Good, I have a variable session called api where I have two words stored

echo $_SESSION["api"]['0']; This would be parabra1 echo $_SESSION["api"]['0']; This would be word 2

This variable is in a php file and is returned to an ajax function in success: function(data){

From the php file I do echo $_SESSION["api"];

When I go through data with a for, what I need is for you to show me the two words: word1 and word 2, and the result I get is 'p''a''l''a' etc ..

for(var i = 0; i < data.length; i++){
            alert(data[i])
    }

What am I doing wrong? Thank you very much.

You have to return each index from where you save the words separately as an array and then convert it to json and return it:

$arr = array();
$arr[0] = $_SESSION["api"];

echo json_encode($arr);

And now if you can get the full word:

//..
.success(function(data){
  for(var i = 0; i < data.length; i++){
       alert(data[i])
    }
})

And actually I do not know if it's a graphic type error but you're saving both the value of word1 and word2 in the same key api $_SESSESION["api"] . You should assign a different key for both words:

$_SESSION["api1"] = "palabra1";
$_SESSION["api2"] = "palabra2";

$arr = array();
$arr[0] = $_SESSION["api1"];
$arr[1] = $_SESSION["api2"];

echo json_encode($arr);
