_SESSION["contact"])) {
        $_SESSION["contact"] = $contact;
    }

    // if new contact added
    if ($_SERVER["REQUEST_METHOD"] == "POST") {
        if (isset($_POST["name"]) && isset($_POST["mobile"])) {
            if (isset($_POST["name"]) && isset($_POST["mobile"])) {
                $name = $_POST["name"];
                $number = $_POST["mobile"];
                $appendArray = array(
                    $name => $number
                );

                // create new array by merging the existing one and the new data.
                $newList = array_merge($_SESSION["contact"], $appendArray);
                $_SESSION["contact"] = $newList;
            }
        }
    }
?>

<table>
  <tr>
    <th>S.NO</th>
    <th>NAME</th>
    <th>MOBILE</th>
  </tr>
  <?php
    $cl = $_SESSION["contact"];
    $size = 0;
    foreach ($cl as $name => $number) {
  ?>
    <tr>
      <td><?php echo ++$size; ?></td>
      <td><?php echo $name; ?></td>
      <td><?php echo $number; ?></td>
    </tr>
  <?php } ?>
</table>

<form method="post" action="">
<input type="text" name="name"/>
<input type="text" name="mobile"/>
<input type="submit" name="submit"/>
</form>

＆＃13;

这里没有预定义的内容选项

＆＃13;

<?php
    session_start();
    
    // if new contact added
    if ($_SERVER["REQUEST_METHOD"] == "POST") {
        if (isset($_POST["name"]) && isset($_POST["mobile"])) {
            if (isset($_POST["name"]) && isset($_POST["mobile"])) {
                $name = $_POST["name"];
                $number = $_POST["mobile"];
                $appendArray = array(
                    $name => $number
                );

                // Run if the first time
                if (!isset($_SESSION["contact"])) {
                    $_SESSION["contact"] = $appendArray;
                } else {
                    
                    // create new array by merging the existing one and the new data.
                    $newList = array_merge($_SESSION["contacts"], $appendArray);
                    $_SESSION["contact"] = $newList;
                }
            }
        }
    }
?>

<table>
  <tr>
    <th>S.NO</th>
    <th>NAME</th>
    <th>MOBILE</th>
  </tr>
  <?php
    if (isset($_SESSION["contact"])){
    $cl = $_SESSION["contact"];
    $size = 0;
    foreach ($cl as $name => $number) {
  ?>
    <tr>
      <td><?php echo ++$size; ?></td>
      <td><?php echo $name; ?></td>
      <td><?php echo $number; ?></td>
    </tr>
    <?php }} ?>
</table>

<form method="post" action="">
<input type="text" name="name"/>
<input type="text" name="mobile"/>
<input type="submit" name="submit"/>
</form>

Answer 2

<?php
echo '<table><tr><th>ONE</th><th>TWO</th></tr>';
for($i = 0; $i < 3; $i++) {
    echo '<tr>';
    echo '<td>';
    echo $i;
    echo '</td>';
    echo '<td>';
    echo $i*2;
    echo '</td>';
    echo '</tr>';
}
echo '</table>';

它使用for循环来绘制带有值的表。您必须使用所需的会话变量替换变量，并更改for循环，使其仅循环到您希望结束的时间
