如何返回pdf对象而不是使用fpdf保存

Question

I need to create a pdf file and send with a POST request to a server. For creating pdf, the code is very simple

require('fpdf.php');
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output("mypdf.pdf");

For POSTing, I read the pdf file by

$file_contents = file_get_contents("mypdf.pdf");

Is there a way that I don't have to first write to file and then read back from it? Some way of doing

$file_contents = $pdf->Output();

Answer 1

If I get the question correctly, you want the data stream?

If so, Output() take 2 parameters, name and destination. Sending S as destination parameter will return a string of the pdf data.

so, keeping your code

require('fpdf.php');
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$file_contents = $pdf->Output("mypdf.pdf","S");
