Our type inference engine in quite powerful, but sometimes the code does not
provide enough clues to go by. In these cases we request you to add a @return
annotation as described here.

$distributor is not used, you could remove the assignment.
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
This check looks for variable assignements that are either overwritten by other
assignments or where the variable is not used subsequently.


$myVar = 'Value';
$higher = false;

if (rand(1, 6) > 3) {
    $higher = true;
} else {
    $higher = false;
}





Both the $myVar assignment in line 1 and the $higher assignment in line 2
are dead. The first because $myVar is never used and the second because
$higher is always overwritten for every possible time line.

The variable $distributorID does not seem to be defined for all execution paths leading up to this point.
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
If you define a variable conditionally, it can happen that it is not defined
for all execution paths.


Let’s take a look at an example:


function myFunction($a) {
    switch ($a) {
        case 'foo':
            $x = 1;
            break;

        case 'bar':
            $x = 2;
            break;
    }

    // $x is potentially undefined here.
    echo $x;
}





In the above example, the variable $x is defined if you pass “foo” or “bar”
as argument for $a. However, since the switch statement has no default
case statement, if you pass any other value, the variable $x would be undefined.




Available Fixes


  1. Check for existence of the variable explicitly:
    

    function myFunction($a) {
    switch ($a) {
        case 'foo':
            $x = 1;
            break;

        case 'bar':
            $x = 2;
            break;
    }

    if (isset($x)) { // Make sure it's always set.
        echo $x;
    }
}

    

    

    2. 

  2. Define a default value for the variable:
    

    function myFunction($a) {
    $x = ''; // Set a default which gets overridden for certain paths.
    switch ($a) {
        case 'foo':
            $x = 1;
            break;

        case 'bar':
            $x = 2;
            break;
    }

    echo $x;
}

    

    

    3. 

  3. Add a value for the missing path:
    

    function myFunction($a) {
    switch ($a) {
        case 'foo':
            $x = 1;
            break;

        case 'bar':
            $x = 2;
            break;

        // We add support for the missing case.
        default:
            $x = '';
            break;
    }

    echo $x;
}
