create table

或者只是在没有必要时删除它：

CREATE TABLE `testphp`(
    `id` INT(11) NOT NULL AUTO_INCREMENT,
    `another_id` NUMERIC(60) DEFAULT NULL, -- Here!
    `name` VARCHAR(255),
    `email` VARCHAR(255),
    `mobile` NUMERIC(60) DEFAULT NULL,
    `image` VARCHAR(255),
    `Gender` VARCHAR(255),
    `Day` VARCHAR(255),
    `status` ENUM('0','1'),
    PRIMARY KEY (`id`) 
);

在SQL中实际上有两列名为id的列，尝试重命名一列。
