array index changes

[moosoft]

I tried searching for this but I didn't find anything.  I have some php code that when loaded from a web page draws some numbers from a database and outputs.  Should be no problem I thought

 

The code involves a mysql query.  This is an edited sample:

$query = "SELECT `count` FROM `uc` WHERE `id` = 17";
$result = mysql_query($query, $dbh) or die(mysql_error());
$row = mysql_fetch_array($result, $dbh);

 

Now after this I normally access $row as $row[0] and this works great most of the time.  However about 10% of the time it returns an error: "Notice: Undefined offset: 0"

 

My investigation using print_r($row); shows that sometimes it returns Array ( [0] => 619 ) and sometimes it returns Array ( [count] => 619 )

 

Why the inconsistency?  How can I make it always use a numeric index?

If you read the documentation for mysql_fetch_array, you will learn that the second parameter is the result_type -

result_type

The type of array that is to be fetched. It's a constant and can take the following values: MYSQL_ASSOC, MYSQL_NUM, and MYSQL_BOTH.

Thank you so much!  I'll be sure to always specify that in the future.
