Php 从会话数组中删除值

如何使用表中的删除链接从会话数组中删除值

//归档

< ?php
$_SESSION['cart']['prices'][] = "1000";
$_SESSION['cart']['services'][] = "game 1";
$_SESSION['cart']['prices'][] = "2000";
$_SESSION['cart']['services'][] = "game 2";
$_SESSION['cart']['prices'][] = "3000";
$_SESSION['cart']['services'][] = "game 3";
$_SESSION['cart']['prices'][] = "4000";
$_SESSION['cart']['services'][] = "game 4";
?>

<？php
$\u会话['cart']['prices'][]=“1000”；
$\会话['cart']['services'][]=“游戏1”；
$\会话['cart']['prices'][]=“2000”；
$\会话['cart']['services'][]=“游戏2”；
$\会话['cart']['prices'][]=“3000”；
$\会话['cart']['services'][]=“游戏3”；
$\会话['cart']['prices'][]=“4000”；
$\会话['cart']['services'][]=“游戏4”；
?>

//在文件B中

< table border="1">
< thead>
< th style="width: 450px; text-align:center;">Services< /th>
< th style="width: 450px; text-align:center;">Price< /th>
< th style="width: 450px; text-align:center;">Delete item< /th>
< /thead>
< tbody>
< ?php
foreach ($_SESSION['cart']['services'] as $key => $service) {
    echo "< tr>< td>".$service."< /td>< td style='text-align:center;'>".$_SESSION['cart']['prices'][$key]."< /td>< td>ckick to remove< /td>< /tr>";
}
?>
< /tbody>
< /table>

服务
价格
删除项目

<？php
foreach（$\会话['cart']['services']作为$key=>$service）{
echo“”；
}
?>


”$service。”
>“$\u会话['cart']['prices'][$key]。”
单击以删除“

使用

unset（）

重置会话值：

unset($_SESSION['cart']['services']);

---

尝试使用“unset（）”？例如

unset（$\u会话['cart']['services']）更好
取消设置（$_会话['cart']['services'][$indexToRemove]）但我想删除特定的服务和价格。怎么可能呢？“只需使用
$\u SESSION['cart']['services'][$index]=null或
取消设置（$_会话['cart']['services']）
