One of the biggest advantages of PHP is its easy support for new technologies. the scalability of this language allows developers to easily add new modules, in addition, the support of technical groups all over the world and the support of many extension modules make PHP one of the most functional Web programming languages. Currently, the extension module allows developers to perform IMAP and POP3 operations, dynamically generate images and ShockwaveFlash animations, and perform credit card verification, one of the biggest advantages of sensitive data PHP is its easy support for new technologies. the scalability of this language allows developers to easily add new modules, in addition, the support of technical groups all over the world and the support of many extension modules make PHP the most functional Web programming language.
I. Currently, the extension module allows developers to perform IMAP and POP3 operations, dynamically generate images and Shockwave Flash animations, perform credit card verification, and encrypt and decrypt sensitive data, it can also parse data in XML format. But this is not all. At present, another new module can be bound with PHP, which is the PDFLib extension module, he enables developers to dynamically generate PDF (Adobe Portable Document Format) files. Next let's take a look at how to use this module in PHP.
To enable PHP to operate PDF files, you must first install the PDFLib extension library in your system. if you are using an Lunix system, you can download a compiled PDFLib Library from idea, and then remove the comments of the corresponding lines in the PHP settings file.
Extension = php_cmd.dll
For dynamic loading, refer to the following command:
Dl ("php_cmd.dll ");
In addition, you must have an Adobe Acrobat PDF reader to browse the PDF format. if you do not have one, you can download it from http://www.adobe.com/for free.
Once you have prepared a PDF file, you can create it. The following is a simple example:
Save it as a PHP file and browse it in the browser. PHP will execute the above code, generate a new PDF file, and save it to the specified location.
At present, let's analyze what code we need to use PHP to create a PDF file. There are four steps: 1. create a file handle; 2. Register the font and color of the file; 3, use the functions provided by PDFLib to write text or drawing to the file handle; 4. Save the file.
First, create a PDF file handle. The syntax is as follows:
$ Pdf = pai_new ();
