java save information php read and write memcache garbled problem_PHP tutorial
We use java to write the data and then use php to read it out. However, when we use php to read it out, we find that the problem of garbled characters in memcache occurs. Now I will introduce to you the solution to the garbled characters in memcache.
java reads php and writes memcache content
Story background: I used java to insert a digital record, but it could not be read correctly using php.
Today I discovered that if you use MemCachedClient to insert a number or a Java object, it will be garbled when called out in PHP.
The object can be understood, but simple numbers will be garbled
as
代码如下 | 复制代码 |
mcc.set("a",25); |
The output in php is garbled, and if you use telnet to query
get a
A question mark comes out.
After flipping through it, I said I wanted to change the category.
Finally, I found a problem. If you use strings instead, then java and php can be used interchangeably.
The code is as follows | Copy code | ||||
mcc.set("a","25 ″);
|
And telnet 192.168.0.1 11211 can get the correct number.
Originally, I wanted to add the value a, and thought it would be more convenient to use int, but it actually conflicted with PHP's reading of memcache. Let's do variable type conversion back and forth.
If you are also using java to write to memcache, and php to read out of memcache, using the same string storage can avoid many problems.
Class packages that are not Java will not work.
java reads php and writes memcache content
Current requirements: PHP writes the key as "my_key" and the value as "my_value" into memcache, and then uses java to connect to memcache to read the value of my_key, my_value.
The code on the PHP side is:
The code is as follows | Copy code | ||||
|
After testing, after writing in php, it can be obtained very well using php and the memcache command line.
However, when using the following java code to get it, null is obtained
The code is as follows

import com.danga.MemCached.SockIOPool; |
static{
String[] servers = { "192.168.1.20:27688"};
SockIOPool pool = SockIOPool.getInstance();
Pool.setServers(servers);
Pool.initialize();
}
public void get(String name){
System.out.println(client.get(name));
}
public static void main(String[] args) {
new CacheReader().get("my_key");
}
}

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.

The article discusses PHP, detailing its full form, main uses in web development, comparison with Python and Java, and its ease of learning for beginners.

PHP handles form data using $\_POST and $\_GET superglobals, with security ensured through validation, sanitization, and secure database interactions.

The article compares PHP and ASP.NET, focusing on their suitability for large-scale web applications, performance differences, and security features. Both are viable for large projects, but PHP is open-source and platform-independent, while ASP.NET,

PHP's case sensitivity varies: functions are insensitive, while variables and classes are sensitive. Best practices include consistent naming and using case-insensitive functions for comparisons.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
