In this simple function you send two arrays and it gives you an array with the operation A-B, elements on A that are not included on B.

<?php
function RestaDeArrays($vectorA,$vectorB)

                                     {

                                       $cantA=count($vectorA);

                                       $cantB=count($vectorB);

                                       $No_saca=0;

                                       for($i=0;$i<$cantA;$i++)

                                            {

                                             for($j=0;$j<$cantB;$j++)

                                                  {

                                                   if($vectorA[$i]==$vectorB[$j])

                                                       $No_saca=1;


                                                  }

                            

                                             if($No_saca==0)

                                                $nuevo_array[]=$vectorA[$i];

                                               else

                                               $No_saca=0;

                                            }

                            

                                       return $nuevo_array;

                                     }
