Generate RSS feeds for your website
RSS newsfeeds and product feeds provide a variety of opportunities for increasing traffic to your website. Publishing your own feed is a great way to cut through the clutter of email spam and get your message directly to your target market. Interested parties can subscribe your RSS channel using common Email clients like Outlook. There are also many RSS readers available for Iphones or other smart phones.
RSS slowly becomes one of the important online marketing / SEO tasks.
Provided you already have an online product catalogue. Here is simple PHP code to use to generate a RSS feed:
PHP: | <?php |
| function xmlentities($str) |
| { |
| $xml = array('"','&','&','<','>',' ','¡','¢','£','¤','¥','¦','§','¨','©','ª','«','¬','­','®','¯','°','±','²','³','´','µ','¶','·','¸','¹','º','»','¼','½','¾','¿','À','Á','Â','Ã','Ä','Å','Æ','Ç','È','É','Ê','Ë','Ì','Í','Î','Ï','Ð','Ñ','Ò','Ó','Ô','Õ','Ö','×','Ø','Ù','Ú','Û','Ü','Ý','Þ','ß','à','á','â','ã','ä','å','æ','ç','è','é','ê','ë','ì','í','î','ï','ð','ñ','ò','ó','ô','õ','ö','÷','ø','ù','ú','û','ü','ý','þ','ÿ'); |
| $html = array('"','&','&','<','>',' ','¡','¢','£','¤','¥','¦','§','¨','©','ª','«','¬','­','®','¯','°','±','²','³','´','µ','¶','·','¸','¹','º','»','¼','½','¾','¿','À','Á','Â','Ã','Ä','Å','Æ','Ç','È','É','Ê','Ë','Ì','Í','Î','Ï','Ð','Ñ','Ò','Ó','Ô','Õ','Ö','×','Ø','Ù','Ú','Û','Ü','Ý','Þ','ß','à','á','â','ã','ä','å','æ','ç','è','é','ê','ë','ì','í','î','ï','ð','ñ','ò','ó','ô','õ','ö','÷','ø','ù','ú','û','ü','ý','þ','ÿ'); |
| |
| $str = str_replace($html,$xml,$str); |
| |
| return $str; |
| } |
| |
| $pro = DB_DataObject::factory('Product'); |
| $pro->find(); |
| $xml ='<rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:admin="http://webns.net/mvcb/" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:content="http://purl.org/rss/1.0/modules/content/"> |

To test it, you can type in the URL to the php file in your IE to validate the XML.
You can use a RSS viewer to view the data of your deed:

Making a disk image from a SD Card
I have searched a little Windows program to make a Disk Image from a Phone Micro SD card but couldn’t find one. Therefore I have to put the Micro-SD card into a USB card reader and plug it to a Linux Box.
To make a disk image:
Code: | dd if=/dev/sdb1 of=image.img |
Now if you have a larger SD card and you want to upgrade, swap the card, and run
Code: | dd if=image.img of=/dev/sdb1 |
You need you use the dmesg to find out what’s the device number of your SD Card.
