The reason why PhpStudy chose to run CodeIgniter on PhpStudy is that PhpStudy provides convenient PHP, Apache and MySQL configurations, combined with the lightweight features of CodeIgniter, can improve development efficiency. 1. Make sure PhpStudy is installed and runs normally, and start Apache and MySQL services. 2. Decompress the CodeIgniter source code to the root directory of PhpStudy's website. 3. Configure the base_url and database connection of CodeIgniter to ensure that the MySQL service has been started and the database is created. 4. Solve possible 404 errors and database connection issues, check the .htaccess file and database configuration. 5. Select the appropriate PHP version and configure the cache to optimize performance. 6. Keep PhpStudy and CodeIgniter versions updated and back up projects regularly.

Before I start explaining in detail, let's answer a key question: Why choose to run CodeIgniter on PhpStudy? As an integrated development environment (IDE), PhpStudy provides convenient PHP, Apache and MySQL configurations, making it the first choice for many developers, especially for those who want to quickly build a development environment. CodeIgniter, as a lightweight PHP framework, can greatly improve development efficiency with PhpStudy's simplicity.

Now let's dive into the key points of how to configure and run CodeIgniter source code on PhpStudy.

Running CodeIgniter on PhpStudy is not complicated, but to ensure everything runs smoothly, you need to pay attention to some critical configuration steps and possible problems. I will share some practical tips and experiences to help you avoid common pitfalls.

First, you need to make sure PhpStudy is installed and runs properly. This means that both Apache and MySQL services should be in startup state. If you are just starting to use PhpStudy, it is recommended to be familiar with its basic operations, such as how to start/stop the service, how to switch the PHP version, etc.

Next, decompress the source code of CodeIgniter to the root directory of PhpStudy's website. For example, if your PhpStudy is installed on D disk, you will usually decompress CodeIgniter to D:\phpStudy\WWW directory. After completing this step, open your browser and visit http://localhost/ and you should be able to see the CodeIgniter welcome page.

However, it is not enough to do this. You need to do some basic configuration of CodeIgniter to make sure it works correctly in PhpStudy environment. Open application/config/config.php file, find the base_url configuration item, and set it to your local address, for example:

 $config['base_url'] = 'http://localhost/';

This configuration tells CodeIgniter what the basic URL of your website is. In addition, you need to configure the database connection. Open application/config/database.php file, find the database configuration item, and set it according to the MySQL configuration in your PhpStudy. For example:

 $db['default'] = array(
    'dsn' => '',
    'hostname' => 'localhost',
    'username' => 'root',
    'password' => '',
    'database' => 'your_database_name',
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    'pconnect' => FALSE,
    'db_debug' => (ENVIRONMENT !== 'production'),
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
);

After configuring the database, you need to make sure that the MySQL service in PhpStudy has been started and that you have created the corresponding database.

During the configuration process, you may encounter some common problems, such as 404 errors or database connection failures. A common way to fix 404 errors is to check if your .htaccess file is configured correctly. CodeIgniter provides a .htaccess file by default, ensuring that it has not been renamed or deleted. If you are using Apache 2.4 and above, you may need to modify RewriteEngine On and RewriteCond rules in the .htaccess file.

Regarding the problem of failure in database connection, first check whether your database configuration is correct, including username, password, and database name. Second, make sure that the MySQL service in PhpStudy is started and that you have permission to access the database.

In terms of performance optimization, PhpStudy offers a variety of PHP version options. You can choose the appropriate PHP version according to your project requirements. Typically, newer PHP versions have improved performance and security. In addition, CodeIgniter itself also supports caching mechanism, which allows you to configure cache to improve the response speed of your application.

Finally, share some personal experiences and suggestions. When running CodeIgniter with PhpStudy, I found it very important to keep PhpStudy and CodeIgniter versions updated. New versions usually fix some known bugs and introduce new features. At the same time, it is also a good habit to back up your project regularly to prevent data loss.

Overall, running CodeIgniter on PhpStudy is an efficient and convenient option. With the right configuration and some basic debugging tips, you can quickly build a development environment and start your project development journey. Hope these experiences and suggestions help you run CodeIgniter smoothly on PhpStudy.
