将整个表格和按钮包裹在一个表单中:

Wrap the whole table and button in a form:

<form action="" method="post">
...
...
</form>

在你的 while 循环中，在删除单元格中添加一个复选框:

Inside your while loop, add a checkbox to the delete cell:

// concatenate or echo as required
<input type="checkbox" name="delete[]" value="<?php echo (int)$rows['id']; ?>" />

确保您的按钮属于 submit 类型:

Make sure your button is of type submit:

<input type="submit" value="Delete Selected" />

在 PHP 方面:

if(isset($_POST['delete']) && is_array($_POST['delete']) && count($_POST['delete']) > 0){
    foreach($_POST['delete'] as $deleteId){
        // run query to delete $deleteId
    }
}

这是可行的，因为 PHP 将名称为 delete[] 的复选框解析为原生数组

This works because PHP parses the checkboxs with the names delete[] into a native array
