require __DIR__."/vendor/autoload.php"
use Dompdf\Dompdf ;
$dompdf = new Dompdf;
$dompdf -> loadHTML("Welcome To TalkersCode") ;
$dompdf -> render() ;

Example 2
In this example, we will see another example of taking input form an HTML form to generate a pdf. We will see the code for both the HTML file and the php file.
HTML code
<!DOCTYPE html> <html lang = " en " > <head> <meta charset = " UTF - 8" > <meta http-equiv = " X-UA-Compatible " content = " IE=edge " > <meta name = " viewport " content = " width = device-width , initial-scale = 1.0 " > <title> php generate pdf from html </title> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/water.css@2/out/water.css"> </head> <body> <h1 style=" color : rgb(113, 221, 113) ;"> TALKERSCODE </h1> <h2> php generate pdf from html </h2> <form action="generate-pdf.pdf" method="post"> <label for="name">Name</label> <input type="text" name="name" id="name"> <label for="quantity">Quantity</label> <input type="text" name="quantity" id="quantity"> </form> </body> </html>
- First, we write <! DOCTYPE html> which we used as the instruction to the web browser about what version of HTML file is written in.
- Secondly, the <html> tag is used to indicate the beginning of an HTML document.
- As mentioned above, the <head> tag contains information about the web page. In this tag, a <title> tag is used which helps us to specify a webpage title.
- Both <head> and <title> tags are Paired tags. So, both have </head> and </title> ending tags respectively.
- Thirdly, the <body> tag is used to define the webpage body. All the contents to show on the website are written here.
- <h1> tag used to add heading here and also adding the inline CSS here.
- Creating a form using <form> tag with the action of the pdf file with the method POST.
- Two <input> tag for take the input for user of Name and Quantity.
- Using a external css file to style the form
- Close the HTML tag with </html>
Php code
<?php
require __DIR__."/vendor/autoload.php"
use Dompdf\Dompdf ;
use Dompdf\Options ;
$name = $_POST["name"] ;
$quantity = $_POST["quantity"] ;
$html = '<h1 style="color: pink">Example PDF</h1>' ;
$html.= "name : $name" ;
$html.= "quantity : $quantity" ;
$html.= '<img src = "bird.png">' ;
$options = new Options ;
$options ->setChroot(__DIR__) ;
$dompdf->setPaper("A4", "landscape") ;
$dompdf = new Dompdf($options);
$dompdf -> loadHTML($html) ;
$dompdf -> render() ;
$dompdf-> addInfo("Title", "this is a demo pdf") ;
$dompdf -> stream("demo.pdf", ["attachment" => 0]) ;
$output = $dompdf->output() ;
file_put_contents("file.pdf", $output) ;
?>
- At first <?php tag to write the php.
- Using require to include the DOMPDF library with _DIR_ .
- Use the function to Dompdf\DOMpdf and Dompdf\Options.
- Creating two variable for $name and $quantity with the $_POST method
- $html to add some heading to with some inline CSS.
- $html. To add name and quantity from the user’s input. Also adding an image
- To allow Dompdf to access the image file with any folder create a variable named $options. Using setChroot() with _DIR_.
- We can set the pdf size with setPaper() function. Here we set the size to A4 and landscape.
- now using the render() function
- we also can set the Title of the pdf using addInfo().
- stream() to add the name of the pdf with an attachment of 0.
- To download the pdf include output() function
