Can anyone please explain the usage of PDF_info_matchbox. I have read the PHP Manual at http://php.net/manual/en/function.pdf-info-matchbox.php but it is not very clear.
float PDF_info_matchbox ( resource $pdfdoc , string $boxname , int $num , string $keyword )
Neither can I understand the meaning of matchbox
Kindly explain the usage of individual parameters if possible.
Examples will be really appreciated
Thanks
