output_reset_rewrite_vars — Reset URL rewriter values

### Description

output_reset_rewrite_vars(): bool

This function removes all rewrite variables previously set by the output_add_rewrite_var() function.

### Parameters

This function has no parameters.

### Return Values

Returns `true` on success or `false` on failure.

### Changelog

Version | Description
--- | ---
7.1.0 | Before PHP 7.1.0, rewrite vars set by output_add_rewrite_var() use the same Session module trans sid output buffer. Since PHP 7.1.0, dedicated output buffer is used and output_reset_rewrite_vars() only removes rewrite vars defined by output_add_rewrite_var().

### Examples

Example #1 output_reset_rewrite_vars() example

`<?php
ini_set('url_rewriter.tags', 'a=href');
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?var=value">link</a>
    <a href="file.php">link</a>
