As you need to see the result for testing purpose  The simple and elegant solution is the below code  echo  quot  lt pre gt  quot   print r   POST   echo  quot  lt  pre gt  quot

Just   foreach     POST as  key   gt   value       echo   lt p gt    key   lt  p gt      echo   lt p gt    value   lt  p gt      echo   lt hr   gt

POST is already an array  so you don t need to wrap array   around it   Try this instead    lt  php    for   i 0  i lt count   POST  id     i         echo   lt p gt     POST  id    i    lt  p gt      echo   lt p gt     POST  value    i    lt  p gt      echo   lt hr   gt            gt    NOTE  This works because your id and value arrays are symmetrical  If they had different numbers of elements then you d need to take a different approach

lt  php    foreach    POST as  key   gt   value      echo   lt p gt    key   lt  p gt      foreach  value as  k   gt   v        echo   lt p gt    k   lt  p gt      echo   lt p gt    v   lt  p gt      echo   lt hr   gt                gt    this will work  your first solution is trying to print array  because your value is an array

Because you have nested arrays  then I actually recommend a recursive approach   function recurse into array   in   tabs              foreach   in as  key   gt   item                 echo  tabs    key       gt             if  is array   item                           recurse into array   item   tabs     t                       else                       echo  tabs     t     key                     recurse into array    POST

Why are you wrapping the   POST array in an array   You can access your  id  and  value  arrays using the following     assuming the appropriate isset   checks for   POST  id   and   POST  value     ids     POST  id     values     POST  value     foreach   ids as  idx   gt   id                  foreach   values as  idx   gt   value

The foreach loops work just fine  but you can also simply  print r   POST     Or for pretty printing in a browser   echo   lt pre gt    print r   POST   echo   lt  pre gt

POST is an array in itsself you don t need to make an array out of it  What you did is nest the   POST array inside a new array  This is why you print Array  Change it to   foreach    POST as  key   gt   value       echo   lt p gt    key   lt  p gt      echo   lt p gt    value   lt  p gt      echo   lt hr   gt

You are adding the   POST array as the first element to  myarray  If you wish to reference it  just do    myarray     POST    However  this is probably not necessary  as you can just call it via   POST in your script
