The Meat of the Code - MySQLIn this article we are going to discuss how to create a PHP-based RSS reader. It would be helpful if you know something about XML, but not really necessary. RSS documents have three main tags: Title, Link and Description. And they all do exactly what their names suggest. I will go into detail about these tags in my second article dealing with “building an RSS file.” For now, we will only focus on the “reading” part of the article.

Now that we have created the required functions, let's continue with the meat of the code: function parsefile($RSSfile){ // Create an xml parser $xmlParser = xml_parser_create(); // Set up element handler xml_set_element_handler( $xmlParser, "startTag", "endTag" );
// Set up character handler xml_set_character_data_handler( $xmlParser, "TxtTag" ); // Open connection to RSS XML file for parsing. $fp = fopen( $RSSfile,"r" ) or die( "Cannot read RSS data file." );
// Parse XML data from RSS file. while( $data = fread( $fp, 4096 ) ) { xml_parse( $xmlParser, $data, feof( $fp ) );
}
// Close file open handler fclose( $fp ); // Free xml parser from memory xml_parser_free( $xmlParser ); } The above function calls both the startTag/endTag functions to loop through the XML file and displays the contents.
