Since the creation of PHP language in 1994, it has been magically sought after as the preferred language for website design. The release of PHP4.0 in 2000 undoubtedly injected fresh blood into it, and it is also respected for its open source mind. Beginners in learning programming languages are nothing more than examples of learning grammar and basic application. During this period, I will record the process of PHP bit by bit, first, to summarize myself, and second, to solve the problems of learners who encounter the same problems in the future.
Notes and records mainly appear in the form of problems, and will not explore the basics of language bit by bit like in a book class. It is mainly to foresee problems in the basic stage of PHP learning and record them one by one, and record the process of never understanding them. OK ReallyPHPLanguage is the beginning。
1): What kind of development environment and development tools does PHP require?
It is necessary to understand the version issue of PHP language, but I don’t think it’s much relevant. Baidu/google can find these developed version issues. If you want to do things well, you must choose a sharp tool! The first time I was configuring the development environment. The development environment I first came into contact with was Windows, but this time I was willing to conduct subsequent learning on Linux. Now I will display the deployment of both development environments once.
2): What are the steps for installing windows? What aspects should be paid attention to?
First of all, Windows. Generally, in order to facilitate the implementation of the installation tool suite, I will use WampServer development here. Wamp is the Windows Apache Mysql PHP integrated installation environment, that is, the server software of apache, php and mysql under Windows. There is no need to think too much about installing and deploying servers, databases, etc. You can proceed directly from the next step. However, please pay attention to the following points during the installation process:
1. The path where the WampServer program is located cannot contain Chinese characters and spaces.
2. MySQL default username: root, password is empty
3. MySQL database file storage directory: wamp\bin\mysql\mysql5.5.8\data
4. Website root directory [HTML,PHP]wamp\www
5. Please use http://127.0.0.1/ to access this machine (if port 80 is not occupied)
6. Non-default port, URL is http://127.0.0.1:port/
If an IIS server is installed, port 80 is occupied by default. You need to change the wamp service Internet port number: C:\wamp\bin\apache\Apache2.2.17\conf folder with file Listen node, modify port number 80, or what you need. After modification, restart all services and run them.
Development tools: PHP development tools: Zend Studio, PHPedit, EditPlus 2, easyeclipse, DW, etc. can all be completed. It is easier to use the inherited development tool Zend.
3): Is it also an installation package deployment environment in the Linux environment? Is there a graphical management interface?
However, on Linux, we can still develop PHP. The development environment I chose here is LAMP (linux+Apache+Mysql+PHP), and the Ubuntu distribution version is used as an example to install the development environment. The Apache official website card can be downloaded offline installation package or installed online. It is more convenient to choose online installation here. First use the Ubuntu system and enter the window command (Ctrl+Alt+t)
Apache installation
As a powerful web program, Apache is naturally the first choice for building a web server. Okay, let’s install Apache. Enter the following command in the terminal:
sudo apt-get install apache2
After the installation is complete, the next step is to start Apache
sudo /etc//apache2 restart
Enter http://localhost or http://127.0.0.1 in the browser. If you see "It works!", it means that Apache has been installed successfully. Apache's default installation will create a directory called www under /var. This is the web directory. All web files that need to be accessed through the browser must be placed in this directory.
Installation of PHP
Installing software in Ubuntu is a very simple thing. You only need one command. Execute the following command in the terminal:
sudo apt-get install libapache2-mod-php5 php5
After installation, we need to restart Apache and let it load the PHP module:
sudo /etc//apache2 restart
Next, we will create a new PHP file in the web directory to test whether PHP can run normally. The command:
sudo gedit /var/www/
Then enter:
<?php bloginfo(); ?> (Note: When using bloginfo, change to phpinfo, because of the server's limitations, the phpinfo function cannot be used)
Then save the file and enter http://127.0.0.1/ in the browser. If a page displays PHP running parameters appears, it means that PHP is running normally.
However, if the page is not displayed, you are prompted to download the file, which means that Apaceh does not load the PHP module correctly. The solution at this time is to add the following line of command to the /etc /apache2/ or /etc/apache2/mods-enabled/ file:
AddType application/x-httpd-php .php .phtml .php3
After adding the above command, restarting Apaceh through the following command will solve the problem:
sudo /etc//apache2 stop
sudo /etc//apache2 restart
There is a situation where this expected page does not appear later. It is possible that the folder www does not obtain appropriate access rights. You can change the permissions of the www folder through sudo chmod +x ./www. (You should understand this permission management in Linux)
MySQL installation
sudo apt-get install mysql-server
At the end of the installation, it will ask for the root password to enter. Note that the root password here is not the root password of Ubuntu, it is the root password you want to set for MySQL. Of course, if you are happy, it is OK to set it the same. Because it is mainly used for local testing, MySQL is installed here. If it is really used as a server, you may also need to refer to other settings. As for these settings, I will write them down after the subsequent use.
Okay, the development environment installation is over, wait to write a program that complies with the rules!
