				+| -------------------------------------------------------------------
			
 
				+| EXPLANATION OF VARIABLES
			
 
				+| -------------------------------------------------------------------
			
 
				+|
			
 
				+|	['dsn']      The full DSN string describe a connection to the database.
			
 
				+|	['hostname'] The hostname of your database server.
			
 
				+|	['username'] The username used to connect to the database
			
 
				+|	['password'] The password used to connect to the database
			
 
				+|	['database'] The name of the database you want to connect to
			
 
				+|	['dbdriver'] The database driver. e.g.: mysqli.
			
 
				+|			Currently supported:
			
 
				+|				 cubrid, ibase, mssql, mysql, mysqli, oci8,
			
 
				+|				 odbc, pdo, postgre, sqlite, sqlite3, sqlsrv
			
 
				+|	['dbprefix'] You can add an optional prefix, which will be added
			
 
				+|				 to the table name when using the  Query Builder class
			
 
				+|	['pconnect'] TRUE/FALSE - Whether to use a persistent connection
			
 
				+|	['db_debug'] TRUE/FALSE - Whether database errors should be displayed.
			
 
				+|	['cache_on'] TRUE/FALSE - Enables/disables query caching
			
 
				+|	['cachedir'] The path to the folder where cache files should be stored
			
 
				+|	['char_set'] The character set used in communicating with the database
			
 
				+|	['dbcollat'] The character collation used in communicating with the database
			
 
				+|				 NOTE: For MySQL and MySQLi databases, this setting is only used
			
 
				+| 				 as a backup if your server is running PHP < 5.2.3 or MySQL < 5.0.7
			
 
				+|				 (and in table creation queries made with DB Forge).
			
 
				+| 				 There is an incompatibility in PHP with mysql_real_escape_string() which
			
 
				+| 				 can make your site vulnerable to SQL injection if you are using a
			
 
				+| 				 multi-byte character set and are running versions lower than these.
			
 
				+| 				 Sites using Latin-1 or UTF-8 database character set and collation are unaffected.
			
 
				+|	['swap_pre'] A default table prefix that should be swapped with the dbprefix
			
 
				+|	['encrypt']  Whether or not to use an encrypted connection.
			
 
				+|
			
 
				+|			'mysql' (deprecated), 'sqlsrv' and 'pdo/sqlsrv' drivers accept TRUE/FALSE
			
 
				+|			'mysqli' and 'pdo/mysql' drivers accept an array with the following options:
			
 
				+|
			
 
				+|				'ssl_key'    - Path to the private key file
			
 
				+|				'ssl_cert'   - Path to the public key certificate file
			
 
				+|				'ssl_ca'     - Path to the certificate authority file
			
 
				+|				'ssl_capath' - Path to a directory containing trusted CA certificates in PEM format
			
 
				+|				'ssl_cipher' - List of *allowed* ciphers to be used for the encryption, separated by colons (':')
			
 
				+|				'ssl_verify' - TRUE/FALSE; Whether verify the server certificate or not
			
 
				+|
			
 
				+|	['compress'] Whether or not to use client compression (MySQL only)
			
 
				+|	['stricton'] TRUE/FALSE - forces 'Strict Mode' connections
			
 
				+|							- good for ensuring strict SQL while developing
			
 
				+|	['ssl_options']	Used to set various SSL options that can be used when making SSL connections.
			
 
				+|	['failover'] array - A array with 0 or more data for connections if the main should fail.
			
 
				+|	['save_queries'] TRUE/FALSE - Whether to "save" all executed queries.
			
 
				+| 				NOTE: Disabling this will also effectively disable both
			
 
				+| 				$this->db->last_query() and profiling of DB queries.
			
 
				+| 				When you run a query, with this setting set to TRUE (default),
			
 
				+| 				CodeIgniter will store the SQL statement for debugging purposes.
			
 
				+| 				However, this may cause high memory usage, especially if you run
			
 
				+| 				a lot of SQL queries ... disable this to avoid that problem.
			
 
				+|
			
 
				+| The $active_group variable lets you choose which connection group to
			
 
				+| make active.  By default there is only one group (the 'default' group).

				+| URI ROUTING
			
 
				+| -------------------------------------------------------------------------
			
 
				+| This file lets you re-map URI requests to specific controller functions.
			
 
				+|
			
 
				+| Typically there is a one-to-one relationship between a URL string
			
 
				+| and its corresponding controller class/method. The segments in a
			
 
				+| URL normally follow this pattern:
			
 
				+|
			
 
				+|	example.com/class/method/id/
			
 
				+|
			
 
				+| In some instances, however, you may want to remap this relationship
			
 
				+| so that a different class/function is called than the one
			
 
				+| corresponding to the URL.
			
