I am looking for a reliable way to check to see if a directory

  • 0

I am looking for a reliable way to check to see if a directory contains a Zend_Search_Lucene index. Currently, the only way I have managed to work this out is to check the contents of an exception returned to me using the following code:

<?php try {     $newIndex = Zend_Search_Lucene::open( $luceneDir ); } catch ( Zend_Search_Lucene_Exception $e ) {     if ( strpos( $e->getMessage( ), 'in the specified directory' ) !== false )     {         $newIndex = Zend_Search_Lucene::create( $luceneDir );     } } ?>

This method is not ideal, and a check of the API did not seem very useful. Does anyone know if there is a simple way to see if $luceneDir contains a Zend_Search_Lucene index?
