Generating PDF’s is an easy method to make a very nice printable and/or savable version of an article. This could be helpful in a WordPress blog or any articles website. This method utilizes the popular FPDF class.
First of all, I suggest you get the latest FPDF version from here. I suggest creating a directory such as “pdf” on your web hosting space. You will need to place the fpdf.php into that directory, you will only need it.
Let’s make our first “Hello World” example. Place the following in a file called test.php:
<?php require('fpdf.php'); $pdf = new FPDF(); $pdf->AddPage(); $pdf->SetFont('Arial','B',16); $pdf->Cell(40,10,'Hello World!'); $pdf->Output(); ?>
Now let’s see that code line by lineâ€¦
This line includes our FPDF class that we need to create the PDF file.
This line creates a new instance of the FPDF class which will be binded to $pdf
This line tells FPDF to add a new page to the PDF file; obviously we need one page so we will call this function once.
This line tells the FPDF class to change the font to Arial, bold, 16 pt.
This line is just like the “echo” of PHP, the text fields in PDF files are just sort of rectangles with text in them, so we want the width of 40 pt. and a height of 10 pt., the third value is the text to be written in that rectangular box.
Our final line, which pretty much means: “weâ€™re done, show us our PDF!”
That’s a very simple FPDF usage, however, here is a bit of more advanced version of FPDF usage:
<?php require('fpdf.php'); $pdf = new FPDF("L", "mm", "A4"); $pdf->AddPage(); $pdf->SetFont('Arial','BIU',30); $pdf->SetTextColor(0,0,255); $pdf->Cell(60,20,'PDF+PHP Test',1,1,C,0); $pdf->Output(); ?>
Now let’s do a quick review of that more advanced code:
$pdf=new FPDF("L", "mm", "A4");
This will create a new instance but instead will default to creating landscape pages because of the first
P can be used instead to default to portrait pages. The second value is the default measurement unit, a choice of point (
pt), millimeter (
mm), centimeter (
cm) and inch (
in) is given. The last value is the size of the page, the choice of
Legal is given.
Simple function, just add the page, you can tell the function to create either a portrait (
P) or landscape (
L) by giving it as a first value (ex:
This required function again says that we want an Arial, 30 mm in size (because of the default size unit), the
'BIU' simply tells that we want it to be Bold, Italic & Underlined.
This sets the default text color for the text we will be writing, Iâ€™ve chosen blue here, the first value is red (
r), the second is green (
g) & blue (
This makes the so famous rectangle with 60 mm of width & 20 mm of height, we wrote ‘PDF+PHP Test’ and the first
0 means we do not want a border. The
1 next to it means that once itâ€™s done the cell, it will go to the beginning of the next line, if
0 is provided, then it will be to the right of it, if
2 is provided then it will go below. The
C is just the alignment which is center of the text inside the box, possible values are left (
L), center (
C), right (
Output our brand new colorful PDF file!
