Are there any specific considerations to keep in mind when using truetype fonts in PDF documents generated with FPDF in PHP?

When using TrueType fonts in PDF documents generated with FPDF in PHP, it's important to make sure that the font files are accessible to the FPDF library. You can do this by either placing the font files in the FPDF font directory or specifying the font file path in the FPDF constructor. Additionally, make sure to correctly specify the font name and style when adding text to the PDF document.

// Specify the font file path in the FPDF constructor
require('fpdf.php');

$pdf = new FPDF();
$pdf->AddFont('Arial', '', 'arial.ttf');

$pdf->SetFont('Arial', '', 12);
$pdf->Cell(0, 10, 'Hello World!', 0, 1);

$pdf->Output();
