For compatibility and reusability of your code, PSR1 recommends that a file should introduce either new symbols (like classes, functions, etc.) or have side-effects (like outputting something, or including other files), but not both at the same time. The first symbol is defined on line 27 and the first side effect is on line 15.
The PSR-1: Basic Coding Standard recommends that a file should either introduce
new symbols, that is classes, functions, constants or similar, or have side effects.
Side effects are anything that executes logic, like for example printing output,
changing ini settings or writing to a file.
The idea behind this recommendation is that merely auto-loading a class should not change the state
of an application. It also promotes a cleaner style of programming and makes your code
less prone to errors, because the logic is not spread out all over the place.

PSR-1.
It seems like you do not handle an error condition here. This can introduce security issues, and is generally not recommended.
If you suppress an error, we recommend checking for the error condition explicitly:
// For example instead of@mkdir($dir);// Better useif(@mkdir($dir)===false){thrownew\RuntimeException('The directory '.$dir.' could not be created.');}
put uses the super-global variable $_SESSION which is generally not recommended.
Instead of super-globals, we recommend to explicitly inject the dependencies
of your class. This makes your code less dependent on global state and it
becomes generally more testable:
// BadclassRouter{publicfunctiongenerate($path){return$_SERVER['HOST'].$path;}}// BetterclassRouter{private$host;publicfunction__construct($host){$this->host=$host;}publicfunctiongenerate($path){return$this->host.$path;}}classController{publicfunctionmyAction(Request$request){// Instead of$page=isset($_GET['page'])?intval($_GET['page']):1;// Better (assuming you use the Symfony2 request)$page=$request->query->get('page',1);}}
get uses the super-global variable $_SESSION which is generally not recommended.
