By playing around with this you'll get a better understanding of what pdf_save and pdf_restore do.

<?php

//Create & Open PDF-Object
$pdf pdf_new();
pdf_open_file($pdf);
pdf_set_info($pdf"Author","Bob Nijman");
pdf_set_info($pdf"Title","Sponsored by www.nijman.de");
pdf_set_info($pdf"Creator""See Author");
pdf_set_info($pdf"Subject""pdf_restore");
pdf_begin_page($pdf300300);


/*
By encapsulating the changes we make to the coordinate system
(pdf_translate() and pdf_rotate()) between pdf_save() and pdf_restore
we give these changes only local scope.
*/

/*
SMALL RECTANGLE
*/

pdf_save($pdf);
//move the origin of the coordinate system to (100,100)
pdf_translate($pdf100100);
//Rotate the coordinate system by 45 degrees.
pdf_rotate($pdf45);
//Draw a samll rectangle
pdf_rect($pdf002020);
pdf_stroke($pdf);
//Restore the graphics state to the way it was
//before we started to translate and rotate
pdf_restore($pdf);


/*
LARGER RECTANGLE
*/

pdf_save($pdf);
//move the origin of the coordinate system to (10,20)
pdf_translate($pdf1020);
//Rotate the coordinate system by 15 degrees.
pdf_rotate($pdf15);
//Draw a larger rectangle
pdf_rect($pdf004040);
pdf_stroke($pdf);
//Restore the graphics state to the way it was
//before we started to translate and rotate
pdf_restore($pdf);



//close it up
pdf_end_page($pdf);
