How can one handle $_POST variables when using FPDF in PHP?

When using FPDF in PHP, you can handle $_POST variables by first checking if the required variables are set using isset() function. Then, you can assign these variables to local variables and use them in your FPDF code to generate PDF documents based on the form input.

if(isset($_POST['input1']) && isset($_POST['input2'])) {
    $input1 = $_POST['input1'];
    $input2 = $_POST['input2'];

    // FPDF code here using $input1 and $input2
}
