When we [extend Expression Language](http://symfony.com/doc/current/components/expression_language/extending.html), we often need to add PHP functions whose code is repetitive and redundant at the compiler/evaluator level. This PR proposes a new way more generic which allows to add a PHP function.
currently:
```php
$el = new ExpressionLanguage();
$compiler = function ($str) {
return sprintf('strtoupper(%s)', $str);
};
$evaluator = function ($arguments, $str) {
return strtoupper($str);
};
$el->addFunction(new ExpressionFunction('strtoupper', $compiler, $evaluator));
$el->evaluate('strtoupper("hello")'); // return "HELLO"
```
with this PR:
```php
$el->addFunction(ExpressionFunction::fromPhp('strtoupper'));
$el->evaluate('strtoupper("hello")'); // return "HELLO"
```
It includes PHP namespaced function:
```php
$el->addFunction(ExpressionFunction::fromPhp('My\strtoupper', 'my_strtoupper'));
$el->evaluate('my_strtoupper("hello")'); // return "HELLO"
```
