Laravel 4.2 URI based configuration - php

I'm working on a project which has multiple URL's, and each URL need a custom configuration. It does not have to be in it's own configuration file, but would be a nice to have (for a clear overview of project structure).
At the moment I have the following in my custom configuration file, which works - but is IMO not the best place to put this.
$domain = $_SERVER['HTTP_HOST'];
switch($domain)
{
case 'domain':
$var = 'foo';
break;
case 'otherdomain':
$var = 'bar';
break;
}
I've tried adding the same code to filters, in App::before function (but instead of $var =, I do:)
Config::set('var','foo')
Unfortunately, this does not give me the desired effect, when I do it like this - I cannot access Config::get('var') in my configuration file to make the switch between the different variables I need per URL.
I'm pretty sure there should be a better way to handle this than my "I'll add it to config file". Can anybody point me into the right direction?

I think you should use environments for this. Just create directories under app/config like:
config
-- domain
-- otherdomain
And place a file in them. Let's say app.php. In there you return an array of config values:
return array(
'foo' => 'bar'
);
And finally, in bootstrap/start.php, change the detectEnvironment call to this:
$env = $app->detectEnvironment(function()
{
return $_SERVER['HTTP_HOST'];
});

Update .env value using PHP

I know some of your might think that this will lead to security issue. 🔐 🐞
But ...
I only want to update only 2 specific flags, because sometimes, I want to see the reports, and sometimes, I don't. If I have a way to update those flags -- I can just hook up a route to toggle that functionality - via Apple iPhone Shortcut whenever I want to see reports via EMAIL or SMS.
I've tried
created a route
Route::get('/env/{flag}/{value}','GeneralController#envUpdate');
called it
http://localhost/env/MAIL_REPORT/false
that will trigger this function
public function setEnv($key, $val)
{
$path = base_path('.env');
if (file_exists($path)) {
file_put_contents($path, str_replace(
$key . '=' . env($key), $key . '=' . $val, file_get_contents($path)
));
}
}
public function envUpdate($flag,$value)
{
//dd($flag,$value);
$allow_flags = ["MAIL_REPORT", "SMS_REPORT"];
if (in_array($flag, $allow_flags))
{
setEnv((string)$flag, (string)$value);
return env(env((string)$flag));
}
}
I kept getting true because in my .env does not seem to be updated
MAIL_REPORT=true
I suppose to have MAIL_REPORT=false
Note : I already ran : sudo chmod 777 .env
How would one go about and debug this further?
If you need to change the environment variables I would suggest to just change your .env file and re-cache your config (if in production). Your current implementation might be pretty sensitive for security issues.
If you do want to change your env variables programmatically at run time you can always use the config() helper method.
config(['mailing. reporting' => false]);
This is also documented in the docs.
Edit
So I think you're implementation of the env variables might be a little incorrect. The environment variables itself SHOULD NOT change at run time in your applications. The only place where the env() function should be called is in the config files (found in the config directory). So what you want is to create a new key in your config/mailing.php config file.
'reporting' => env('MAIL_REPORT', false),
Now whenever you need to set this variable to true you can either change the .env file or use the first given example (config(['mailing. reporting' => false]);).
Read more about it in the docs.

How can I check if a configuration parameter exists?

I use Symfony 2.3.x for an application I currently develop.
I have this structure in my app/config/ folder:
environment/dev/file.yml
environment/test/file.yml
environment/myenv/file.yml
and so on
In each of these files, I have something like:
parameters:
myvalue: 2000
In my Controller, I do this:
$v = $this->container->getParameter('myvalue');
var_dump($v);
The above code will dump the value int 2000.
So everything works great.
But I want to handle the situation where myvalue is not defined. If I simply delete this variable from the YAML files, I get an HTTP 500 error with a huge stack-trace.
I want to do something like:
if (variable_exists ('myvalue')) {
$x = $this->container->getParameter('myvalue');
else {
$x = SOME_DEFAULT_VALUE;
}
useVariable($x);
Does Symfony have some sort of function that does what the variable_exists() function mentioned above does ?
I couldn't find anything in the docs.
Thank you in advance.
You could try calling $container->hasParameter('myvalue');. See here for more details.

