i am using laravel 5.5 and want to create constants and use in my controller and view . i use a code but it's not working. Please help me
i create a file app/config/constant.php and call the constant
echo config('constant.myVariable');
Create a file in config.
# file named config/foo.php
<?php
return [
'bar' => 'baz',
];
Then you can output the value of bar in this way:
Config::get('foo.bar');
May be this is helpful to you.
add line on top
use App\config;
then try to call
echo config('constant.myVariable');
Step 1 - Create constants.php in config/ folder(In which all config files are present. auth, database etc.).
Step 2 - Define constants in key => value pair in that file,
return[
'userAuthKey' => '21991325b1e2a4f',
'userName' => 'dummy'
];
Step 3 - Close php artisan serve'
Step 4 - Run command, php artisan config:cache
Step 5 - Run command. php artisan serve
Step 6 - Get value of spacific variable,
$auth = config('constants.userAuthKey');
Steps to create constant file for Laravel 5.5
1) Create constants.php file in the config folder.
The constants.php file will look like -
<?php
return [
'name' => 'Stack Overflow',
];
2) Access it anywhere in the following way -
config('constants.name')
The above-mentioned call will contain your constant value.

The current Behavior:
I wanted to add an extra custom type and followed:
https://docs.typo3.org/p/georgringer/news/master/en-us/DeveloperManual/ExtendNews/AddCustomType/Index.html
Exactly at it was explained there...
The expected behavior/output:
This gives me in the Backend an extra custom type myCustomNewsType.
However, when I call the Frontend, I get:
Core: Exception handler (WEB): Uncaught TYPO3 Exception:
#1476045117: Could not find class definition for name "Galileocr\CustomPackage\Domain\Model\MyCustomNewsType".
This could be caused by a mis-spelling of the class name in the class definition. | TYPO3\CMS\Extbase\Persistence\Generic\Exception\InvalidClassException thrown in file /usr/home/galileo98/public_html/typo3_src-9.5.11/typo3/sysext/extbase/Classes/Persistence/Generic/Mapper/DataMapFactory.php in line 131.
Environment
TYPO3 version(s): [9.5.0]
news version: [e.g. 7.0.5]
Composer (Composer Mode): [ no]
OS: [e.g. OSX 10.13.4]
I have no idea why this occurs, is this example not complete?
Did you configure the class autoloading after adding the new class? If this is a try-out, you should add an autoloading line to the composer.json in the root of your project.
{
"autoload": {
"psr-4": {
"Galileocr\\CustomPackage\\": "typo3conf/ext/custom_package/Classes/"
}
}
}
After that you should regenerate the autoload files by issuing a composer dumpautoload from the directory in which you just edited the composer.json.
I did not make the TYPO3 install with composer (no composer file in the root of my project), did it the "classical" way.
However, you definitely pointed me in the right direction: I opened the file typo3conf/autoload/autoload_psr4.php:
<?php
// autoload_classmap.php #generated by TYPO3
$typo3InstallDir = \TYPO3\CMS\Core\Core\Environment::getPublicPath() . '/';
return array(
'BK2K\\BootstrapPackage\\' => array($typo3InstallDir . 'typo3conf/ext/bootstrap_package/Classes'),
'GeorgRinger\\News\\' => array($typo3InstallDir . 'typo3conf/ext/news/Classes'),
);
So no reference to my custom class...
Therefore, I went to Admin tools->Maintenance->Rebuild PHP Autoload Information and refreshed the autoload info. After that, the same file looks like this:
<?php
// autoload_classmap.php #generated by TYPO3
$typo3InstallDir = \TYPO3\CMS\Core\Core\Environment::getPublicPath() . '/';
return array(
'BK2K\\BootstrapPackage\\' => array($typo3InstallDir . 'typo3conf/ext/bootstrap_package/Classes'),
'Galileocr\\BciePackage\\' => array($typo3InstallDir . 'typo3conf/ext/bcie_package/Classes'),
'GeorgRinger\\News\\' => array($typo3InstallDir . 'typo3conf/ext/news/Classes'),
);
The the problem was fixed!!!
Thanks and regards!

