PHP 5.4.31 Released

sybase_fetch_assoc

(PHP 4 >= 4.3.0, PHP 5)

sybase_fetch_assocFetch a result row as an associative array

Descrizione

array sybase_fetch_assoc ( resource $result )

sybase_fetch_assoc() is a version of sybase_fetch_row() that uses column names instead of integers for indices in the result array. Columns from different tables with the same names are returned as name, name1, name2, ..., nameN.

An important thing to note is that using sybase_fetch_assoc() is NOT significantly slower than using sybase_fetch_row(), while it provides a significant added value.

Elenco dei parametri

Valori restituiti

Very often you see constructs like this to loop thru a result set:

while ($row = sybase_fetch_assoc($result))
{
    while (current($row)) // or  while (current($row) != false)
    {
        $data = current($row);
        $key = key($row);
               
        //
        // do stuff here
        //
       
    next($row);   
    }
}

Do not use it in this way! You have to write the inner while loop this way:

while (current($row) !== false)

If you just use
while (current($row) != false)
or
while (current($row))

you could be in trouble and loose some data. In my case I had a query which contained the following statement:

datediff(dd, date1, date2) as days

Now if days computes to 0 then the two while loop examples from above will exit (because the 0 is 'seen' as false). Therefore you must use while (current($row) !== false) which will not exit if one of you data contains 0.

For users that want this function in other applications, use this function.  I have been using it for over a year with great success.

function sybase_fetch_assoc($query_result){
        $row = sybase_fetch_array($query_result);
        $values = "";
        if(is_array($row))
        {
        while(list($key, $val) = each($row))
            {
                $values[$key] = $val;
            }
        }
    return $values;
}
