structures in php ?

[Adrian Parker]

How do you create data structures in php ?

i.e. how would I create the following two vb structures in php ?

Structure SYSTEMTIME
Dim wYear As Short
Dim wMonth As Short
Dim wDayOfWeek As Short
Dim wDay As Short
Dim wHour As Short
Dim wMinute As Short
Dim wSecond As Short
Dim wMilliseconds As Short
End Structure

Private Structure TIME_ZONE_INFOR MATION
Dim Bias As Integer
Dim StandardBias As Integer
Dim DaylightBias As Integer
Dim StandardDate As SYSTEMTIME
Dim DaylightDate As SYSTEMTIME
End Structure

Also, if I read a binary value from the registry, how would I then convert it to a variable of type TIME_ZONE_INFOR MATION


Many Thanks

Two solutions :
1/ the Q&D way : use an associative array :
$sys_time = Array();
$sys_time['wYear'] = 2004;
$sys_time['wMonth'] = 12;

etc...

2/ the clean way : use classes :

class SystemTime {
function SystemTime($yea r, $month, $dayOfWeek, [etc...]) {
$this->wYear = $year;
$this->wMonth = $month;
$this->wDayOfWeek = $dayOfWeek;

etc...
}
}

convert it to a variable of type TIME_ZONE_INFOR MATION

ask a MS-Windows group...

Ok, lets put it another way.

Say I have a blob in a db that was populated from another source.

when I select the blob, I just have binary data.. how do I split that up into the individual structure components ?

PHP does not have support for Structures or structs in the traditional
sense. You can use an associative array instead to simulate the
structure and it's members.

I'm not sure this will help, but you may want to have a look at :

http://www.php.net/manual/en/function.pack.php

http://www.php.net/manual/en/function.unpack.php

http://www.php.net/manual/en/function.bin2hex.php

Else you may have to manually parse your binary data.
