一、设置 PHP 开发环境 构建一个可工作的开发环境可能是令人生畏的,尤其是对于绝对的初学者来说。为了跟进本书中的项目,您需要访问 Apache、PHP 和 MySQL 的有效安装,最好是在您的本地机器上。出于速度和安全性的考虑,总是希望在本地进行测试。这样做既保护了你正在进行的工作不受开放互联网的影响,又减少了上...
$column2 = utf8_decode($column2); mysqli_query($connection, “INSERT INTO `table_name` (`column1`, `column2`) VALUES (‘$column1’, ‘$column2’)”); 注意:`table_name`为表名,`column1`和`column2`为列名,$connection为数据库连接对象名。 PHP与数据库连接时出现中文乱码问题是比较常见的...
In this scenario, we create an array of element with no index specified. In such case, PHP automatically creates an integer index for the elements. The integer index starts at 0, incrementing by one for the next elements. In the following example, we created an array with elements, but n...
