As Jason ([email protected]) as demonstrated in his code example, there is a
PHP database wrapper class library that can connect to ADO available
called ADODB.
It is available from and
supports many databases both on Windows and Linux.
Modelled after
ADO, so it should be easy for Windows programmers to learn.

I thought i'd share with those of you unfamiliar with one of the cool
things
about developing php on win32 systems..
This
is a good article, but i don't think the author hit the nail on
the
head showing how useful this can be.
Now, checkout this
article:
Notice
how he describes 1) how to build a com object & 2) how to call
and
use the com object from ASP.
In php, this is how you
would call the same object:
<?
$instance = new
COM("Checkyear.LeapYear");
$isleapyear =
$instance->IsLeapYear($year);
$instance->close();
if($isleapyear)
{
echo "The <b>$year</b> is a leap
year";
}
else {
echo "The <b>$year</b>
is not a leap year";
}
?>
I hope this helps
someone.. you can contact me at [email protected] if
you would like
to discuss this further.

now in PHP >=4.0.6
programming in window can use the
ADO through
the COM 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;");
$rec=new
COM("ADODB.Recordset") or die ("create Recordset
error");
while (!$rec->EOF)
{
echo
$rec->fields["fieldname"]->value."
";
$rec->movenext();
}
$rec->close();
$dbconn->close();
but there's still
a little question of working with the image field of mssql server.

I thought this excel chart example could be useful.
Note the use of
Excel.application vs Excel.sheet.
<pre>
<?php
print "Hi";
#Instantiate the spreadsheet component.
#
$ex = new COM("Excel.sheet") or Die ("Did not
connect");
$exapp = new COM("Excel.application") or Die
("Did not connect");
#Get the application name and
version
print "Application
name:{$ex->Application->value}
" ;
print "Loaded
version: {$ex->Application->version}
";
$wkb=$exapp->Workbooks->add();
#$wkb =
$ex->Application->ActiveWorkbook or Die ("Did not open
workbook");
print "we opened
workbook
";
$ex->Application->Visible = 1; #Make
Excel visible.
print "we made excell
visible
";
$sheets = $wkb->Worksheets(1); #Select the
sheet
print "selected a sheet
";
$sheets->activate;
#Activate it
print "activated sheet
";
#This is a
new sheet
$sheets2 = $wkb->Worksheets->add(); #Add a sheet
print "added a new sheet
";
$sheets2->activate;
#Activate it
print "activated
sheet
";
$sheets2->name="Report Second
page";
$sheets->name="Report First
page";
print "We set a name to the sheet:
$sheets->name
";
# fills a columns
$maxi=20;
for
($i=1;$i<$maxi;$i++) {
$cell = $sheets->Cells($i,5) ; #Select
the cell (Row Column number)
$cell->activate; #Activate the
cell
$cell->value = $i*$i; #Change it to 15000
}
$ch
= $sheets->chartobjects->add(50, 40, 400, 100); # make a
chartobject
$chartje = $ch->chart; # place a chart in the chart
object
$chartje->activate; #activate chartobject
$chartje->ChartType=63;
$selected =
$sheets->range("E1:E$maxi"); # set the data the chart uses
$chartje->setsourcedata($selected); # set the data the chart uses
print "set the data the chart uses
";
$file_name="D:/apache/Apache/htdocs/alm/tmp/final14.xls";
if
(file_exists($file_name))
{unlink($file_name);}
#$ex->Application->ActiveWorkbook->SaveAs($file_name);
# saves sheet as final.xls
$wkb->SaveAs($file_name); # saves sheet
as final.xls
print
"saved
";
#$ex->Application->ActiveWorkbook->Close("False");
$exapp->Quit();
unset($exapp);
?>

