php to pdf issue

brad-taylor1978

Im am using the pdflib to build pdf documents on the fly and in testing recieved this error,

Call to undefined function: pdf_open()

I thought I had installed it properly as the phpinfo() displays the pdf section. Why am i still recieving an error that it is an undefined function? this is the pdf section of the phpinfo() display if it will help.

From the manual for [man]pdf_open[/man]:

This function is deprecated, use pdf_new() plus pdf_open_file() instead.

I tried that as I figured I was using an old way of doing this and it wasn't working. Now the error I get is,

Warning: Cannot modify header information - headers already sent by...

for lines 28,29 and 30. This is the code on the lines that are causing the error.
header("Content-type: application/pdf");
header("Content-Length: ".strlen($buffer));
header("Content-Disposition: inline; filename=chairitable_reciept.pdf");

Why is the browser not liking the headers im trying to sent to it?

This is a FAQ. No output of any kind can be sent to the browser before a header() call --- not so much as a newline or tad or whitespace. Check your script.

I have tried moving that line everywhere and the closest I get is with the following code and it just spits out a blank browser page! What gives? Sorry, Im new to this and am being pushed to get it working. Here is my code thus far.

<?
header("Content-type: application/pdf");
header("Content-Length: ".strlen($buffer));
header("Content-Disposition: inline; filename=chairitable_reciept.pdf");

//start the pdf
$pdf = PDF_new();
PDF_open_file($pdf);

//set up some stuff
PDF_set_info($pdf, "author", "Brad Taylor");

PDF_set_info($pdf, "title", "testing pdf");

PDF_set_info($pdf, "creator", "Brad Taylor");

PDF_set_info($pdf, "subject", "testing pdf");

//set page size
PDF_begin_page($pdf, 450, 700);
$font = PDF_findfont($pdf, "Helvetica-Bold", "winansi",0);
PDF_setfont($pdf, $font, 12);
PDF_show_xy($pdf, "Hello, this is a test of php to pdf", 5, 225);

//end the document
PDF_end_page($pdf);
PDF_close($pdf);

$buffer = PDF_get_buffer($pdf);
echo $buffer;

PDF_delete($pdf);
?>

any help with the code above would save me an ear full!! 😃
