嗯，正如标题所说。我正在使用 codeigniter 4，并且一直在尝试添加 Arial 字体以在 Dompdf 中使用它。我尝试将 Airal.ttf、Arial.afm 和 Arial.php 文件添加到 dompdf 文件夹中的“lib/fonts”文件夹中，但它不起作用。也许我错过了什么？我有这个用于测试目的，但它不起作用：
<?php
require 'vendor/autoload.php';
use Dompdf\Dompdf;
use Dompdf\Options;
// Set Dompdf options
$options = new Options();
$options->set('fontDir', 'vendor/dompdf/dompdf/lib/fonts');
$options->set('fontCache', 'vendor/dompdf/dompdf/lib/fonts');
$options->set('defaultFont', 'Arial'); // Make sure this matches the font you registered
// Create Dompdf instance
$dompdf = new Dompdf($options);
// Simple HTML content for testing
$html = '
<html>
<head>
<style>
body {
font-family: Arial;
}
</style>
</head>
<body>
<h1>This is a test PDF using Arial font</h1>
<p>Check if the Arial font appears correctly in the PDF.</p>
</body>
</html>';
$dompdf->loadHtml($html);
$dompdf->setPaper('A4', 'portrait');
$dompdf->render();
// Output the generated PDF to the browser
$dompdf->stream("output.pdf", ["Attachment" => false]);
?>
<?php
require 'vendor/autoload.php';
use Dompdf\Dompdf;
use Dompdf\Options;
// Set Dompdf options
$options = new Options();
$options->set('isHtml5ParserEnabled', true);
$options->set('isPhpEnabled', true); // Enabling PHP inside the HTML (like inline scripts)
//$options->set('fontDir', 'vendor/dompdf/dompdf/lib/fonts');
//$options->set('fontCache', 'vendor/dompdf/dompdf/lib/fonts');
//$options->set('defaultFont', 'Arial'); // Make sure this matches the font you registered
// Create Dompdf instance
$dompdf = new Dompdf($options);
$dompdf->getOptions()->set('fontDir', '/path/to/font/directory');
$dompdf->getOptions()->set('fontCache', '/path/to/font/cache');
// Simple HTML content for testing

$dompdf->loadHtml($html);
$font = 'path/to/font.ttf';
$dompdf->getCanvas()->getFontMetrics($font);
$dompdf->setPaper('A4', 'portrait');
$dompdf->render();
