Title: An effective way to fix Chinese garbled characters in PHP Dompdf
When using PHP Dompdf to generate PDF documents, garbled Chinese characters are a common problem. This problem usually stems from the fact that Dompdf does not support Chinese character sets by default, resulting in Chinese content not being displayed correctly. In order to solve this problem, we need to take some effective ways to fix the Chinese garbled problem of PHP Dompdf.
1. Use custom font files
An effective way to solve the problem of Chinese garbled characters in Dompdf is to use custom Chinese font files. First, we can choose a font file that supports Chinese character sets, such as Microsoft YaHei or Song Dynasty. Next, copy the font files to Dompdf's fonts folder (usually the /dompdf/lib/fonts/ directory). Finally, by setting the font configuration file of Dompdf, specify the use of this custom font file to display Chinese characters.
use DompdfDompdf;
use DompdfOptions;
require 'vendor/autoload.php';
$options = new Options();
$options->set('fontDir', 'path/to/custom/fonts/');
$options->set('defaultFont', 'Arial');
$dompdf = new Dompdf($options);
$html = '<html><head></head><body><p>中文内容</p></body></html>';
$dompdf->loadHtml($html);
$dompdf->render();
$dompdf->stream();In the above code, we specify the path to the font configuration file and set the default font to Arial. In this way, Dompdf will use the specified Chinese font file when rendering PDF, thereby correctly displaying Chinese content.
2. Convert Chinese character encoding
Another way to solve the Chinese garbled problem of Dompdf is to convert Chinese characters into a suitable encoding format, such as UTF-8. When generating HTML content, we can use PHP's mb_convert_encoding function to convert Chinese characters to UTF-8 encoding to ensure that Dompdf can correctly parse and display Chinese content.
use DompdfDompdf;
require 'vendor/autoload.php';
$dompdf = new Dompdf();
$html = '<html><head></head><body><p>' . mb_convert_encoding('中文内容', 'UTF-8', 'auto') . '</p></body></html>';
$dompdf->loadHtml($html);
$dompdf->render();
$dompdf->stream();By converting Chinese character encoding to UTF-8, we can effectively avoid the problem of Chinese garbled characters in Dompdf and ensure that Chinese content is displayed normally in PDF documents.
Summary
An effective way to repair PHP Dompdf Chinese garbled characters can be achieved by using custom font files or converting Chinese character encoding. Choosing the appropriate method and appropriate code examples can make the generated PDF document display Chinese content correctly, improving user experience and readability. I hope the above method will help solve the problem of Chinese garbled characters in Dompdf.
