output_reset_rewrite_vars — Reset URL rewriter values
This function resets the URL rewriter and removes all rewrite variables previously set by the output_add_rewrite_var() function or the session mechanism (if session.use_trans_sid was set on session_start()).
Returns TRUE on success or FALSE on failure.
Example #1 output_reset_rewrite_vars() example
<?php
session_start();
output_add_rewrite_var('var', 'value');
echo '<a href="file.php">link</a>';
ob_flush();
output_reset_rewrite_vars();
echo '<a href="file.php">link</a>';
?>
The above example will output:
<a href="file.php?PHPSESSID=xxx&var=value">link</a> <a href="file.php">link</a>
Example #1 to work, you need
