output_add_rewrite_var — Add URL rewriter values
This function adds another name/value pair to the URL rewrite mechanism. The name and value will be added to URLs (as GET parameter) and forms (as hidden input fields) the same way as the session ID when transparent URL rewriting is enabled with session.use_trans_sid. Please note that absolute URLs (http://example.com/..) aren't rewritten.
This functions behavior is controlled by the url_rewriter.tags php.ini parameter.
Note: Calling this function will implicitly start output buffering if it is not active already.
The variable name.
The variable value.
如果成功则返回 TRUE，失败则返回 FALSE。
Example#1 output_add_rewrite_var() example
<?php
output_add_rewrite_var('var', 'value');
// some links
echo '<a href="file.php">link</a>
<a href="http://example.com">link2</a>';
// a form
echo '<form action="script.php" method="post">
<input type="text" name="var2" />
</form>';
print_r(ob_list_handlers());
?>
上例将输出：
<a href="file.php?var=value">link</a> <a href="http://example.com">link2</a> <form action="script.php" method="post"> <input type="hidden" name="var" value="value" /> <input type="text" name="var2" /> </form> Array ( [0] => URL-Rewriter )
