        introduced 
                            by 
            

        

        

            
        

        

            

                

                    
                
                
            


        

    

    

        
                        

                            
                                
                            
                        

                                        
The expression $expressions of type null|array is not guaranteed to be traversable. How about adding an additional type check?
                                                                                                                                                    

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
There are different options of fixing this problem.


  1. If you want to be on the safe side, you can add an additional type-check:
    

    $collection = json_decode($data, true);
if ( ! is_array($collection)) {
    throw new \RuntimeException('$collection must be an array.');
}

foreach ($collection as $item) { /** ... */ }

    

    

    2. 

  2. If you are sure that the expression is traversable, you might want to add a
doc comment cast to improve IDE auto-completion and static analysis:
    

    /** @var array $collection */
$collection = json_decode($data, true);

foreach ($collection as $item) { /** .. */ }
