Winserver2008 is full of troubles. When configuring wamp 2.2e on winserver, it fails to run and crashApp error is reported.
I have been working on it for a long time but still can’t solve it. Can anyone give me some advice? Later I downloaded wamp 2a and it can be installed, but its PHP version is
5.2, I need to upgrade the PHP version later, at least to 5.3!
The specific installation failure and PHP version upgrade issues will be written in the next article. Here I will write about the configuration issues of apache and server.
First: resolve the domain name to the external IP of the server. As for how to resolve it. . Check it out yourself, I won’t say more!
Secondly: Find #Include conf/extra/httpd-vhosts.conf and remove the # sign in front of it
As a result, APACHE cannot be started after restarting it. Why?
I deleted all the contents in httpd-vhosts.conf and restarted without any problem. I suspect something in the httpd-vhosts.conf file is wrong.
I really don’t know the details, so I will bring the 2 I brought with me
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot "c:/Apache2/docs/dummy-host.example.com"
ServerName dummy-host .example.com
ServerAlias www.dummy-host.example.com
ErrorLog "logs/dummy-host.example.com-error.log"
CustomLog "logs/dummy-host.example.com -access.log" common
Delete all these things and check them using
CustomLog "logs/dummy-host2.example.com-access.log" common
Attention
The following paragraph is used to configure the domain name and path
ServerAdmin webmaster@dummy-host2.example.com
DocumentRoot "E:/www/yl/"
ServerName www.1y.com.cn
ErrorLog "logs/dummy-host2.example. com-error.log"
CustomLog "logs/dummy-host2.example.com-access.log" common
The following paragraph is to grant permissions to the website folder. If you do not add this sentence, a 400 error will occur when accessing
AllowOverride None
Order allow,deny
Allow from all
Of course, don’t forget to change the host file to point to
127.0.0.1 Your domain name
Then access the configured domain name on the server to access the website.
So how to access the external network?
If the external domain name is resolved, it can be accessed. Of course, when I start accessing, it prompts that the connection cannot be made!
I thought it must be a problem with the external IP address, so I turned off the firewall that comes with win2008, and then accessed it from the outside,
It must be that the firewall has restricted the entry rules for port 80.
Then open the firewall-"Advanced rules-"New rule-"Give a name, and then select the port,
Next step -> Enter 80, then the next step, and then the name and so on. The creation is completed. Open the firewall,
Access from the outside again, OK!
Okay, the technical level of this article is approximately 0, but sometimes it can be reused, so MARK it.

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.

Fibers was introduced in PHP8.1, improving concurrent processing capabilities. 1) Fibers is a lightweight concurrency model similar to coroutines. 2) They allow developers to manually control the execution flow of tasks and are suitable for handling I/O-intensive tasks. 3) Using Fibers can write more efficient and responsive code.

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

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),
