foreach  array as  v  echo  v  PHP EOL    UPDATE  A more sophisticated solution would be     test          key1    gt   val1        key2    gt   val2        key3    gt             subkey1    gt   subval1            subkey2    gt   subval2            subkey3    gt                 subsubkey1    gt   subsubval1                subsubkey2    gt   subsubval2                        function printArray  arr   pad   0   padStr     t          outerPad    pad       innerPad    pad   1       out         PHP EOL      foreach   arr as  k   gt   v            if  is array  v                  out    str repeat  padStr   innerPad     k       gt      printArray  v   innerPad    PHP EOL            else                out    str repeat  padStr   innerPad     k       gt       v               out    PHP EOL                       out    str repeat  padStr   outerPad             return  out     echo printArray  test     This prints out                 key1   gt  val1         key2   gt  val2         key3   gt                subkey1   gt  subval1             subkey2   gt  subval2             subkey3   gt                    subsubkey1   gt  subsubval1                 subsubkey2   gt  subsubval2

For single arrays you can use implode  it has a cleaner result to print    lt  php  msg   array  msg1   msg2   msg3    echo implode   lt br   gt    msg   echo   lt br   gt ---------------------- lt br  gt     echo nl2br implode   n   msg    echo   lt br   gt ---------------------- lt br  gt      gt    For multidimensional arrays you need to combine with some sort of loop    lt  php  msgs      msg   msgs      msg   msgs      msg   msgs      msg   msgs      msg  foreach  msgs as  msg        echo implode   lt br   gt    msg       echo   lt br   gt ---------------------- lt br  gt        gt

print r   is mostly for debugging   If you want to print it in that format  loop through the array  and print the elements out   foreach  data as  d     foreach  d as  v       echo  v   n

I think that var export    the forgotten brother of var dump   has the best output - it s more compact   echo   lt pre gt    var export  menue   echo   lt  pre gt      By the way  it s not allway necessary to use  lt pre gt   var dump   and var export   are already formatted when you take a look in the source code of your webpage
