如何在使用PHP和MySQL的复选框中使用布尔值

问题描述 投票：0回答：1

所以我试图弄清楚如何使用复选框设置布尔值。

编辑：我需要将布尔值保存到数据库中，如果在编辑联系人或添加新联系人时选中，则为true；如果未选中，则为false。

我曾经在PHP和MySQL中使用过字符串和整数，但是似乎无法弄清楚布尔值（我对PHP还是很陌生）。

同样，我知道这样设置字符串，但是对于布尔值我该怎么办？还是仅仅是字符串？我可以将其验证为字符串还是整数？

mysqli_stmt_bind_param($stmt, 'sssssssss', $gos_bname, $gos_pname, $gos_email, $gos_url, $gos_phone, $gos_address, $gos_city, $gos_province, $gos_desc);

我知道很多，但是这是我到目前为止所拥有的一切。

您可以使用数据类型ENUM和值'1'，'0'吗？这可能有助于将1分配为true，将0分配为false。
