Feedburner Circulation

Returns a database stored Feedburner Circulation Count in plain text or number format. Reduces the Feedburner API calls by only updating the circulation count hourly and serving a database cached result in between. The account you're attempting to get a "Circulation Count" from must have the awareness API turned on. You can use the function <?php circulation_count( $ids, $default, $echo, $format ); ?> in your theme files. The following is an explanation of the parameters the function excepts.

• @param array $ids an array of Feedburner Feed IDs
• @param int $default your fallback circulation count during a zero result: default 0
• @param bool $echo return or echo: default true (echo)
• @param bool $format return as plain integer or number formatted: default true (number format)

For example, if I was Psdtuts+ and wanted to echo out a circulation count that had a fallback or default circulation count in the unlikely event nothing is stored in the database or there is a weird zero result returned, I would do the follow. <?php circulation_count( 'psdtuts', 15000 ); ?> If I wanted to save the count to a variable as a plain integer that I could add to another count or something similar I would do this. <?php $circulation_count = circulation_count( 'psdtuts', 15000, false, false ); ?> If I wanted to echo a formatted count form an array of $ids with a fallback, I would do this. <?php circulation_count( array('psdtuts', 'nettuts'), 200000 ); ?>
