# output_add_rewrite_var

(PHP 4 >= 4.3.0, PHP 5)

output_add_rewrite_var -- Add URL rewriter values

## Description

bool output_add_rewrite_var ( string name, string value )

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.

> Nota: Calling this function will implicitly start output buffering if it is not active already.

Exemplo 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()); ?>`
O exemplo acima irá imprimir:
    <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
    )
