RSS PHP generated class, fast read build requires XML file

The RSS 2.0 version of PHP generated class is used in the project.

You can generate an XML file and output it through a function simply by inputting it into the data structure.

Use the time to change several constants into the parameters you need, and then you can output the standard RSS code as described below.

This program uses GBK local environment character set, if your local environment is UTF-8, please modify this code local_charset = ' GBK ';

/* Test Case */$aChannel = array (' title ' = ' Weekly featured ', ' description ' = ' Latest used Car news ', ' link ' = ' http://www.chemao.com.cn/ Baike-gonglue.html '); $o = new Crssbuilder ($aChannel); $aItem = Array (    ' title ' = ' Meet baby, get on the cat net to buy the right polo ',    ' Link ' = ' http://www.chemao.com.cn/baike/cwpolo.html ',    ' description ' = ' I love my husband in college, both of them are northerners. Because the family is suitable for their own employment opportunities are few, after graduating two people came to Hangzhou development. Two years of hard work, last July we finally ended 5 years of love long-distance running, in the West Lake with friends and relatives to witness our love. '    category ' = ' Weekly selection ',    ' utc_timestemp ' =>time ()), $o->additems ($aItem); $aItem = Array (    ' Title ' = ' To meet space needs, buy a second-hand MPV can be OK!

And the arrival of gold nine silver not only make new car concessions more and more big, the price of used cars is also a sharp dive, the price of MPV is "a derogatory and then derogatory", for those who want to start this kind of model, now is the perfect time! Below, we recommend several used car market common popular MPV. '    category ' = ' Weekly selection ',    ' utc_timestemp ' =>time ()); $o->additems ($aItem); Echo $o->getserialize ();

The above describes the RSS PHP generation class, fast-read generation needs XML files, including the entrepreneurial aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
