今天测试一个功能,需要往数据库中插入一些原始数据,PM给了一个txt文件,如何快速的将这个txt文件的内容拆分为所要的数组,然后再插入到数据库中?
serial_number.txt的示例内容:
serial_number.txt:
DM00001A11 0116, SN00002A11 0116, AB00003A11 0116, PV00004A11 0116, OC00005A11 0116, IX00006A11 0116,
创建数据表:
create table serial_number( id int primary key auto_increment not null, serial_number varchar(50) not null )ENGINE=InnoDB DEFAULT CHARSET=utf8;
php代码如下:
$conn = mysql_connect('127.0.0.1','root','') or die("Invalid query: " . mysql_error()); mysql_select_db('test', $conn) or die("Invalid query: " . mysql_error()); $content = file_get_contents("serial_number.txt"); $c//explode()函数以","为标识符进行拆分 foreach ($contents as $k => $v)//遍历循环 { $id = $k; $serial_number = $v; mysql_query("insert into serial_number (`id`,`serial_number`) VALUES('$id','$serial_number')"); }
备注:方法有很多种,我这里是在拆分txt文件为数组后,然后遍历循环得到的数组,每循环一次,往数据库中插入一次。
再给大家分享一个支持大文件导入的

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.