 
				+|
			
 
				+| Please see the user guide for complete details:
			
 
				+|
			
 
				+|	https://codeigniter.com/user_guide/general/routing.html
			
 
				+|
			
 
				+| -------------------------------------------------------------------------
			
 
				+| RESERVED ROUTES
			
 
				+| -------------------------------------------------------------------------
			
 
				+|
			
 
				+| There are three reserved routes:
			
 
				+|
			
 
				+|	$route['default_controller'] = 'welcome';
			
 
				+|
			
 
				+| This route indicates which controller class should be loaded if the
			
 
				+| URI contains no data. In the above example, the "welcome" class
			
 
				+| would be loaded.
			
 
				+|
			
 
				+|	$route['404_override'] = 'errors/page_missing';
			
 
				+|
			
 
				+| This route will tell the Router which controller/method to use if those
			
 
				+| provided in the URL cannot be matched to a valid route.
			
 
				+|
			
 
				+|	$route['translate_uri_dashes'] = FALSE;
			
 
				+|
			
 
				+| This is not exactly a route, but allows you to automatically route
			
 
				+| controller and method names that contain dashes. '-' isn't a valid
			
 
				+| class or method name character, so it requires translation.
			
 
				+| When you set this option to TRUE, it will replace ALL dashes in the
			
 
				+| controller and method URI segments.
			
 
				+|
			
 
				+| Examples:	my-controller/index	-> my_controller/index
			
 
				+|		my-controller/my-method	-> my_controller/my_method

				+# Contributing to CodeIgniter
			
 
				+
			
 
				+CodeIgniter is a community driven project and accepts contributions of code and documentation from the community. These contributions are made in the form of Issues or [Pull Requests](http://help.github.com/send-pull-requests/) on the [CodeIgniter repository](https://github.com/bcit-ci/CodeIgniter) on GitHub.
			
 
				+
			
 
				+Issues are a quick way to point out a bug. If you find a bug or documentation error in CodeIgniter then please check a few things first:
			
 
				+
			
 
				+1. There is not already an open Issue
			
 
				+2. The issue has already been fixed (check the develop branch, or look for closed Issues)
			
 
				+3. Is it something really obvious that you can fix yourself?
			
 
				+
			
 
				+Reporting issues is helpful but an even better approach is to send a Pull Request, which is done by "Forking" the main repository and committing to your own copy. This will require you to use the version control system called Git.
			
 
				+
			
 
				+## Guidelines
			
 
				+
			
 
				+Before we look into how, here are the guidelines. If your Pull Requests fail
			
 
				+to pass these guidelines it will be declined and you will need to re-submit
			
 
				+when you’ve made the changes. This might sound a bit tough, but it is required
			
 
				+for us to maintain quality of the code-base.
			
 
				+
			
 
				+### PHP Style
			
 
				+
			
 
				+All code must meet the [Style Guide](https://codeigniter.com/user_guide/general/styleguide.html), which is
			
 
				+essentially the [Allman indent style](https://en.wikipedia.org/wiki/Indent_style#Allman_style), underscores and readable operators. This makes certain that all code is the same format as the existing code and means it will be as readable as possible.
			
 
				+
			
 
				+### Documentation
			
 
				+
			
 
				+If you change anything that requires a change to documentation then you will need to add it. New classes, methods, parameters, changing default values, etc are all things that will require a change to documentation. The change-log must also be updated for every change. Also PHPDoc blocks must be maintained.
			
 
				+
			
 
				+### Compatibility
			
 
				+
			
 
				+CodeIgniter recommends PHP 5.4 or newer to be used, but it should be
			
 
				+compatible with PHP 5.2.4 so all code supplied must stick to this
			
 
				+requirement. If PHP 5.3 (and above) functions or features are used then
			
 
				+there must be a fallback for PHP 5.2.4.
			
 
				+
			
 
				+### Branching
			
 
				+
			
 
				+CodeIgniter uses the [Git-Flow](http://nvie.com/posts/a-successful-git-branching-model/) branching model which requires all pull requests to be sent to the "develop" branch. This is
			
 
				+where the next planned version will be developed. The "master" branch will always contain the latest stable version and is kept clean so a "hotfix" (e.g: an emergency security patch) can be applied to master to create a new version, without worrying about other features holding it up. For this reason all commits need to be made to "develop" and any sent to "master" will be closed automatically. If you have multiple changes to submit, please place all changes into their own branch on your fork.
			
 
				+
			
 
				+One thing at a time: A pull request should only contain one change. That does not mean only one commit, but one change - however many commits it took. The reason for this is that if you change X and Y but send a pull request for both at the same time, we might really want X but disagree with Y, meaning we cannot merge the request. Using the Git-Flow branching model you can create new branches for both of these features and send two requests.
			
 
				+
			
 
				+### Signing
			
 
				+
			
 
				+You must sign your work, certifying that you either wrote the work or otherwise have the right to pass it on to an open source project. git makes this trivial as you merely have to use `--signoff` on your commits to your CodeIgniter fork.
			
 
				+
			
 
				+`git commit --signoff`
			
 
				+
			
 
				+or simply
			
 
				+
			
 
				+`git commit -s`
			
 
				+
			
 
				+This will sign your commits with the information setup in your git config, e.g.
			
