PHP中文竖排转换实现方法

PHP中文竖排转换程序，文本框输入文字，转换后会竖排文字。

效果图

index.php内容

<?php
include('ccw.inc.php'); 

if (isset($_POST['string'])){
 $ccw = new CCW;
 $converd = $ccw->convert($_POST['string']);
}
?>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<form method="post" charset="utf-8">
 <p><?php echo $converd ?></p>
 <p><textarea name="string" cols="50" rows="10"></textarea></p>
 <p><input type="submit" /></p>
</form>

ccw.inc.php文件内容：

<?php
/**
