<?php $datasets = array( 'an index containing "index.php" and the delimiter' => array( 'permalink_structure' => '/index.php', 'index' => 'index.php#', ), 'an index not containing "index.php" and the delimiter' => array( 'permalink_structure' => '/index.php', 'index' => 'somefile.php#', ), ); foreach ( $datasets as $name => $data ) { $result = preg_match( '#^/*' . preg_quote( $data['index'], '#' ) .
