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)".
