Download and install the CodeIgniter framework, codeigniter framework

CodeIgniter is a set of application development frameworks and toolkits for PHP website developers. When I first learned Php, I searched a lot of PHP frameworks online and finally chose CodeIgniter. The following introduces to coders how to download and install the CodeIgniter framework.

Installation environment: php5 mysql6.5 iis7

My computer is used for office work and writing documents. It is a win7 system. I don’t want to change the system, so I installed the iis7 that comes with win7.

php download is the latest php-5.3.28-nts-Win32-VC9-x86

mysql is also downloaded the latest.

Download address:

php：http://windows.php.net/downloads/releases/

mysql:http://dev.mysql.com/downloads/mysql/

CodeIgniter:http://codeigniter.org.cn/

Of course, I am configuring it in a windows environment, so I need to download the relevant version of the software under windows. If it is Linux, etc., I need to download the software supported by the system.

Okay, without further ado, let’s start the installation and explore step by step after installation. First of all, I am a newbie, so please correct me if I am wrong in many things. I mainly work in non-IT now and I don’t update often. I occasionally take a break and read a book.

Step one: Download codeigniter, which is a compressed package. After decompression, it looks like this:

There are mainly these 3 files. The application folder is the application folder, which mainly contains MVC-related M-model folders,

V-view folder, C-controller folder, and some configuration files, which will be discussed later.

The system file is the system folder and the core file of CI (CodeIgniter).

user_guide is the offline user help document for easy query. But they are all in English. If your English is not good, you should go to Baidu and download a Chinese document. My study mainly relies on help documents. The help documentation is a good thing. First of all, I chose this framework because its detailed help documentation makes it easy to learn.

The second step: is also a more critical step. Place this folder in the root directory of the website. A lot of online information only talks about the root directory. Newbies like me don't even know the root directory.

Now I will tell you about the root directory. I installed iis, so the root directory refers to the installation directory of iis. For other web servers, the root directory refers to the installation directory of the web server. As shown below: Open iis, right-click, browse, and the root directory will be opened; (I don’t know how to use screenshot software, so I will use a big picture for now, and try to learn how to take screenshots next time)

Step 3: This is the crucial step, it is destined to fail.

Copy the downloaded file to this so-called root directory; I changed the name of this folder to php, mainly for simplicity, because the access address needs to be configured. It is convenient to enter the address.

Step 4: The most important thing is configuration

Open the application/config/config.php file. Note that .php files can be opened with various editors such as Notepad and Notpad, which is very convenient. Just configure and save.

Mainly configure these two places: Mark 1 configures the URL of the website you want to visit. What I configured is http://localhost/php, localhost refers to local. It can also be written as http://127.0.0.1/php. If you have a server, then you need to write the domain name of your server. /php is the folder of CodeIgniter that I just copied and downloaded. I changed the folder name to php for easy access. php is shorter than CodeIgniter.

Mark 2 index.php is configured after downloading. If it is not configured, you can configure it as index.php, which means that if you enter http://127.0.0.1/php, the index.php file will be automatically opened.

The fifth step is to configure the server and database. I use mysql

Open the file application/config/database.php

Configure your server’s username, password, database name, etc. As shown below:

This picture does not need to be explained, everyone can understand it, even beginners will know what to fill in when they read English.

Okay, that’s it, it’s over.

Enter http://127.0.0.1/php in the browser to see the welcome interface of index.php.

welcome............
