Mysqli with unknown bind_results - php

Question

Ok, I thought I had this, but I can't see why it's not working...
I have a SELECT with a variable table, hence my columns (bind_result) is going to be variable.
I need to adjust for any number of columns coming back, and fetch as an associated array, since there will be multiple rows coming back:
// Get table data
$mysqli = new mysqli('host','login','passwd','db');
if ($mysqli->connect_errno()) { $errors .= "<br>Cannot connect: ".$mysqli->connect_error()); }
$stmt = $mysqli->prepare("SELECT * FROM ?");
$stmt->bind_param('s', $table);
$stmt->execute();
// Get bind result columns
$fields = array();
// Loop through columns, build bind results
for ($i=0; $i < count($columns); $i++) {
$fields[$i] = ${'col'.$i};
}
// Bind Results
call_user_func_array(array($stmt,'bind_result'),$fields);
// Fetch Results
$i = 0;
while ($stmt->fetch()) {
$results[$i] = array();
foreach($fields as $k => $v)
$results[$i][$k] = $v;
$i++;
}
// close statement
$stmt->close();
Any thoughts are greatly appreciated ^_^
EDIT: New code:
$mysqli = new mysqli('host','login','passwd','db');
if ($mysqli->connect_errno)) { $errors .= "<br>Cannot connect: ".$mysqli->connect_error()); }
$stmt = "SELECT * FROM ".$table;
if ($query = $mysqli->query($stmt)) {
$results = array();
while ($result = $query->fetch_assoc()) {
$results[] = $result;
}
$query->free();
}
$mysqli->close();

You can not bind the table name. Bind_param accept the column name and its datatype.
To use the table name dynamically use the below code:
$stmt = $mysqli->prepare("SELECT * FROM ".$table);
