Scrutinizer analyzes your composer.json/composer.lock file if available to
determine the classes, and functions that are defined by your dependencies.


It seems like the listed class was neither found in your dependencies, nor was it
found in the analyzed files in your repository. If you are using some other form
of dependency management, you might want to disable this analysis.

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.