 
				+
			
 
				+`Signed-off-by: John Q Public <john.public@example.com>`
			
 
				+
			
 
				+If you are using [Tower](http://www.git-tower.com/) there is a "Sign-Off" checkbox in the commit window. You could even alias git commit to use the `-s` flag so you don’t have to think about it.
			
 
				+
			
 
				+By signing your work in this manner, you certify to a "Developer's Certificate of Origin". The current version of this certificate is in the `DCO.txt` file in the root of this repository.
			
 
				+
			
 
				+## How-to Guide
			
 
				+
			
 
				+There are two ways to make changes, the easy way and the hard way. Either way you will need to [create a GitHub account](https://github.com/signup/free).
			
 
				+
			
 
				+Easy way GitHub allows in-line editing of files for making simple typo changes and quick-fixes. This is not the best way as you are unable to test the code works. If you do this you could be introducing syntax errors, etc, but for a Git-phobic user this is good for a quick-fix.
			
 
				+
			
 
				+Hard way The best way to contribute is to "clone" your fork of CodeIgniter to your development area. That sounds like some jargon, but "forking" on GitHub means "making a copy of that repo to your account" and "cloning" means "copying that code to your environment so you can work on it".
			
 
				+
			
 
				+1. [Set up Git](https://help.github.com/en/articles/set-up-git) (Windows, Mac & Linux)
			
 
				+2. Go to the [CodeIgniter repo](https://github.com/bcit-ci/CodeIgniter)
			
 
				+3. [Fork it](https://help.github.com/en/articles/fork-a-repo)
			
 
				+4. [Clone](https://help.github.com/en/articles/fetching-a-remote#clone) your forked CodeIgniter repo: git@github.com:<your-name>/CodeIgniter.git.
			
 
				+5. Checkout the "develop" branch. At this point you are ready to start making changes.
			
 
				+6. Fix existing bugs on the Issue tracker after taking a look to see nobody else is working on them.
			
 
				+7. [Commit](https://help.github.com/en/articles/adding-a-file-to-a-repository-using-the-command-line) the files
			
 
				+8. [Push](https://help.github.com/en/articles/pushing-to-a-remote) your develop branch to your fork
			
 
				+9. [Send a pull request](https://help.github.com/en/articles/creating-a-pull-request)
			
 
				+
			
 
				+The Reactor Engineers will now be alerted about the change and at least one of the team will respond. If your change fails to meet the guidelines it will be bounced, or feedback will be provided to help you improve it.
			
 
				+
			
 
				+Once the Reactor Engineer handling your pull request is happy with it they will merge it into develop and your patch will be part of the next release.
			
 
				+
			
 
				+### Keeping your fork up-to-date
			
 
				+
			
 
				+Unlike systems like Subversion, Git can have multiple remotes. A remote is the name for a URL of a Git repository. By default your fork will have a remote named "origin" which points to your fork, but you can add another remote named "codeigniter" which points to `git://github.com/bcit-ci/CodeIgniter.git`. This is a read-only remote but you can pull from this develop branch to update your own.
			
 
				+
			
 
				+If you are using command-line you can do the following:
			
 
				+
			
 
				+1. `git remote add codeigniter git://github.com/bcit-ci/CodeIgniter.git`
			
 
				+2. `git pull codeigniter develop`
			
 
				+3. `git push origin develop`
			
 
				+
			
 
				+Now your fork is up to date. This should be done regularly, or before you send a pull request at least.

				+What is CodeIgniter
			
 
				+###################
			
 
				+
			
 
				+CodeIgniter is an Application Development Framework - a toolkit - for people
			
 
				+who build web sites using PHP. Its goal is to enable you to develop projects
			
 
				+much faster than you could if you were writing code from scratch, by providing
			
 
				+a rich set of libraries for commonly needed tasks, as well as a simple
			
 
				+interface and logical structure to access these libraries. CodeIgniter lets
			
 
				+you creatively focus on your project by minimizing the amount of code needed
			
 
				+for a given task.
			
 
				+
			
 
				+*******************
			
 
				+Release Information
			
 
				+*******************
			
 
				+
			
 
				+This repo contains in-development code for future releases. To download the
			
 
				+latest stable release please visit the `CodeIgniter Downloads
			
 
				+<https://codeigniter.com/download>`_ page.
			
 
				+
			
 
				+**************************
			
 
				+Changelog and New Features
			
 
				+**************************
			
 
				+
			
 
				+You can find a list of all changes for each release in the `user
			
 
				+guide change log <https://github.com/bcit-ci/CodeIgniter/blob/develop/user_guide_src/source/changelog.rst>`_.
			
 
				+
			
 
				+*******************
			
 
				+Server Requirements
			
 
				+*******************
			
 
				+
			
 
				+PHP version 5.6 or newer is recommended.
			
 
				+
			
 
				+It should work on 5.3.7 as well, but we strongly advise you NOT to run
			
 
				+such old versions of PHP, because of potential security and performance
			
 
				+issues, as well as missing features.
			
 
				+
