I know its a bit late now  but you could do something such as this   function AddToArray   post information          Create the return array      return   array          Iterate through the array passed     foreach   post information as  key   gt   value              Append the key and value to the array  e g                  POST  keys      values  would be in the array as  keys   gt  values           return  key     value              Return the created array     return  return      The test with   if  isset   POST  submit           var dump AddToArray   POST        This for me produced   array  size 1    0   gt       array  size 5         stake    gt  string  0   length 1         odds    gt  string     length 0         ew    gt  string  false   length 5         ew deduction    gt  string     length 0         submit    gt  string  Open   length 4

E g  by naming the fields like   lt input type  text  name  item 0  name     gt   lt input type  text  name  item 0  email     gt    lt input type  text  name  item 1  name     gt   lt input type  text  name  item 1  email     gt    lt input type  text  name  item 2  name     gt   lt input type  text  name  item 2  email     gt     which is also possible when adding elements via javascript   The corresponding php script might look like  function show Names  e      return  The name is  e name  and email is  e email   thank you       c   array map  show Names     POST  item     print r  c

Nonetheless  you can use below code as    a   array  name1   name2   name3     b   array  email1   email2   email3     function f  a  b       return  The name is  a and email is  b  thank you       c   array map  f    a   b      echoing the result  foreach   c as  val        echo  val   lt br gt

They are already in arrays   name is an array  as is  email  So all you need to do is add a bit of processing to attack both arrays    name     POST  name     email     POST  account     foreach   name as  key   gt   n       print  The name is    n   and email is    email  key     thank you n       To handle more inputs  just extend the pattern    name     POST  name     email     POST  account     location     POST  location     foreach   name as  key   gt   n       print  The name is    n    email is    email  key              and location is    location  key     Thank you n

What if you ve got array of fieldsets    lt fieldset gt   lt input type  text  name  item 1     gt   lt input type  text  name  item 2     gt   lt input type  hidden  name  fset     gt   lt  fieldset gt    lt fieldset gt   lt input type  text  name  item 3     gt   lt input type  text  name  item 4     gt   lt input type  hidden  name  fset     gt   lt  fieldset gt    I added a hidden field to count the number of the fieldsets  The user can add or delete the fields and then save it

However  VolkerK s solution is the best to avoid miss couple between email and username  So you have to generate HTML code with PHP like this    lt   foreach   i   0   i  lt   total data   i        gt       lt input type  text  name  name  lt     i   gt      gt       lt input type  text  name  email  lt     i   gt      gt   lt   endforeach    gt    Change  total data to suit your needs  To show it  just like this    output   array map create function   name   email    return  The name is  name and email is  email  thank you         POST  name      POST  email     echo implode   lt br gt     output     Assuming the data was sent using POST method

I came across this problem as well  Given 3 inputs  field    field2    field3    You can access each of these fields dynamically  Since each field will be an array  the related fields will all share the same array key  For example  given input data    Bob  bob bob com  male Mark  mark mark com  male   Bob and his email and sex will share the same key  With this in mind  you can access the data in a for loop like this       for  x   0   x  lt  count  first name    x                   echo  first name  x           echo  email  x           echo  sex  x           echo   lt br  gt            This scales as well  All you need to do is add your respective array vars whenever you need new fields to be added
