Since PHP can support COM and I usually use php in windows,
I try to use database like mssql through ado.
All things work properly but the image datatype of mysql cannot be set  correctly.
I use it just like this
<?
$dbconn=new COM("ADODB.Connection") or die ("connection create fail");
$dbconn->Open("Provider=sqloledb;Data Source=ndht;Initial Catalog=printers;User Id=printers;Password=printers;");
$fp=fopen("5.gif","r") or die ("file opening error");
$content = fread ($fp, filesize ("5.gif"));
fclose ($fp);
echo filesize ("5.gif");
$rec=new COM("ADODB.recordset");
$rec->open("select * from sav",$dbconn);
$rec->addnew();
$rec->fields["datas"]->AppendChunk($content);
$rec->update();
$rec->close();
$rec=null;
$dbconn->close();
$dbconn=null;
?>

I think that windows use two type text for strings and binary for the 8bit chars, but in php string are both of
these.
So when trans the data to mssql,the variables be string of
window first, and the information were lost.

hmm, this is a bit difficult because strings become usually translated into unicode which is usually a good thing(tm) but unfortunatelly not in this case.
as i'm actually rewriting the whole thing for php5/ZE2 i don't think that i'll address this yet.

harald

ps: don't use ado, it's sloooooooooooow :)

i think it is not necessary to rewrite,just use a function
like binarywrite() in asp(Active Server Page),
int binarywrite ($variant,$source)
return the length copied.

In PHP 4.4.2, I also encounter this ploblem.

I will store data as follows:
 00000000  ff d8 ff e0 00 10 4a 46  49 46 00 01 02 00 00 64  |......JFIF.....d|
 00000010  00 64 00 00 ff fe 00 12  41 64 6f 62 65 20 49 6d  |.d......Adobe Im|
 00000020  61 67 65 52 65 61 64 79  ff ec 00 11 44 75 63 6b  |ageReady....Duck|
 .
 .
 .


But, PHP really stores data as follows:
 00000000  00 00 10 00 4a 00 46 00  49 00 46 00 00 00 01 00  |....J.F.I.F.....|
 00000010  02 00 00 00 00 00 64 00  00 00 64 00 00 00 00 00  |......d...d.....|
 00000020  00 00 12 00 41 00 64 00  6f 00 62 00 65 00 20 00  |....A.d.o.b.e. .|
 .

May I reopen this issue?
Thanks.