Ok, in laravel 4, if I want to add my own custom class, eg : library\myFunction.php then I do the following steps :
add "myFunctions.php" into app/library/myFunctiosn.php
at app/start/global.php , within ClassLoader::addDirectories(array( , I add app_path().'/library',
And to call it within my blade view, I add the following codes
<?php
$FmyFunctions1 = new myFunctions;
$is_ok1=($FmyFunctions1->is_ok());
?>
The contents of app/library/myFunctions.php is :
<?php namespace App\library {
class myFunctions {
public function is_ok() {
return 'myFunction is OK';
}
}
}
?>
And it works.
But how to do so in Laravel 5 ???
PS : I read What are the best practices and best places for laravel 4 helpers or basic functions?
And tried to add "app/library/", to the autoload array and run composer dum-autoload , but it keeps give me error :
FatalErrorException in xxxx line xx: Class 'myFunctions' not found
I'm also already trying to use :
composer update
composer dump-autoload
php artisan dump
php artisan clear-compiled
php artisan dump-autoload
php artisan optimize
php artisan route:clear
php artisan route:scan
php artisan route:list
But still doesn't work...
This should help you.
FYI:
Basically, you could create another directory within app, and then namespace your files in there as appropriate:
app/CustomStuff/CustomDirectory/SomeClass.php.
Then, within your SomeClass.php, make sure you namespace it:
<?php
namespace App\CustomStuff\CustomDirectory;
class Someclass {}
Now, you can access this class using the namespace within your classes:
use App\CustomStuff\CustomDirectory\SomeClass;
After some trial and error, I found the answer.
There is no need to modify Composer. Just modify the Blade into:
<?php
$FmyFunctions1 = new \App\library\myFunctions;
$is_ok = ($FmyFunctions1->is_ok());
?>
I am trying to create controller using the command line in laravel but when i SSH to my server and try to run the laravel CLI command php artisan controller:make AboutController
or even any other command like : php artisan list
I always get this message :
{
"error":
{
"type":"ErrorException",
"message":"Missing argument 2 for Illuminate\\Routing\\Router::controller(), called in \/home1\/jokira\/public_html\/laravel\/bootstrap\/compiled.php on line 3155 and defined","file":"\/home1\/jokira\/public_html\/laravel\/bootstrap\/compiled.php","line":4379
}
}
What am i doing wrong ?
Maybe you add some wrong routes to app/routes.php just like what I did.
I add some temp route like this:
//user routes
Route::get('/login');
Route::post('/login');
Route::get('/reg');
Route::post('/reg');
And I got the same errors as you .
After I deleted this lines , all works fine now.
Wish can help you .
You need to specify the path of the route for your controller.
This is wrong example:
Route::controller('AuthController');
And this is the correct one:
Route::controller('/auth', 'AuthController');
i am using doctrine 2 on zendframework 2. i have configured both correcly and they are both working.
i however wish to use doctrine's command line tool to generate entities etc.
i have followed doctrine's instructions and created a cli-config.php page in the root of my application:
http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/configuration.html
i am however lost on two issues;
the configuration requires a bootstrap php page; however, zendframework 2 does not use a bootstrap page; so what would the equivalent be?
Secondly, it requires us to obtain an entity mangager; would the method below be the correct way to get the entity manager:
public function getEntityManager()
{
if (null === $this->em) {
$this->em = $this->getServiceLocator()->get('doctrine.entitymanager.orm_default');
}
return $this->em;
}
below is how the cli-config.php page should look;
// cli-config.php
require_once 'my_bootstrap.php';
// Any way to access the EntityManager from your application
$em = GetMyEntityManager();
$helperSet = new \Symfony\Component\Console\Helper\HelperSet(array(
'db' => new \Doctrine\DBAL\Tools\Console\Helper\ConnectionHelper($em->getConnection()),
'em' => new \Doctrine\ORM\Tools\Console\Helper\EntityManagerHelper($em)
));
i would really appreciate any help or advice on this matter.
warm regards

the matter has been resolved:!!
it did not work because i was using a cygdrive command line. however, when i switched to git bash it worked perfectly. with git bash i have to use the command:
C: > cd project-directory
project-dir > vendor\bin\doctrine-module orm:validate-schema
If you have started your project using the Zend Skeleton Application you do have a composer.json file. You just need to include the DoctrineORMModule (instructions here)
Then, using the CMD just type
C: > cd project-directory
project-dir > vendor\bin\doctrine-module orm:validate-schema
There you go.
Once you have set up doctrine2 and zf2, you should be able to simply run all CLI commands.
php public/index.php orm:generate-entities
Using the parameters as described in the official documentation.
Note: DoctrineModule and DoctrineORMModule need to be enabled within your application.config.php
You need to install the doctrine/doctrine-orm-module with your Composer dependency manager. To do that, cd to your web site's top-level directory and type the following command:
php composer.phar require doctrine/doctrine-orm-module *
After executing this command, the DoctrineModule and DoctrineOrmModule will be installed into your vendor folder, and Doctrine commands will become available.
For more information about DoctrineOrmModule, see this:
https://github.com/doctrine/DoctrineORMModule
I have been trying to make it work for sometime now, but I can't. I am working on a Windows 7 64bits, I have the Memcached Server running as Service, I have the php_memcached.dll extension in the PHP 5.3.8 and when I call it on the app in Codeigniter I do it the right way (I Think).
$this->load->driver('cache', array('adapter' => 'memcached', 'backup' => 'file'));
var_dump($this->cache->memcached->is_supported());
die();
but it throws a false so I don't know what I am doing wrong. When I call it like this:
$this->load->driver('cache', array('adapter' => 'memcached', 'backup' => 'file'));
$data = $this->cache->memcached->get('data_' . $idData);
I get this PHP error:
Fatal error: Call to a member function get() on a non-object in E:\workspace\example\system\libraries\Cache\drivers\Cache_memcached.php on line 50
Thanks for the help :-)
The CI driver is looking for the Apache Module, but in WIN we use mostly the PHP-Class Memcache.
Try to change Line 165 in /system/libraries/Cache/drivers/Cache_memcached.php
$this->_memcached = new Memcached();
For me it works after changing from Memcached to Memcache.
$this->_memcached = new Memcache();
I know this is old, but I just came across the same issue.
On Windows, you should be using "Memcache" rather than "Memcached". To do this, follow the instructions on this page:
http://www.leonardaustin.com/technical/how-to-install-memcached-on-xampp-on-windows-7
Then, to get it working in CI, you'll need to make two small changes to \system\libraries\Cache\drivers\Cache_memcached.php:
In function is_supported(), replace:
if ( !extension_loaded('memcached'))
With:
if ( !extension_loaded('memcached') && !extension_loaded('memcache'))
And in function _setup_memcached(), replace:
$this->memcached = new Memcached();
With:
if(class_exists("Memcached"))
$this->_memcached = new Memcached();
else
$this->_memcached = new Memcache();