Yii console with different configs

In the web application we use same code and modules with different configs like:
in index.php file app will decide, wchin config to turn:
switch($_SERVER['HTTP_HOST']){
default:
$yii=$webRoot.'/framework/yiilite.php';
$config = $webRoot.'/protected/config/main.php';
break;
case 'someurl.com':
...
break;
...
}
But, how can I do it with console application?
The reason in that I use different databases ant etc.
is it possible to do something like this:
$ ./protected/yiic --application=myappname [all defined commands as default]
in the code a
--application
will set with which console config to work
more explanation
my answer to #Joe Miller
But the problem is, how choose theme?
I did in the files foloowings:
in protectes/yiic
$__appId = null;
for( $__i=1,$__max=count($argv); $__i<$__max; ++$__i ) {
if ( strpos($argv[$__i],'--appid',0) === 0 ) {
$__appId = substr($argv[$__i], 8);
unset($argv[$__i]);
}
}
require_once(dirname(__FILE__).'/yiic.php');
and in protected/yiic.php
$__appIdsList = array(
'my_site_1',
'my_site_2',
'my_site_3',
'my_site_4',
);
$yiic=dirname(__FILE__).'/../framework/yiic.php';
$config=dirname(__FILE__).'/config/console_'.$__appId.'.php';
require_once($yiic);
and it works and it catchs that config file what I need
./protected/yiic --appid=my_site_1
bu when I`m trying to do migrate
./protected/yiic --appid=my_site_1 migrate
the app cant recognize comman and gives me migrates help list
And final conslusion (I solved it)
I`d like to add transperent console command without affecting it to other execution of builtin console commands and custom console commands.
Another requirement is, solve this issue on a low-level approach, without inheritance or overloading other classes or methods.
So, my solution is:
in protected/yiic
#!/usr/bin/env php
<?php
$__appId = null;
for( $__i=1,$__max=count($argv); $__i<$__max; ++$__i ) {
if ( strpos($argv[$__i],'--appid',0) === 0 ) {
$__appId = substr($argv[$__i], 8);
unset($argv[$__i]);
unset($_SERVER['argv'][$__i]);
$argv = $_SERVER['argv'] = array_values($argv);
}
}
require_once(dirname(__FILE__).'/yiic.php');
and in /protected/yiic.php
<?php
// change the following paths if necessary
$__appIdsList = array(
'app_1',
'app_2',
);
$yiic=dirname(__FILE__).'/../framework/yiic.php';
$config=dirname(__FILE__).'/config/console_'.$__appId.'.php';
if ( !is_file($config) ) {
die("Error: There is no or wrong parametr appid. Please set parametr or correct. Example -appid={application_name}\n\tThe list of available appid:\n\t\t - ".implode("\n\t\t - ", $__appIdsList));
}
require_once($yiic);
and now it is possible to set param "appid" in any place of command line, like
./protected/yiic migrate --appid=app_1
and it acts only in that app what we need
PS: in any case, thanks #Joe Miller
Copy yiic.php for example to cron.php and modify the config file in the cron.php
then use as if it were yiic, for example:
cd ~/protected;php ~/protected/cron.php app command --param=value >> ~/runtime/crontab.log
If I've understood what you're trying to do correctly, I think you might need something like this. I've referred to this article http://www.yiiframework.com/doc/guide/1.1/en/topics.console#creating-commands. I've not tried this, so I'm just interpreting the article.
Create a base command class, from which you will extend all the other commands. The base class run() method selects the config file to load.
In protected>commands you need a file migrate.php. This must contain the class MigrateCommand, and must extend CConsoleCommand. You can then override the run() method of this class to allow parameters to be passed to the method. e.g.
In protected>commands>baseCommand.php
class MyBaseCommand extends CConsoleCommand{
public function run($args){
//Code here to select the config file to load
//$args are any arguments you have passed in the command line
}
}
In protected>commands>migrate.php
class Migrate extends MyBaseCommand{
public function run($args){
parent::run($args);
//Do your own stuff here
}
}
you should then be able to call the command as;
./protected/yiic migrate --appid=my_site_1
Note that the name of the command appears first, I'm not sure if this is important, but it's what the guide says! I hope I've understood your question this time!
I think, I founded more confortable solution!
It`s more easy, and solved all my requirements.
in the file
protected/yiic.php
I write:
...
$yiic=dirname(__FILE__).'/../lib/framework/yiic.php';
if ( strpos(__FILE__,{first/place}) !== false ) {
$config=dirname(__FILE__).'/config/first_config.php';
} elseif ( strpos(__FILE__,{second/place}) !== false ) {
$config=dirname(__FILE__).'/config/second_plase.php';
} else {
// by default
$config=dirname(__FILE__).'/config/console.php';
}
require_once($yiic);
...
where {first/place},{second/place} - a part of the project`s path. For example:
Your first project is placed in:
/var/www/aproject/first_one
and the second one on the
/var/www/aproject/second_one
than you checks will be:
// for first porject
strpos(__FILE__,'aproject/first_one') !== false
and etc.

