Parse error: syntax error, unexpected $end in script.php on line xx
调试了一会后发现产生错误的行是文件中间某行

//$str .= "?>\n";

想起来了 PHP 解释器允许的结尾标记那行还可以用单行注释，即 //$str .= "?>\n"; 被解释成结尾标记前有注释，注释的内容是 //$str .= "，而 ?> 后面的 \n"; 会被解释作 PHP 块外的内容按 HTML 输出出去！结果是给 $str .= "?>\n"; 这行添加 // 成注释后，反而多了个 ?> 的结束标记，造成原来真正的结束标记成了意料之外的（unexpected）了。
解决办法就是直接删掉这一行即可。

PHP 开始和结束标记所在行别写其它东西，是个好习惯。
