Question

I’m using PHP 5 with mySQL:

$line = mysql_fetch_array($result, MYSQL_ASSOC);

When I do this, I can see the results of the query printed:

foreach ($line as $data)
    {
        echo ($data . ", ");
    }

But if I do this instead:

echo ($line[0] . " " . $line[1] . " " . $line[2]);

I don’t see anything. Also I can’t assign a value from $line:

$values[] = $line[0]; // fails – doesn’t assign anything

Why? And what should I be doing instead?

Answer 1

You’ve nominated to retrieve records as associative entries only (MYSQL_ASSOC). This means your $line array will not contain numeric indices.

If you only want numeric arrays, use mysql_fetch_row().

Associative only, mysql_fetch_assoc()

You can also retrieve a mixed numeric and associative array using mysql_fetch_array($result, MYSQL_BOTH) however this will give you duplicate entries in your foreach loop.
