sybase_fetch_assoc — Fetch a result row as an associative array

Warning

This function was REMOVED in PHP 7.0.0.

설명

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.

인수

result

반환값

Returns an array that corresponds to the fetched row, or FALSE if there are no more rows.

주의

Note: 이 함수는 Sybase를 CT 라이브러리 인터페이스로 이용할 때만 사용할 수 있으며, DB 라이브러리로는 사용할 수 없습니다.

참고

sybase_fetch_row() - Get a result row as an enumerated array
sybase_fetch_array() - Fetch row as array
sybase_fetch_object() - Fetch a row as an object

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;
}
