Since PHP is dynamically weakly typed  you can pass any variable to the function and the function will try to do its best with it   Therefore  you can indeed pass arrays as parameters

You can pass an array as an argument  It is copied by value  or COW d  which essentially means the same to you   so you can array pop    and similar  all you like on it and won t affect anything outside   function sendemail  id   userid                 sendemail array  a    b    c    10     You can in fact only accept an array there by placing its type in the function s argument signature     function sendemail array  id   userid                  You can also call the function with its arguments as an array     call user func array  sendemail   array  argument1    argument2
