sql - How to iterate by row through a mysql query in php

Ok, So I am trying to query my database and select all rows that have a certain value. After that I turn the query into an array with mysql_fetch_array(), then I tried iterating by row through the fetched array using a for each loop.

<?php
$query = mysql_query("SELECT * FROM users WHERE pointsAvailable > 0 ORDER BY pointsAvailable Desc");
$queryResultArray = mysql_fetch_array($query);
foreach($queryResultArray as $row)
{
    echo $row['pointsAvailable'];
}
?>

Though when I do this for any column besides the pointsAvailable column say a column named "name" of type text it only returns a single letter.

How do I iterate through a returned query row by row, and be allowed to fetch specific columns of data from the current row?

$result = mysql_query("SELECT id, name FROM mytable");

while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
    printf("ID: %s  Name: %s", $row[0], $row[1]);  
}

or using MYSQL_ASSOC will allow you to use named columns

while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
    printf("ID: %s  Name: %s", $row["id"], $row["name"]);
}
