It seems like you do not handle an error condition for header_remove(). This can introduce security issues, and is generally not recommended.
                                                                                                                                       (

 If this is a false-positive, you can also ignore this issue in your code via the ignore-unhandled   annotation

If you suppress an error, we recommend checking for the error condition explicitly:


// For example instead of
@mkdir($dir);

// Better use
if (@mkdir($dir) === false) {
    throw new \RuntimeException('The directory '.$dir.' could not be created.');
}

Are you sure the usage of header_remove('x-powered-by') is correct as it seems to always return null.
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
This check looks for function or method calls that always return null and whose
return value is used.


class A
{
    function getObject()
    {
        return null;
    }

}

$a = new A();
if ($a->getObject()) {





The method getObject() can return nothing but null, so it makes no sense
to use the return value.


The reason is most likely that a function or method is imcomplete or has been