An easy way to send e-mail using your default Outlook
account:
<?
$objApp = new
COM("Outlook.Application");
$myItem =
$objApp->CreateItem(olMailItem);
$a=$myItem->Recipients->Add("[email protected]");
$myItem->Subject="Subject";
$myItem->Body="This
is a Body Section
now.....!";
$myItem->Display();
$myItem->Send();
?>

an easy way to convert your file from .doc to .html
// starting
word
$word = new COM("word.application") or die("Unable
to instanciate Word");
// if you want see thw World interface
the value must be '1' else '0'
$word->Visible = 1;
//doc file
location
$word->Documents->Open("E:\\first.doc");
//html
file location '8' mean HTML
format
$word->Documents[1]->SaveAs("E:\\test_doc.html",8);
//closing
word
$word->Quit();
//free the object from the
memory
$word->Release();
$word = null;

Complementing Alex's Excell Example, let's print the SpreadSheet to a PDF
file using Acrobat Distiller:
$wkb->PrintOut(NULL, NULL, NULL,
NULL, "Acrobat Distiller");
There you go!!!

This is a sample to make a parametrized query using ADO via COM, this
sample was used with Foxpro but will work's with most ADO complient
databases. This was tested on IIS with WIN XP pro.
<?
//
Create the main connection
$dbc = new COM("ADODB.Connection")
or die ("connection create fail");
$dbc->Provider =
"MSDASQL";
$dbc->Open("FoxDatabase");
//
Creates a temporary record set
$RSet = new
COM("ADODB.Recordset");
// Create one ADO command
$cm =
new COM("ADODB.Command");
$cm->Activeconnection =
$dbc;
// the ? inside values will be the parameters $par01 and
$par02
$cm->CommandText = "Insert Into testtable (
mycharfield,mymemofield) VALUES (?,?)" ;
$cm->Prepared =
TRUE;
// Creates and append 2 parameters
$par01 =
$cm->CreateParameter('ppar01',129,1,50,'ABCDEFGHIKL');
$cm->Parameters->Append($par01);
$par02
=
$cm->CreateParameter('ppar01',129,1,50,'123456789012346789');
$cm->Parameters->Append($par02);
//
Call 10 times the exec comand to show 10 different queries
for ($i = 1;
$i <= 10; $i++) {
$par01->Value = 'Count '.$i;
$par02->Value = 'Passing here'.$i.' times';
$RSet =
$cm->Execute;
}
$RSet = $dbc->Execute("select * from
testtable");
while (!$RSet->EOF){
echo
$RSet->fields["mycharfield"]->value.' ' ;
echo
$RSet->fields["mymemofield"]->value ;
echo
'
';
$RSet->movenext();
}
$RSet->close;
$dbc->close;
$cm->close;
$RSet
= null;
$dbc = null;
$cm = null;
?>

When first writing applications instancing COM objects I always faced the
problem of the instanced program not terminating correctly although
everything else worked fine. In fact the process had to be killed manually
by using the task manager. When experimenting a bit I was able to isolate
the cause for this peculiar behaviour to be illustrated by the sample code
below:
<?php
//Accessing arrays by retrieving elements
via function ArrayName(Index) works, but certainly is neither efficient
nor good style
$excel=new
COM("Excel.Application");
$excel->sheetsinnewworkbook=1;
$excel->Workbooks->Add();
$book=$excel->Workbooks(1);
$sheet=$book->Worksheets(1);
$sheet->Name="Debug-Test";
$book->saveas("C:\\debug.xls");
$book->Close(false);
unset($sheet);
unset($book);
$excel->Workbooks->Close();
$excel->Quit();
unset($excel);
//Accessing
arrays as usual (using the [] operator) works, buts leads to the
application not being able to terminate by itself
$excel=new
COM("Excel.Application");
$excel->sheetsinnewworkbook=1;
$excel->Workbooks->Add();
$excel->Workbooks[1]->Worksheets[1]->Name="Debug-Test";
$excel->Workbooks[1]->saveas("C:\\debug.xls");
$excel->Workbooks[1]->Close(false);
$excel->Workbooks->Close();
$excel->Quit();
unset($excel);
?>
The
sample code performs the same action twice and each time the file is
properly created. Yet for some mysterious reason the instanced excel
process won't terminate once you've accessed an array the way most
programmers (especially those who do a lot of oop in c++) do! Therefore
until the PHP developers become aware of this problem we'll have to use
the inefficient coding style illustrated in the first example.
