PHP Resource Corner: March 2021

This is another php pdf export feature tutorials, I will create simple PHP script to fetch data from MySQL and create pdf file using php. We will use third party PHP FPDF library. The FPDF is very awesome PHP class to generate PDF using PHP from MySQL database.This is open source php library to generate pdf file using PHP.

PDF is very common and popular file format to read, view and write documents.PDF format is independent of application software, hardware, and operating systems.

FPDF Has Following Main Features

Choice of measure unit, page format and margins.
Page header and footer management.
Automatic page and line break with text justification
Image support (JPEG, PNG and GIF).
Colors
Links
TrueType, Type1 and encoding support
Page compression

We Will Follow Following Steps To Generate PDF

Download the FPDF library from fpdf.org
We will fetch data from MySQL database into the page.
We will use FPDF libs function to generate pdf file with header and footer.

Step 1: We will create employee table into MySQL database.

--
-- Table structure for table `employee`
--
 
CREATE TABLE IF NOT EXISTS `employee` (
  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT 'primary key',
  `employee_name` varchar(255) NOT NULL COMMENT 'employee name',
  `employee_salary` double NOT NULL COMMENT 'employee salary',
  `employee_age` int(11) NOT NULL COMMENT 'employee age',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 COMMENT='datatable demo table' AUTO_INCREMENT=64 ;

We will generate some sample data and insert into employee table.

--
-- Dumping data for table `employee`
--
 
INSERT INTO `employee` (`id`, `employee_name`, `employee_salary`, `employee_age`) VALUES
(1, 'Tiger Nixon', 320800, 61),
(2, 'Garrett Winters', 170750, 63),
(3, 'Ashton Cox', 86000, 66),
(4, 'Cedric Kelly', 433060, 22),
(5, 'Airi Satou', 162700, 33),
(6, 'Brielle Williamson', 372000, 61),
(7, 'Herrod Chandler', 137500, 59),
(8, 'Rhona Davidson', 327900, 55),
(9, 'Colleen Hurst', 205500, 39),
(10, 'Sonya Frost', 103600, 23),
(11, 'Jena Gaines', 90560, 30),
(12, 'Quinn Flynn', 342000, 22),
(13, 'Charde Marshall', 470600, 36),
(14, 'Haley Kennedy', 313500, 43),
(15, 'Tatyana Fitzpatrick', 385750, 19),
(16, 'Michael Silva', 198500, 66);

Step 2: Let’s connect MySQL database with PHP. We will create connection.php file and add below code.

Class dbObj{
/* Database connection start */
var $dbhost = "localhost";
var $username = "root";
var $password = "";
var $dbname = "test";
var $conn;
function getConnstring() {
$con = mysqli_connect($this->dbhost, $this->username, $this->password, $this->dbname) or die("Connection failed: " . mysqli_connect_error());
 
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
} else {
$this->conn = $con;
}
return $this->conn;
}
}

Above file is used to connect and select MySQL database using PHP. You need to change $dbhost, $username, $password, and $dbname variable’s value with your database credentials.

Step 3: We will create generate_pdf.php file and add below code.

<?php
//include connection file 
include_once("connection.php");
include_once('libs/fpdf.php');
 
class PDF extends FPDF
{
// Page header
function Header()
{
    // Logo
    $this->Image('logo.png',10,-1,70);
    $this->SetFont('Arial','B',13);
    // Move to the right
    $this->Cell(80);
    // Title
    $this->Cell(80,10,'Employee List',1,0,'C');
    // Line break
    $this->Ln(20);
}
 
// Page footer
function Footer()
{
    // Position at 1.5 cm from bottom
    $this->SetY(-15);
    // Arial italic 8
    $this->SetFont('Arial','I',8);
    // Page number
    $this->Cell(0,10,'Page '.$this->PageNo().'/{nb}',0,0,'C');
}
}
 
$db = new dbObj();
$connString =  $db->getConnstring();
$display_heading = array('id'=>'ID', 'employee_name'=> 'Name', 'employee_age'=> 'Age','employee_salary'=> 'Salary',);
 
$result = mysqli_query($connString, "SELECT id, employee_name, employee_age, employee_salary FROM employee") or die("database error:". mysqli_error($connString));
$header = mysqli_query($connString, "SHOW columns FROM employee");
 
$pdf = new PDF();
//header
$pdf->AddPage();
//foter page
$pdf->AliasNbPages();
$pdf->SetFont('Arial','B',12);
foreach($header as $heading) {
$pdf->Cell(40,12,$display_heading[$heading['Field']],1);
}
foreach($result as $row) {
$pdf->Ln();
foreach($row as $column)
$pdf->Cell(40,12,$column,1);
}
$pdf->Output();
?>

We will include connection and pdf libs file, for customization of header and footer of pdf files, we will override header and footer methods and define our css design.

Step 4: We will create index.php file and added below code.

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Simple Example of PDF file using PHP and MySQL</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap-theme.min.css">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css"/>
</head>
<body>
<div class="container" style="padding-top:50px">
<h2>Generate PDF file from MySQL Using PHP</h2>
<form class="form-inline" method="post" action="generate_pdf.php">
<button type="submit" id="pdf" name="generate_pdf" class="btn btn-primary"><i class="fa fa-pdf"" aria-hidden="true"></i>
Generate PDF</button>
</form>
</fieldset>
</div>
</body>
</html>

We have added HTML form tag and define action value generate_pdf.php file.

Conclusion:

We have generated pdf file using php and MySQL database, You can generate pdf using other database as well.You just need to create connection with other type database.
