How to create an RSS reader using PHP
Jacques Noah published an article on devshed about creating a PHP-based RSS reader in PHP4 with any version of MySQL, with three main tags in the RSS document: Title,link and Description, contain the same information as their name hints.
Jacques lists two snippets of code from an RSS document, including the start and end sections, and explains the steps needed to create a PHP RSS reader.
The first is to extract what the label describes. A typical RSS document would be the following structure:
<RSS>
<channel>
<item>
</item>
</channel>
</RSS>
A label like this that does not contain "/" is the starting tag, and the "/" is the end tag, so the function that extracts the content should match the contents of the lookup " " to get the specific content.
Jacques also discusses how to use the built-in functions provided by PHP to make parsing documents clearer and more convenient. After creating the necessary functions, Jacques extracts the function loop and displays the contents of the XML file. Jacques also showed us how to get content in other ways when the RSS reader was unavailable, he created a database of RSS feeds, used a database to help update RSS files, and provided data sheets and code samples about the database.
