The call to the method ImpressaoFiscalController::rodape() seems un-needed as the method has no side-effects.
                                                                                                                                                    

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
PHP Analyzer performs a side-effects analysis of your code. A side-effect is
basically anything that might be visible after the scope of the method is left.


Let’s take a look at an example:


class User
{
    private $email;

    public function getEmail()
    {
        return $this->email;
    }

    public function setEmail($email)
    {
        $this->email = $email;
    }
}





If we look at the getEmail() method, we can see that it has no side-effect.
Whether you call this method or not, no future calls to other methods are affected
by this. As such code as the following is useless:


$user = new User();
$user->getEmail(); // This line could safely be removed as it has no effect.





On the hand, if we look at the setEmail(), this method _has_ side-effects.
In the following case, we could not remove the method call:


$user = new User();
$user->setEmail('email@domain'); // This line has a side-effect (it changes an
                                 // instance variable).

The method gerar_arquivo() contains an exit expression.
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
An exit expression should only be used in rare cases. For example, if you
write a short command line script.


In most cases however, using an exit expression makes the code untestable
and often causes incompatibilities with other libraries. Thus, unless you are
absolutely sure it is required here, we recommend to refactor your code to
avoid its usage.

Using logical operators such as or instead of || is generally not recommended.
                                                                                                                                                    

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
PHP has two types of connecting operators (logical operators, and boolean operators):


 
Logical Operators
Boolean Operator

AND - meaning
and
&&

OR - meaning
or
||

The difference between these is the order in which they are executed. In most cases,
you would want to use a boolean operator like &&, or ||.


Let’s take a look at a few examples:


// Logical operators have lower precedence:
$f = false or true;

// is executed like this:
($f = false) or true;


// Boolean operators have higher precedence:
$f = false || true;

// is executed like this:
$f = (false || true);







Logical Operators are used for Control-Flow


One case where you explicitly want to use logical operators is for control-flow
such as this:


$x === 5
    or die('$x must be 5.');

// Instead of
if ($x !== 5) {
    die('$x must be 5.');
}





Since die introduces problems of its own, f.e. it makes our code hardly
testable, and prevents any kind of more sophisticated error handling; you probably
do not want to use this in real-world code. Unfortunately, logical operators
cannot be combined with throw at this point:


// The following is currently a parse error.
$x === 5
    or throw new RuntimeException('$x must be 5.');





These limitations lead to logical operators rarely being of use in current
PHP code.

The property corpoTxt does not exist on object<ImpressaoFiscalController>. Since you implemented __set, maybe consider adding a @property annotation.
                                                                                                                                                    

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
Since your code implements the magic setter _set, this function will be called for any write access on an
undefined variable. You can add the @property annotation to your class or interface to document
the existence of this variable.


<?php

/**
 * @property int $x
 * @property int $y
 * @property string $text
 */
class MyLabel
{
    private $properties;

    private $allowedProperties = array('x', 'y', 'text');

    public function __get($name)
    {
        if (isset($properties[$name]) && in_array($name, $this->allowedProperties)) {
            return $properties[$name];
        } else {
            return null;
        }
    }

    public function __set($name, $value)
    {
        if (in_array($name, $this->allowedProperties)) {
            $properties[$name] = $value;
        } else {
            throw new \LogicException("Property $name is not defined.");
        }
    }

}





Since the property has write access only, you can use the @property-write annotation instead.


Of course, you may also just have mistyped another name, in which case you should fix the error.


See also the PhpDoc documentation for
@property.

exibir uses the super-global variable $_GET 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:


// Bad
class Router
{
    public function generate($path)
    {
        return $_SERVER['HOST'].$path;
    }
}

// Better
class Router
{
    private $host;

    public function __construct($host)
    {
        $this->host = $host;
    }

    public function generate($path)
    {
        return $this->host.$path;
    }
}

class Controller
{
    public function myAction(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);
    }
}

The method exibir() contains an exit expression.
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
An exit expression should only be used in rare cases. For example, if you
write a short command line script.


In most cases however, using an exit expression makes the code untestable
and often causes incompatibilities with other libraries. Thus, unless you are
absolutely sure it is required here, we recommend to refactor your code to
avoid its usage.
