我有一个HTML页面，它将一个PHP文件加载到一个DIV中，如下所示：

<!doctype html>

DIV被命名为content

PHP文件在DIV中有一个搜索表单，PHP脚本执行数据库搜索，并将检索到的数据回送到同一页面上的DIV中。如果我不将PHP文件加载到主HTML页面上的DIV中，这就可以了。当我在DIV中加载PHP文件时，PHP文件中的表单会正确地显示在主页上的DIV中，但是搜索结果不会。它们根本不显示，DIV只显示原始HTML页面。不知道为什么会这样

以下是PHP文件的代码：

。我没有发布所有代码。echo语句在PHP代码中的位置更靠下。正如我所说，如果我只运行PHP文件，它就可以正常工作。如果我将其加载到主HTML页面的DIV中，则只加载PHP文件中的表单，当我进行搜索时，不会看到结果。我希望结果显示在PHP加载到我的HTML主页上的同一个DIV中。这不是因为您有一个
