Onde vai desenvolver ? WIN, Linux ??
Eu optaria pelo Linux !
O ubuntu Ultimate é bem completo ( http://ultimateedition.info/ )

Sim,
Mas você tem que gravar o ID dele em uma session
e quando for fazer o select, update ou delete você poe o WHERE ID = session dele
$sql= mysql_query("SELECT * FROM tb_usuarios WHERE ID_USUARIO = '".$_SESSION[id]."'") or die("ERRO NA CONSULTA SQL"); -
Não tem secredo fazer um
basta você ter a tabela da financeira com os multiplicadores x os numeros de parcelas !
já fiz um para uma loja de veiculos online.

procure estudar sobre
sistema de autenticação com session
veja se ajuda

Link http://dev.mysql.com/doc/refman/5.0/en/str...unction_replace
Seria bom falar como resolveu, assim poderá servir para os demais que tiverem a mesma dúvida !
-
Simples da um replace em TUDO no banco antes !
No banco fica tudo sem mascara, a mascara você so mostra
no ato de exibir !
Vai ser a melhor forma pra você !

NAME time - This module provides various functions to manipulate time values. FILE (built-in) DESCRIPTION There are two standard representations of time. One is the number of seconds since the Epoch, in UTC (a.k.a. GMT). It may be an integer or a floating point number (to represent fractions of seconds). The Epoch is system-defined; on Unix, it is generally January 1st, 1970. The actual value can be retrieved by calling gmtime(0). The other representation is a tuple of 9 integers giving local time. The tuple items are: year (four digits, e.g. 1998) month (1-12) day (1-31) hours (0-23) minutes (0-59) seconds (0-59) weekday (0-6, Monday is 0) Julian day (day in the year, 1-366) DST (Daylight Savings Time) flag (-1, 0 or 1) If the DST flag is 0, the time is given in the regular time zone; if it is 1, the time is given in the DST time zone; if it is -1, mktime() should guess based on the date and time. Variables: timezone -- difference in seconds between UTC and local standard time altzone -- difference in seconds between UTC and local DST time daylight -- whether local time should reflect DST tzname -- tuple of (standard time zone name, DST time zone name) Functions: time() -- return current time in seconds since the Epoch as a float clock() -- return CPU time since process start as a float sleep() -- delay for a number of seconds given as a float gmtime() -- convert seconds since Epoch to UTC tuple localtime() -- convert seconds since Epoch to local time tuple asctime() -- convert time tuple to string ctime() -- convert time in seconds to string mktime() -- convert local time tuple to seconds since Epoch strftime() -- convert time tuple to string according to format specification strptime() -- parse string to time tuple according to format specification tzset() -- change the local timezone CLASSES __builtin__.object struct_time class struct_time(__builtin__.object) | Methods defined here: | | __add__(...) | x.__add__(y) <==> x+y | | __contains__(...) | x.__contains__(y) <==> y in x | | __eq__(...) | x.__eq__(y) <==> x==y | | __ge__(...) | x.__ge__(y) <==> x>=y | | __getitem__(...) | x.__getitem__(y) <==> x[y] | | __getslice__(...) | x.__getslice__(i, j) <==> x[i:j] | | Use of negative indices is not supported. | | __gt__(...) | x.__gt__(y) <==> x>y | | __hash__(...) | x.__hash__() <==> hash(x) | | __le__(...) | x.__le__(y) <==> x<=y | | __len__(...) | x.__len__() <==> len(x) | | __lt__(...) | x.__lt__(y) <==> x<y | | __mul__(...) | x.__mul__(n) <==> x*n | | __ne__(...) | x.__ne__(y) <==> x!=y | | __reduce__(...) | | __repr__(...) | x.__repr__() <==> repr(x) | | __rmul__(...) | x.__rmul__(n) <==> n*x | | ---------------------------------------------------------------------- | Data descriptors defined here: | | tm_hour | | tm_isdst | | tm_mday | | tm_min | | tm_mon | | tm_sec | | tm_wday | | tm_yday | | tm_year | | ---------------------------------------------------------------------- | Data and other attributes defined here: | | __new__ = <built-in method __new__ of type object at 0x1E1F50A0> | T.__new__(S, ...) -> a new object with type S, a subtype of T | | n_fields = 9 | | n_sequence_fields = 9 | | n_unnamed_fields = 0 FUNCTIONS asctime(...) asctime([tuple]) -> string Convert a time tuple to a string, e.g. 'Sat Jun 06 16:26:11 1998'. When the time tuple is not present, current time as returned by localtime() is used. clock(...) clock() -> floating point number Return the CPU time or real time since the start of the process or since the first call to clock(). This has as much precision as the system records. ctime(...) ctime(seconds) -> string Convert a time in seconds since the Epoch to a string in local time. This is equivalent to asctime(localtime(seconds)). When the time tuple is not present, current time as returned by localtime() is used. gmtime(...) gmtime([seconds]) -> (tm_year, tm_mon, tm_mday, tm_hour, tm_min, tm_sec, tm_wday, tm_yday, tm_isdst) Convert seconds since the Epoch to a time tuple expressing UTC (a.k.a. GMT). When 'seconds' is not passed in, convert the current time instead. localtime(...) localtime([seconds]) -> (tm_year,tm_mon,tm_mday,tm_hour,tm_min,tm_sec,tm_wday,tm_yday,tm_isdst) Convert seconds since the Epoch to a time tuple expressing local time. When 'seconds' is not passed in, convert the current time instead. mktime(...) mktime(tuple) -> floating point number Convert a time tuple in local time to seconds since the Epoch. sleep(...) sleep(seconds) Delay execution for a given number of seconds. The argument may be a floating point number for subsecond precision. strftime(...) strftime(format[, tuple]) -> string Convert a time tuple to a string according to a format specification. See the library reference manual for formatting codes. When the time tuple is not present, current time as returned by localtime() is used. strptime(...) strptime(string, format) -> struct_time Parse a string to a time tuple according to a format specification. See the library reference manual for formatting codes (same as strftime()). time(...) time() -> floating point number Return the current time in seconds since the Epoch. Fractions of a second may be present if the system clock provides them. DATA accept2dyear = 1 altzone = 7200 daylight = 0 timezone = 10800 tzname = ('Hora oficial do Brasil', 'Hora oficial do Brasil')
