"insert.php" 文件连接数据库,并通过 $_POST 变量从表单取回值。然后,mysql_query() 函数执行 INSERT INTO 语句,一条新的记录会添加到数据库表中。 下面是 "insert.php" 页面的代码: <?php$con=mysql_connect("localhost","peter","abc123");if(!$con) {die('Could not connect: ' .mysql_error())...
格式:int mysql_db_query(string database , string sqlquery , int link_identifier); 在此函数中必须指定数据库名database和SQL语句sqlquery,如失败则返回False。 例子: <?php $connect = mysql_connect($hostname , $user , $pwd); $query = mysql_db_query($dbname , $sql , $connect); if($quer...

1. PHP 连接 MySQL 1.面向对象 在面向对象的方式中,mysqli被封装成一个类,它的构造方法如下: AI检测代码解析 __construct ([ string $host [, string $username [, string $passwd [, string $dbname [, int $port [, string $socket ]]] ) 1. ...
在插入数据行时候,Mysql将会使用VALUES的值填入对应字段名,例如星空幻颖将会被插入到name字段。因为提供了字段名,所以字段的顺序也不一定需要按照数据库字段排序。 比方我们可以改写上面的SQL语句: INSERT INTO `test`.`br_user` (`user_id`, `password`, `email`, `name`) VALUES (NULL, '123456', '123@...