Defining Application Constants in Codeigniter

I want to know a clean way of defining Application Constants in Codeigniter. I don't want to change any native file of codeigniter. Hence I don't want to define it in application/config/constants.php as when I need to migrate to newer version of code-igniter I will not be able to copy the native files of codeigniter directly.
I created a file application/config/my_constants.php and defined my constants there. 'define('APP_VERSION', '1.0.0');'
I loaded it using $this->load->config('my_constants');
But I am getting a error
Your application/config/dv_constants.php file does not appear to contain a valid configuration array.
Please suggest me a clean way of defining application level constants in code-igniter.
Not using application/config/constants.php is nonsense! That is the only place you should be putting your constants. Don't change the files in system if you are worried about upgrading.
just a complete answer. (None of the answers show how to use the constants that were declared)
The process is simple:
Defining a constant. Open config/constants.php and add the following line:
define('SITE_CREATOR', 'John Doe')
use this constant in another file using:
$myVar = 'This site was created by '.SITE_CREATOR.' Check out my GitHub Profile'
Instead of using define(), your my_constants.php file should look something like this:
$config['app_version'] = '1.0.0';
Be careful with naming the array key though, you don't want to conflict with anything.
If you need to use define(), I would suggest doing it in the main index.php file, though you will still need to use APP_VERSION to get the value.
config file (system/application/config/config.php) to set configuration related variables.
Or use
constant file (system/application/config/constants.php) to store site preference constants.
=======================
DEFINE WHAT YOU WANT
=======================
$config['index_page'] = 'home';
$config['BASEPATH'] = 'PATH TO YOUR HOST';
Please refer this:

Define variable in to constants & add value on array
$ORDER_STATUS = array('0'=>'In Progress','1'=>'On Hold','2'
=>'Awaiting Review','3'=>'Completed','4'
=>'Refund Requested','5'=>'Refunded');
You can accomplish your goal by adding constants to your own config file, such as my_config.php.
You would save this file in the application/config folder, like this:
application/config/my_config.php.
It is very common to have a separate config file for each application you write, so this would be easy to maintain and be understood by other CI programmers.
You can instruct CI to autoload this file or you can load it manually, as needed. See the CI manual on "Config class".
Let me suggest that you use composer.json to autoload your own Constants.php file, like this:

PHP - Application config file stored as - ini,php,sql,cached,php class,JSON,php array?

