Data in jQuery ajax   function accepts anonymous objects as its input  see documentation  So example of what you re looking for is    dataString    key   val   key2   val2      ajax           type   POST           url   script php           data  dataString           cache  false           success  function                alert  OK                        You may also write POST GET query on your own  like key val amp key2 val2  but you d have to handle escaping yourself which is impractical

If you have been trying to send a one dimentional array and jquery was converting it to comma separated values     then follow the code below and an actual array will be submitted to php and not all the comma separated bull  it   Say you have to attach a single dimentional array named myvals    jQuery   someform   on  submit   function  e        e preventDefault        var data     this  serializeArray         var myvals    21  52  13  24  75      This array could come from anywhere you choose      for  i   0  i  lt  myvals length  i              data push               name   myvals        These blank empty brackets are imp              value  myvals i                     jQuery ajax       type   post       url  jQuery this  attr  action        dataType   json       data  data     You have to just pass our data variable plain and simple no Rube Goldberg sh t      success  function  r          Now inside php when you do this   print r   POST     You will get     Array        someinputinsidetheform    gt  023      anotherforminput    gt  111      myvals    gt  Array                        0    gt  21              1    gt  52              2    gt  13              3    gt  24              4    gt  75               Pardon my language  but there are hell lot of Rube-Goldberg solutions scattered all over the web and specially on SO  but none of them are elegant or solve the problem of actually posting a one dimensional array to php via ajax post  Don t forget to spread this solution

dataString suggests the data is formatted in a string  and maybe delimted by a character     data   explode        POST  data     foreach  data as  d        echo  d      if dataString is not a string but infact an array  what your question indicates  use JSON

Encode your data string into JSON   dataString            array  var jsonString   JSON stringify dataString        ajax           type   POST           url   script php           data   data   jsonString            cache  false           success  function                alert  OK                        In your PHP   data   json decode stripslashes   POST  data            here i would like use foreach     foreach  data as  d        echo  d        Note  When you send data via POST  it needs to be as a keyvalue pair    Thus  data  dataString  is wrong  Instead do   data   data dataString
