How can I count multiple lines for a loop with an array?

How can I count multiple lines for a loop with an array? when a new row entered into mysql database for a loop counts a new row as 0, when two new rows entered into mysql database for a loop count both rows as 1? I do not know why. for loop escape first row count start from second row?And also how to make several lines of a session with an array?

Request Function.php and Mysql

function get_wid($id){
    $result=mysql_query("SELECT id AS wid FROM mywishlist where pid='$id'") 
                or die("Id Problem"."<br/><br/>".mysql_error());
    $results= array();
    while($row=mysql_fetch_array($result)){
        $results[] = $row['wid'];
    }
    return $results;
}

Page function Where am I calling $ wid = get_wid ($ id);

$wid=get_wid($id);
$max1= count($wid);
for($i>0; $i<$max1; $i++)
{
    $wid1=$wid [$i].'<br />';   
    $_SESSION['wid2']=$wid1;
    echo $_SESSION['wid2'];
}

Now I use this function, now this function has not echoed or printed the value of count 0, but so far the values ​​are not displayed after count 1?

function get_wid($id){
$result=mysql_query("SELECT id AS wid FROM mywishlist where pid='$id'") or die("Id     Problem"."<br/><br/>".mysql_error());
$results= array();
$i=1; // add the new line
while($row=mysql_fetch_array($result)){
$results[$i] = $row['wid'];
$i++;
}
return $results;
}

$wid=get_wid($id);
$max1= count($wid);
for($i=1; $i<=$max1; $i++) // changes made here
{
$wid1=$wid [$i].'<br />';   
$_SESSION['wid2']=$wid1;
echo $_SESSION['wid2'];
}
