Common.php

Returns the timezone the application has been set to display dates in. This might be different than the timezone set at the server level, as you often want to stores dates in UTC and convert them on the fly for the user.

A convenience method that provides access to the Cache object. If no parameter is provided, will return the object, otherwise, will attempt to return the cached value. Examples: cache()->save('foo', 'bar'); $foo = cache('bar');

A convenience method to clean paths for a nicer looking output. Useful for exception handling, error logging, etc.

Runs a single command. Input expected in a single string as would be used on the command line itself: > command('migrate:create SomeMigration');

More simple way of getting config instances from Factories

Simpler way to create a new Cookie instance.

Fetches the global `CookieStore` instance held by `Response`.

Returns the CSRF token name. Can be used in Views when building hidden inputs manually, or used in javascript vars when using APIs.

Returns the CSRF header name. Can be used in Views by adding it to the meta tag or used in javascript to define a header name when using APIs.

Returns the current hash value for the CSRF protection. Can be used in Views when building hidden inputs manually, or used in javascript vars for API usage.

Generates a hidden input field for use within manually generated forms.

Generates a meta tag for use within javascript calls.

Generates a nonce attribute for style tag.

Generates a nonce attribute for script tag.

Grabs a database connection and returns it to the user. This is a convenience wrapper for \Config\Database::connect() and supports the same parameters. Namely: When passing in $db, you may pass any of the following to connect: - group name - existing connection instance - array of database configuration values If $getShared === false then a new connection instance will be provided, otherwise it will all calls will return the same instance.

Allows user to retrieve values from the environment variables that have been set. Especially useful for retrieving values set from the .env file for use in config files.

Performs simple auto-escaping of data for security reasons. Might consider making this more complex at a later date. If $data is a string, then it simply escapes and returns it. If $data is an array, then it loops over it, escaping each 'value' of the key/value pairs. If not UTF-8, we convert strings from this encoding pre-escaping and back to this encoding post-escaping.

Used to force a page to be accessed in via HTTPS. Uses a standard redirect, plus will set the HSTS header for modern browsers that support, which gives best protection against man-in-the-middle attacks. Defaults to 1 year.

Function usable Executes a function_exists() check, and if the Suhosin PHP extension is loaded - checks whether the function that is checked might be disabled in there as well. This is useful as function_exists() will return FALSE for functions disabled via the *disable_functions* php.ini setting, but not for *suhosin.executor.func.blacklist* and suhosin.executor.disable_eval*. These settings will just terminate script execution if a disabled function is executed. The above described behavior turned out to be a bug in Suhosin, but even though a fix was committed for 0.9.34 on 2012-02-12, that version is yet to be released. This function will therefore be just temporary, but would probably be kept for a few years. FALSE otherwise.

Loads a helper file into memory. Supports namespaced helpers, both in and out of the 'Helpers' directory of a namespaced directory. Will load ALL helpers of the matching name, in the following order: 1. app/Helpers 2. {namespace}/Helpers 3. system/Helpers

Check if PHP was invoked from the command line.

Tests for file writability is_writable() returns TRUE on Windows servers when you really can't write to the file, based on the read-only attribute. is_writable() is also unreliable on Unix servers if safe_mode is on.

Detect if platform is running in Windows.

A convenience method to translate a string or array of them and format the result with the intl extension's MessageFormatter.

A convenience/compatibility method for logging events through the Log system. Allowed log levels are: - emergency - alert - critical - error - warning - notice - info - debug

More simple way of getting model instances from Factories

Provides access to "old input" that was set in the session during a redirect()->withInput().

Convenience method that works with the current global $request and $router instances to redirect using named/reverse-routed routes to determine the URL to go to. If more control is needed, you must use $response->redirect explicitly.

Generates the solidus character (`/`) depending on the HTML5 compatibility flag in `Config\DocTypes`

Remove Invisible Characters This prevents sandwiching null characters between ascii characters, like Java\0script.

Returns the shared Request.

Returns the shared Response.

Given a route name or controller/method string and any params, will attempt to build the relative URL to the matching route. NOTE: This requires the controller/method to have a route defined in the routes Config file. The last parameter allows you to set the locale.

A convenience method for accessing the session instance, or an item that has been set in the session. Examples: session()->set('foo', 'bar'); $foo = session('bar');

Allows cleaner access to the Services Config file. Always returns a SHARED instance of the class, so calling the function multiple times should always return the same instance. These are equal: - $timer = service('timer') - $timer = \CodeIgniter\Config\Services::timer();

Always returns a new instance of the class.

Fetch a config file item with slash appended (if not empty) the item doesn't exist

Stringify attributes for use in HTML tags. Helper function used to convert a string, array, or object of attributes to a string.

A convenience method for working with the timer. If no parameter is passed, it will return the timer instance. If callable is passed, it measures time of callable and returns its return value if any. Otherwise will start or stop the timer intelligently.

Grabs the current RendererInterface-compatible class and tells it to render the specified view. Simply provides a convenience method that can be used in Controllers, libraries, and routed closures. NOTE: Does not provide any escaping of the data, so that must all be handled manually by the developer.

View cells are used within views to insert HTML chunks that are managed by other classes.

Get the class "basename" of the given object / class.

Returns all traits used by a class, its parent classes and trait of their traits.

Returns all traits used by a trait and its traits.
