A basic example of using FPDF is with the following PHP code (you must extract the FPDF package in the folder where the PHP file with the code is located).

If you want just minimal features of PDF creation and want a smaller in size class then try these two PDF generating class libraries: Easily create PDF with PHP. In this PHP Tutorial we will show how to covert PHP in PDF file using fpdf class. You can use our PHP example script to convert HTML to PDF. A list of the most important PHP class script and libraries for generating PDF files, PDF manipulation and HTML to PDF conversion.
MaxSelectedPages Maximum number of pages to be selected. The default is the value 0, meaning that all pages will be selected for output.
A value of 1 will extract the contents of the first page only, which can be useful if your PDF file is large and you're only interested by the contents of the first page. When this number is negative, selection starts from the end of the file : -1 means "extract the last page", -2 means "extract the last two pages", and so on. For certain ranges of values, when displayed on a graphical device, these consecutive characters appear to be separated by one space or more.
Of course, when generating ascii output, we would like to have some equivalent of such spacing.
This is what the MinSpaceWidth property is meant for : insert an ascii space in the generated output whenever the offset found exceeds MinSpaceWidth text units.
This quantity is expressed in thousands of "text units". The PdfToText class considers that if this value is less than , then the string specified by the Separator property needs to be appended to the result before the next group of characters. The ImageAutoSaveFormat property will define the image format to be used when generating the image files. Note that the Images property will be left empty.
This flag has been introduced to save internal memory if you only need to extract images. This is the symptom that the pdf file contains only relative positioning instructions combined with big values of text leading instructions. This may sometimes lead to out-of-order text or strings concatenated in an inappropriate way, but this option is to be preferred if you only need to index contents or focus on performance. This is the default option.
Note that the elements will not be mapped in the output exactly as they appear with Acrobat Reader : elements physically disjoint on the x-axis will be separated by a space by default.
The BlockSeparator property can be used to modify this separator. For example, the following text : this is a sam- ple text using hyphe- nated words that can split over seve- ral lines. If the time taken to process a single file may risk to take more time than the value in seconds defined for this property, a PdfToTextTimeout exception will be thrown before PHP tries to terminate the script execution.
If the time taken to process all PDF files since the start of the script may risk to take more time than the value in seconds defined for this property, a PdfToTextTimeout exception will be thrown before PHP tries to terminate the script execution.
This option is useful if you want to define capture areas. No special processing flags apply. Pages Associative array containing individual page contents. The array key is the page number, starting from 1.
PageSeparator String to be used when building the Text property to separate individual pages. The default value is a newline. Separator A string to be used for separating blocks when a negative offset less than thousands of characters is specified between two sequences of characters specified as an array notation.
This trick is often used when a pdf file contains tabular data. The default value is a space. Subject Subject written in the author information part.
Statistics An associative array that contains the following entries : 'TextSize' : Contains the total size in bytes represented by the Postscript-like instructions that draw the document contents 'OptimizedTextSize' : Not all Postscript-like instructions for drawing page contents are significant ; since the parsing is done in pure PHP, it is very slow.
This entry gives the total size of the data that will be effectively parsed after removing the useless instructions. Text A string containing the whole text extracted from the underlying pdf file. Note that pages are separated with a form feed. Title Document title, as specified in the author information object. Utf8Placeholder When a Unicode character cannot be correctly recognized, the Utf8Placeholder property will be used as a substitution. The string can contain format specifiers recognized by the sprintf function.
The parameter passed to sprintf is the Unicode codepoint that could not be recognized an integer value. For example : "1. Normally, most of these exceptions are thrown only if debug mode is activated. Form data extraction Extracting form data is fairly simple : use the GetFormData method and it will return you an object containing all the field values contained in your PDF file, whether they have been filled or not.
You have two ways to retrieve form data : Either by supplying an XML template, that maps actual form field names to more readable names. It provides additional features such as the ability of grouping field values together Or by relying on the default behavior, which will return the form field names as they are defined in the PDF file. Both methods return a new object inheriting from the PdfToTextFormData class, which mainly contain helper functions that have no interest for the caller.
The derived class returned by the GetFormData method has a set of properties that give you access to the form fields contents.
The examples given in the following sections are based on the file "sample. This is why you may want to spend some time designing a template XML file that maps PDF field names to human-readable ones All of the above have been defined in the template file, and the parent class, PdfToTextFormData, is able to handle any modifications made to any of the properties involved in a grouped property.
Now, this is time to have a look at what is a template. This is described in the next section. Think about order documents in your eCommerce application, coupons for your marketing campaign or just the PDF version from your web page. There are plenty of situations were a dynamic PDF document is a great way to solve problems, too. As a developer, you can use several free PHP classes and there is also the PDFlib library which is a commercial product.
This list is a showcase of the most popular PHP classes and libraries. The project website offers great documentation and also a lot of useful code examples. Even for projects where I have used the FPDF class, it was very easy to make the move to this project.
Like many other classes inside the Zend Framework is the documentation very limited for this class as well. If installed compiled , you can use the PDFlib functions right in your PHP code without the need to include a class file or library. Using these tools you need to create any element for your PDF document.
The following example will show how it works. Note, this is just an example on how to use the FPDI class. This feature is useful if you like to generate a PDF version from your website dynamically. The following two projects are the most important scripts if you talk about available information and frequent updates.
The script is able to render styles from external stylesheets and the style attributes from individual HTML elements. You can embed fonts, import pages, order them, etc. Hello Nick, thanks for sharing, I see a lot of functions for the PDF creation also an import function.
Personaly i use wkhtmltopdf and sometime wkhtmltoimage based on webkit, this GNU project provide a simple binary. Thanks for sharing Jeremy, there are many html2pdf conversion tools.
I mentioned only those two because they are more or less PHP scripts. You build a PDF from the scratch or you add data to existing ones.
Or do you do this?
The spacing is done with the line height. You have to do some math to figure out what you want. The line height is the entire height of the line, which means the lines are up against each other. That means whatever you set for the line height is spacing between the letters, as well! With these skills in mind, you should be able to do whatever you want to a PDF. For even more functionality, there is a Scripts section, but of course there is always the PDFlib library which provides all kinds of specialization.
FPDF is a highly documented library though, and it's really simple to use.
