File Excel: OPEN

[wdb]

Ho copiato da qualche parte questo codice che scrive da PHP un file EXCEL:

<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:{$exapp->Application->value}
" ;
print "Loaded version: {$exapp->Application->version}
";

$wkb=$exapp->Workbooks->add();
#$wkb = $ex->Application->ActiveWorkbook or Die ("Did not open workbook");
print "we opened workbook
";

$exapp->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
";

$file_name="C:\Temp\final14.xls";
if (file_exists($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);
?>

</pre>

Benissimo: funziona alla grande.

Ora pero' domando:

utilizzando la stessa sintassi dell'esempio, come faccio anche a leggere un file Excel, oltre che scriverlo?

E' possibile aprire un file Excel e riempire le sue celle con i dati e poi salvarlo?

Grazie
