You've been having lots of problems with these pdf's VssP!

whats the error message you received with the windows machine.

writing to pdf's through php isn't that practical and would take alot of code. and i don't know how off the top of my head.

{
echo $errstr;
}
$old_error_handler=set_error_handler("myErrorHandl er");
//trigger_error("Incorrect page limit", E_USER_ERROR);
//Folder where the temporary files will be uploaded for modifications if(is_uploaded_file($_FILES['file']['tmp_name']))
//Create a new pdf object
$pdf = pdf_new();

//Set the required parameters
pdf_set_parameter($pdf, 'pdiwarning', 'true');
pdf_set_parameter($pdf, 'compatibility','1.5');

//Open an inmemory pdf file
pdf_open_file($pdf,"");

//$pdi = pdf_open_pdi($pdf, "firstfile.pdf", "", 0);
//$page= pdf_open_pdi_page($pdf, $pdi, 1, "");


//Get the file to add the content
//ile='pdffiles/'.$_FILES['file']['name'];
//Actual filename which will be used later to download the modified file
//ilename=$_FILES['file']['name'];
//Get the file to add the content
$file='pdffiles/'.$_FILES['file']['name'];
//Actual filename which will be used later to download the modified file
$filename=$_FILES['file']['name'];

//$file='pdffiles/'."doc.pdf";
//Actual filename which will be used later to download the modified file
//$filename='doc.pdf';


$pdi = pdf_open_pdi($pdf, $file, "", 0);
//$page= pdf_open_pdi_page($pdf, $pdi, 1, "");

// $width = pdf_get_pdi_value($pdf, "width", $pdi, $page, 0);
// $height = pdf_get_pdi_value($pdf, "height", $pdi, $page, 0);


//Gets the content to be added and noof pages in the pdf document
//$content='test test';
//$length=strlen($content);
$content=$_REQUEST['content'];
$length=strlen($content);


$noofpages = pdf_get_pdi_value($pdf, "/Root/Pages/Count", $pdi, 0, 0);


//$noofpages=3;

//Creates a pdi instance for the selected file
//$pdi = pdf_open_pdi($pdf, $file, "", 0);

//Loop for importing the contents of every page
for($i=1;$i<=$noofpages;$i++)
{

//Imports the selected page
$page= pdf_open_pdi_page($pdf, $pdi, $i, "");
//Gets the dimensions of the selected page
$width = pdf_get_pdi_value($pdf, "width", $pdi, $page, 0);
$height = pdf_get_pdi_value($pdf, "height", $pdi, $page, 0);
//Starts a new pdf page
pdf_begin_page($pdf, $width, $height);
// place page from pdi into the pdf file
pdf_place_pdi_page($pdf, $page, 0.0, 0.0, 1.0, 1.0);
// now add text to the first page at the top right corner
if($i==1)
{
$font = pdf_findfont($pdf, "Courier", "host", 0);
pdf_setfont($pdf, $font, 10);
pdf_show_xy($pdf, $content, $width-(($length*6)+10), $height-15);
}
//
pdf_close_pdi_page($pdf, $page);
pdf_end_page($pdf);
}
pdf_close($pdf);

//Send the modified pdf file to the user
