php 数据库连接 编码设置问题

我先在本地运行PHP网站，环境已经搭配好啦，数据库也导进去啦，在IIS 浏览时出现错误，弹出一个提示框，“.$str.”

错误就是这段。有没有大神帮忙看看。

public function show_error($message='',$sql=''){
echo "

";
echo "

错误信息提示:

";
echo "

";
echo '错误原因：'. mysql_error() . "

";
echo "

";
echo "" . $message . "";
echo "

";
echo "

" . $sql . "

";
echo "

";
echo "

";
}

能帮忙看看吗？搞一上午了这个问题。

你先截个图看看，感觉不是你认为的地方

把你那块的代码拿来看看，你那段错误信息没有明显的指出错误的地方

这是数据库连接的那段代码!

你先截个图看看，感觉不是你认为的地方

我点击index.php 的时候它出来的是数据库连接的代码和两个连着弹窗 “.$str.”，弹窗的后面就是我贴上的那段代码其中这块显示红色
public function show_error($message='',$sql=''){
echo "

";
echo "

错误信息提示:

";
echo "

";
echo '错误原因：'. mysql_error() . "

";
echo "

";
echo "" . $message . "";
echo "

";
echo "

" . $sql . "

";
echo "

";
echo "

";

点完 确定 就显示无法找个该页的。

这是PHP配置环境 mysql没有值 跟这个有关系吗？wordpress phpMyAdmin 都装了 这些地方都没有问题。
