Question

I am sending an array in php (converted from a string using explode), to a seperate javascript page. I was wondering how do I get into the javascript array and actually retrieve data values.

array in javascript (from php file)-

array(2) {
  [0]=>
  string(2) "30"
  [1]=>
  string(0) ""
}
array(2) {
  [0]=>
  string(2) "30"
  [1]=>
  string(0) ""
}

Here is the ajax call on the javascript page –

$.ajax({
    url: "GetTest.php",
    type: "POST",
    success: function(data){
     alert("success");
     console.log(data);  
    },
    error: function(data){
     alert('failure'); 
    }
});

on the php page –

var_dump((explode(',', $something));

How do I get in here and pull out the “30” value. I am using an ajax call to get this data, and then putting placing this array in a variable called “data”, but if I do something like data[0], I get the letter “a” as a response.
Any help towards this will be greatly appreciated.
Thanks,

A JavaScript array should look like this…

var myArray = ["30", "0"];

You probably have a string instead of an array if you get an ‘a’ at index 0.

"array"[0] === "a"

So you need to fix your client side array first.
