In today's information age, the transmission and exchange of information have extremely convenient and efficient means. Network and digital technologies enable high-quality presentation and delivery of information, both in content and form. However, in information transmission, sometimes traditional text, picture and other formats cannot express the information completely and accurately. At this time, the PDF format appeared. It has good communication adaptability and stability, and is especially suitable for online reading and cross-platform reading. In actual work and life, we sometimes need to convert documents in PHP/HTML format into documents in PDF format to meet more needs.

Generally, third-party components are used to convert PHP/HTML into PDF format documents, such as wkhtmltopdf, which can be implemented through the command line; it can also be implemented using PHP code. Here is an introduction to how to implement third-party components.

First, you need to download and install the wkhtmltopdf tool. After installation, there will be corresponding command line operations in the command line. We need to convert html to pdf with the following command:

wkhtmltopdf input.html output .pdf

Among them, input.html is the name of the HTML file to be converted, and output.pdf is the name of the PDF file output after conversion.

In addition to the above methods, you can also use PHP code to convert PHP/HTML into PDF format documents. Generally, ready-made PDF generation libraries are used, such as: FPDF, TCPDF, DOMPDF, mPDF, etc.

Take FPDF as an example:

First, you need to introduce the FPDF class library (download address: http://www.fpdf.org/):

require_once('fpdf .php');

Then, create a PDF document object:

$pdf = new FPDF();

Set PDF document properties:

$pdf->SetFont('Arial','',14);
$pdf->SetMargins(10, 10, 10);
$pdf->AddPage();

Finally, add the HTML content to the PDF document:

$pdf->WriteHTML($html);

where $html is the HTML string that needs to be converted.

Finally, save the PDF file:

$pdf->Output('output.pdf','F');

Among them, $output is the output PDF file name.

In summary, converting PHP/HTML format into PDF format can be easily achieved using third-party components or class libraries. The specific solution needs to be selected based on actual needs. The PDF format has strong applicability and stability in information transmission. It not only improves the effect of information expression, but also meets the needs of information security. It is very worthy of practice and promotion.
