Date conversion and comparison

[bob0209]

iam kinda new to PHP, lucky to have this site.

i have a problem, iam getting the date from the user in a text item and writing to a text file in the format dd-mm-yy(18-11-02)

then when i open a page iam reading the date from the text file and stroing into a vaiable $mydate and then iam comparing with Systemdate inthe same format that is $sysdate =date("d-m-y")
now the problem starts

i want to see if $mydate > $sysdate the $mydate is in in string string format how do i compare this can some one help with the code.

advance thanks

Well to do that you have to make both a timestamp(that will bee in EPOCH format, that way you can compare them,

mktime() accepts up to six integer arguments in the
following order:
hour
minute
second
month
day of month
year

so you want to use it like this

$time = mktime(0,0,0,01,01,2002)

that would give you the time stamp for Jan 1, 2002

then once you make them into a timestamp you can compare them

since we can use mktime to change date 04/01/2003 to apr, 1 2003

but how to change apr,1 2003 to 04/01/2003 ???
thank ur reply

Use strtotime to change it to timestamp, then use date...

Could probably combine the two...

date("datebits", (".strtotime(Apr 1 2003)."));

Maybe...
