What are some common pitfalls when trying to use a truetype font in a PDF document created with FPDF in PHP?

When using a TrueType font in a PDF document created with FPDF in PHP, a common pitfall is not properly embedding the font in the PDF file. To solve this issue, you need to ensure that the font file is embedded in the PDF document using the AddFont method provided by FPDF.

// Include the FPDF library
require('fpdf.php');

// Add the TrueType font file
$fontPath = 'path/to/font.ttf';
$pdf->AddFont('FontName', '', $fontPath);

// Set the font for the document
$pdf->SetFont('FontName', '', 12);

// Add content to the PDF document
$pdf->Cell(0, 10, 'Hello World!', 0, 1);

// Output the PDF
$pdf->Output();
