我想将1.txt中的内容12345写入到a.txt中指定的位置既下图:abcde和abcde的中间
求思路,最好能详细一些,谢谢了。
回复讨论(解决方案)
$s1 = file_get_contents('1.txt');$s2 = file_get_contents('a.txt');file_put_contents('a.txt', substr($s2, 0, 5) . $s1 . substr($s2, 5));
不好意思,我描述的不够清楚。
是这样子的,见下图
我要在 |内容前|的后面,和 |内容后|的前面分别写入1.txt的内容,请问有没好点的方法,因为有很多这样的文件,内容并不是一模一样的。
你说的很清楚了,但是你没有说清楚识别标志(被你涂鸦掉了)
a.txt
我是要插入的内容
b.txt
|标题前|我是标题|标题后||内容前|我是内容我是内容我是内容|内容后|
执行插入的php
$insert = file_get_contents('a.txt');$content = file_get_contents('b.txt');$content = str_replace('|内容前|', '|内容前|'.$insert, $content);$content = str_replace('|内容后|', $insert.'|内容后|', $content);file_put_contents('b.txt', $content, true);
执行完后 b.txt 更新为
|标题前|我是标题|标题后||内容前|我是要插入的内容我是内容我是内容我是内容我是要插入的内容|内容后|
理解错了,改成这样应该可以。
a.txt, b.txt不变,用上一贴的。
php修改为
$insert = file_get_contents('a.txt');$content = file_get_contents('b.txt');$content = str_replace('|内容前|', $insert, $content);$content = str_replace('|内容后|', $insert, $content);file_put_contents('b.txt', $content, true);
执行后b.txt
|标题前|我是标题|标题后|
我是要插入的内容我是内容我是内容我是内容 我是要插入的内容

没看到楼主最后这句话。。
原来我发的第一贴就是对的。。。
谢谢傲雪,和版主。感激。。

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

The main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.

Implementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.

SessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.

Managing sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.
