示例 #1 tidy_access_count() example

`<?php
$html ='<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 3.2//EN">

<body>
<p><img src="img.png"></p>
</body></html>';
// select the accessibility check level: 1, 2 or 3
$config = array('accessibility-check' => 3);

$tidy->cleanRepair();
/* Never forget to call this! */
$tidy->diagnose();
echo tidy_access_count($tidy); //5
?>`

### 注释

> 注意:

> Due to the design of the TidyLib, you must call tidy_diagnose() before tidy_access_count() or it will return always `0`. You must also need to enable the `accessibility-check` option.
