I figured it out on my own!
It's probably not the best way (I am just a beginner in this stuff) but it works.
So I was trying to put the data from my database into an array. The code in my original post was just a sample version because I wanted to try the code first.
This is what I came up with. The PHP:
$array = array();
while($row = mysql_fetch_assoc($rs)){ //$rs is mySQL query
$array[] = $row;
}
echo $array[0]['post']. '&'; //post is the column name from my database
echo $array[1]['post']. '&';
echo $array[2]['post'];
With Ajax I did this (thanks to stefanz!):
$.ajax({
method: 'GET',
url: 'test.php',
cache: false,
success: function(data){
var tmp = data.split("&");
$('#showValue1').html(tmp[0]);
$('#showValue2').html(tmp[1]);
$('#showValue3').html(tmp[2]);
}
});
Thanks everybody for helping me out! It lead me to the code I am using now.
