i have created a function i found useful. i am sure there are better ways to doing this and it doesn't do much error checking but you get the idea and how this may be a useful feature...

/**
 ** this function will take in an array with keyed values
 ** and place the values into the
 ** same name columns as the key name.
 **
 ** bool mysql_insert_array(array, table_name)
 **
 ** ie...
 **
 **      $array = array("id" => $id, "md5" => md5($id));
 **
 **      mysql_insert_array($array, "users");
 **/
function mysql_insert_array($array, $table) {

    $keys = array_keys($array);

    for ($index = 0; $index < count($array); $index++) {

        if ($index != 0) {
            $columns .= ",";
            $values .= ",";
        }

        /** construct the column names from the array **/
        $columns .= $keys[$index];

        if (is_int($array[$keys[$index]])) {
            $values .= $array[$keys[$index]];
        } else {
            $values .= "'" . mysql_real_escape_string($array[$keys[$index]]) . "'";
        }
    }

    $query = "INSERT INTO `" . $table . "` (" . $columns . ") VALUES (" . $values . ")";
    
    if (($result = mysql_query($query)) == 0)
        return(0);

    if (mysql_affected_rows() == 1)
        return(1);
    else
        return(0);
}