I am trying to decide on the best way to store my applications configuration settings. There are so many options.
The majority of applications I have seen have used a simple require and a PHP file that contains variables. There seem to be far more advanced techniques out there.
What have you used?
What is most efficient?
What is most secure?
We use a file called Local.php which is excluded from the SCM system. It contains several constants or global variables. For example:
// Local.php
class Setting
{
const URL = 'http://www.foo.com';
const DB_User = 'websmith';
}
And it can be referred to anywhere simply by:
Setting::URL
If you need the settings to be writable at runtime, I suggest you use public static variables instead.
The best thing you can do is the simplest thing that could possibly work (php variables) and wrap it up in a class. That way you can change the implementation later without changing any client code. Create an interface that the configuration class implements and make the client code use the interface methods. If you later decide to store configuration in a database or JSON or whatever, you can simply swap out the existing implementation with a new one. Make sure your configuration class is testable and write unit tests.
Try to use php-arrays config files using technique described here: http://www.dasprids.de/blog/2009/05/08/writing-powerful-and-easy-config-files-with-php-arrays
This method allows you to write app configuration in this way:
app.config.php
<?php
return array(
'appname' => 'My Application Name',
'database' => array(
'type' => 'mysql',
'host' => 'localhost',
'user' => 'root',
'pass' => 'none',
'db' => 'mydb',
),
);
This method is secure, cache-able by opcode cachers (APC, XCACHE).
How about:
; <?php die('Direct access not allowed ;') ?>
; The above is for security, do not remove
[database]
name = testing
host = localhost
user = root
pass =
[soap]
enableCache = 1
cacheTtl = 30
Save as config.php (or something like that, must have php extention), and then just load it with:
parse_ini_file('config.php', true);
And you could use
array_merge_recursive(parse_ini_file('config-default.php', true), parse_ini_file('config.php', true))
to merge a default config file with a more specific config file.
The point here is that you can use the very readable ini format, but still be able to have your config file in a public directory.
When you open the file with your browser, php will parse it first and give you the result, which will just be "; Direct access not allowed ;". When you parse the file directly as an ini file, the php die statement will be commented out according to the ini syntax (;) so it will not have any effect then.
I find Zend_Config to be a good solution. You can load the configuration from a simple array, from an INI style file, or from an XML document. Whichever you choose, the configuration object is the same, so you can switch storage formats freely. Zend_Config objects can also be merged, depending on your application this may be useful (a server config, then a per site/installation config).
As with most (or all) things in the Zend Framework, you can easily use Zend_Config by itself.
Considering efficiency, I'd say the fastest method would be to use an array, since that requires less (in this case no) string parsing. However, a INI/XML format may be easier for some to maintain. Of course some caching would give you the best of both worlds.
Also, using INI files with Zend_Config allow you to define sections of configurations that inherit from each other. The most common use is a 'development' section that inherits from the 'production' section, then redefines the DB/debugging settings.
As for security, keeping the config file out of the web root is the first step. Making it read only and limiting access could make it more secure; however, depending on your hosting/server configuration you may be limited in what can be done there.
Just an example of how to implement a central XML/Xpath configuration.
class Config {
private static $_singleton;
private $xml;
static function getInstance() {
if(is_null (self::$_singleton) ) {
self::$_singleton = new self;
}
return self::$_singleton;
}
function open($xml_file) {
$this->xml = simplexml_load_file($xml_file);
return $this;
}
public function getConfig($path=null) {
if (!is_object($this->xml)) {
return false;
}
if (!$path) {
return $this->xml;
}
$xml = $this->xml->xpath($path);
if (is_array($xml)) {
if (count($xml) == 1) {
return (string)$xml[0];
}
if (count($xml) == 0) {
return false;
}
}
return $xml;
}
}
Example call
Config::getInstance()
->open('settings.xml')
->getConfig('/settings/module/section/item');
In my view good solution would be ini files.
I don't prefer config file using arrays/variables for storing settings; here is why:
What if a user accidently re-named your setting variable?
What if a variable with similar name is defined elsewhere too by the user?
Variables in config file may be overwritten some where deep in the script or even included files.
and possibly more problems....
I like to use ini file for setting of my php apps. Here is why:
It is section based
It is easier
You can set values by friendly names
You don't have to worry about variables being overwritten because there are no ones.
No conflict of variables of course.
It allows more flexibility in specifying the types of values.
Note: You need to use parse_ini_file function to read ini files.
It is best to do any core configuration in PHP itself, but if you are using a database and don't mind the extra overhead - you may find some flexibility in storing some settings in the database with a single extra query (assuming you organize it properly).
Either way, storing this data in JSON, INI, XL, etc is just another unneeded abstraction that is done way too much nowadays on the web. Your best bet is pure PHP, unless you like the flexibility of some settings being in the database.
The only reason I can think of to not use php vars as others are suggesting is if you need to switch between configurations in a controlled manner, so there data/behavior consistency during the switch. For example, if you're switching databases, then the system could write locked until the switch-over occurs (to prevent ghost-writes, but dirty reads are still possible).
If things like this are a concern, then you could write a special admin page in your app(pref local access only for security) that locks the system temporarily, then reads and deploys all your changes before unlocking.
If you're running a high traffic site where consistency matters, this is something you'll want to consider. If you can deploy during off hours when there is little/no traffic, then php vars or other standard text formats will be fine.
I like the idea of having "namespaces" or some kind of tree
so you can have:
db.default.user
or
db.readonly.user
and so on.
now regarding code what I did was an interface for the config readers: so you can have a memory reader, array reader, db reader, etc.
and a config class that uses those readers and allow you have a config from any kind of source
