- Most of the functions are fairly easy to use. The most difficult part
- is probably creating your first PDF document. The following
- example should help to get you started. It is developed for PHP 4 and
- creates the file <filename>hello.pdf</filename> with one page.
- It defines some document info field contents, loads the Helvetica-Bold
- font and outputs the text "Hello world! (says PHP)".

- The following example comes with the PDFlib distribution for PHP 5.
- It uses the new exception handling and object encapsulation features
- available in PHP 5. It creates the file <filename>hello.pdf</filename>
- with one page. It defines some document info field contents, loads the
- Helvetica-Bold font and outputs the text "Hello world! (says PHP)".
