我在使用PHP向数据库中插入数据时发现一个问题，当插入一个字段类型为varchar的值时，无论插入的内容是多少个0，数据库都默认认为是一个0。请教大神。why？这种情况该怎么处理。

上sql语句
表结果截图

INSERT INTO user (PhoneNumber,Password) VALUES (12312312312,000000)

INSERT INTO user (PhoneNumber,Password) VALUES ('12312312312','000000')

请加上单引号，谢谢

你把0 加上引号试试。

字符类型，sql语句里要给加上单引号

字符串需要用引号包围，否则会转为数字，00000转数字就是0，所以数据库中保存的就是0了。

varchar为字符类型
当你insert数据的时候，字符串变量需要加上引号。
