I need to return multiple values from a function  therefore I have added them to an array and returned the array   lt   function data         a    quot abc quot        b    quot def quot        c    quot ghi quot        return array  a   b   c       gt   How can I receive the values of  a   b   c by calling the above function

The data function is returning an array  so you can access the result of the function in the same way as you would normally access elements of an array    lt  php      result   data      a    result 0    b    result 1    c    result 2     Or you could use the list   function  as  fredrik recommends  to do the same thing in a line

In order to get the values of each variable  you need to treat the function as you would an array   function data          a    abc        b    def        c    ghi       return array  a   b   c         Assign a variable to the array      I selected  dataArray  could be any name     dataArray   data    list  a   b   c     dataArray  echo  a         b          c     if you just need 1 variable out of 3  list    b       dataArray  echo  b

From PHP 5 4 you can take advantage of array dereferencing and do something like this    lt    function data          retr arr  a      abc        retr arr  b      def        retr arr  c      ghi        return  retr arr      a   data    a          a    abc   b   data    b          b    def   c   data    c          c    ghi    gt

The underlying problem revolves around accessing the data within the array  as Felix Kling points out in the first response    In the following code  I ve accessed the values of the array with the print and echo constructs    function data           a    abc        b    def        c    ghi         array   array  a   b   c        print r  array    outputs the key value pair      echo   lt br gt         echo  array 0   array 1   array 2    outputs a concatenation of the values     data

You can add array keys to your return values and then use these keys to print the array values  as shown here   function data          out  a      abc        out  b      def        out  c      ghi       return  out      data   data    echo  data  a    echo  data  b    echo  data  c

I was looking for an easier method than i m using but it isn t answered in this post  However  my method works and i don t use any of the aforementioned methods   function MyFunction        lookyHere   array       value1    gt  array  valuehere         entry2    gt  array  valuehere          return  lookyHere      I have no problems with my function  I read the data in a loop to display my associated data  I have no idea why anyone would suggest the above methods  If you are looking to store multiple arrays in one file but not have all of them loaded  then use my function method above  Otherwise  all of the arrays will load on the page  thus  slowing down your site  I came up with this code to store all of my arrays in one file and use individual arrays when needed

Your function is   function data      a    abc    b    def    c    ghi    return array  a   b   c       It returns an array where position 0 is  a  position 1 is  b and position 2 is  c  You can therefore access  a by doing just this   data   0   If you do  myvar   data   0  and print  myvar  you will get  abc   which was the value assigned to  a inside the function

I think the best way to do it is to create a global var array  Then do whatever you want to it inside the function data by passing it as a reference  No need to return anything too    array   array  white    black    yellow    echo  array 0     this echo white data  array    function data  amp  passArray      lt  lt notice  amp       passArray 0     orange      echo  array 0     this now echo orange
