CODING GUIDELINE
-------------------

Fork the project, create a feature branch, and send us a pull request.
Preferably on a distinct branch.

To ensure a consistent code base, you should make sure the code follows
the [PSR-12: Extended Coding Style](https://www.php-fig.org/psr/psr-12/). You can also
run [php-cs-fixer](https://github.com/FriendsOfPHP/PHP-CS-Fixer) with the
configuration file that can be found in the project root directory.

PHPFASTCACHE's specialties 
-------------------
As of the V7 your contributions MUST comply the following standards:

### PHP CORE FUNCTIONS
- To improve Opcode efficiency, you MUST prefix core function by a '\\'
  - E.g: `$var = \str_replace('value', '', $var);`
  
### PHP CORE CONSTANTS
- To improve Opcode efficiency, you MUST prefix core constants by a '\\'
  - E.g: `$dateFormat = \DATE_ISO8601`

### PHP CORE CLASSES
- Do not import non-namespaced classes, use an absolute path instead:  
  - E.g: `$date = new \DateTime();`

### CODE STYLE
- Unneeded/inconsistent `else` statements have to be shortened.
  - E.g: 
 ```php 
 <?php
function setAcme($acme)
{
    if ($acme instanceof Acme) {
        $this->acme = $acme;
        return $this;
    } else {
        throw new phpFastCacheInvalidArgumentException('Invalid acme instance');
    }
}
 ```
  - This example can be safely replaced by this one:
```php 
 <?php
function setAcme($acme)
{
    if ($acme instanceof Acme) {
        $this->acme = $acme;
        return $this;
    } 

    throw new phpFastCacheInvalidArgumentException('Invalid acme instance');
}
 ```
