[RESOLVED] Unexpected T_DOUBLE_ARROW problem

[Staggy11]

I'm updating an array stored in a DB. I've got the array from the DB, unserialised it, and am trying to push a new item onto the end. However, I want the index to be a timestamp, but when I use this code :

$time=time();
$new=$_POST['speech'];
array_push($speech_array, $time=>$new);

I get the error message "Unexpected T_DOUBLE_ARROW". Is there a way around this, or am I missing something very basic?

I think array_push is for numeric arrays not associative.

To add the variable to the array use:

$time=time();
$new=$_POST['speech'];
$speech_array[$time] = $new;

That got rid of the double arrows problem, but brought up another. Here is the entire code:

<?
include 'db.php';
if(isset($HTTP_POST_VARS['submit'])){

//get old
$speech_query=mysql_query("SELECT * FROM map WHERE `x` = '". $object[5]->x ."' AND `y` = '". $object[5]->y ."'") or die(mysql_error());
$speech_array=array();
if (!is_array($speech_array)){die("NOPE");}
$array_info = mysql_fetch_array($speech_query);
$speech_array=unserialize($array_info['speech']);


//add new
$time=time();
$new=$_POST['speech'];
$speech_array[$time] = $new;

$info=mysql_real_escape_string(serialize($speech_array));
$update=mysql_query("UPDATE `map` SET `speech`= '$info' WHERE x='2' AND y='2' ") or die(mysql_error()); 
mysql_free_result($speech_query);
}else{
?>
<form name="signup" action="<? $_SERVER['PHP_SELF']; ?>" method="POST">
 <tr>
     <td><input type="text" id ="speech" name="speech" value="" maxlength="30"></td>
<td><input type="submit" id="submit" name="submit" value="submit"></td></form><?}?>

The new text is replacing the entire array, not being put on the end. Why is this?
