You need to turn this into a string  You can do this using the stringify method in the JSON2 library   http   www json org   http   www json org js html  The code would look something like   var myJSONText   JSON stringify myObject     So     Location Zero    Location One    Location Two      Will become      Location Zero    Location One    Location Two      You ll have to refer to a PHP guru on how to handle this on the server  I think other answers here intimate a solution   Data can be returned from the server in a similar way  I e  you can turn it back into an object   var myObject   JSON parse myJSONString

You ll want to encode your array as JSON before sending it  or you ll just get some junk on the other end   Since all you re sending is the array  you can just do   data    activities  activities     which will automatically convert the array for you   See here for details

I know it may be too late to answer this  but this worked for me in a great way    Stringify your javascript object  json  with var st   JSON stringify your object   Pass your POST data as  string   maybe using jQuery    post  foo php   data st  function data          Decode your data on the server-side processing   data   json decode   POST  data       That s it    you can freely use your data   Multi-dimensional arrays and single arrays are handled as normal arrays  To access them just do the normal  foo 4    Associative arrays  javsacript objects  are handled as php objects  classes   To access them just do it like classes   foo- gt bar

Use the JQuery Serialize function  http   docs jquery com Ajax serialize     Serialize is typically used to prepare   user input data to be posted to a   server  The serialized data is in a   standard format that is compatible   with almost all server side   programming languages and frameworks

Use the PHP built-in functionality of the appending the array operand to the desired variable name   If we add values to a Javascript array as follows   acitivies push  Location Zero    acitivies push  Location One    acitivies push  Location Two      It can be sent to the server as follows     ajax                  type   POST          url   tourFinderFunctions php           activities     activities        success  function                     lengthQuestion   fadeOut  slow                           Notice the quotes around activities    The values will be available as follows     POST  activities   0      Location Zero     POST  activities   1      Location One     POST  activities   2      Location Two

This is because PHP reads your value as a string  If I don t want to pass my data as an object  like in the previous answers  which are also fine   I just do this in my PHP     activitiesString     POST  activitiesArray      activitiesArray    explode      activitiesString      The last line splits string into bits after every comma  Now  activitiesArray is also an array  It works even if there is no comma  only one element in your javascript array    Happy coding
