I think the better answer for this questions is

array_diff()

because it Compares array against one or more other arrays and returns the values in array that are not present in any of the other arrays.

Whereas

array_intersect() returns an array containing all the values of array that are present in all the arguments. Note that keys are preserved.

OK   We needed to compare a dynamic number of product names     There s probably a better way    but this works for me         because    Strings are just Arrays of characters              Compare Strings      Return Matching Text and Differences with Product IDs         From MySql     productID1    abc123    productName1    EcoPlus Premio Jet 600        productID2    xyz789    productName2    EcoPlus Premio Jet 800        ProductNames   array       productID1   gt   productName1       productID2   gt   productName2      function compareNames  ProductNames               Convert NameStrings to Arrays            foreach  ProductNames as  id   gt   product name            Package1  id    explode      product name                     Get Matching Text         Matching   call user func array  array intersect    Package1         MatchingText   implode      Matching            Get Different Text        foreach  Package1 as  id   gt   product name chunks            Package2   array  product name chunks  Matching            diff   call user func array  array diff    Package2             DifferentText  id    trim implode       diff                results  MatchingText      DifferentText                    return  results          Results    compareNames  ProductNames    print r  Results       Gives us this     EcoPlus Premio Jet            abc123    gt  600          xyz789    gt  800
