我在我的网页上有一个mysql数据库和php + js + jquery页面。

在这个例子中，浏览器用这个内容加载一个php页面：

function MuestraNoticia(str)

{

if (str=="")

{

document.getElementById("rss_rcpt").innerHTML="";

return;

}

if (window.XMLHttpRequest)

{// code for IE7+, Firefox, Chrome, Opera, Safari

xmlhttp=new XMLHttpRequest();

}

else

{// code for IE6, IE5

xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");

}

xmlhttp.onreadystatechange=function()

{

if (xmlhttp.readyState==4 && xmlhttp.status==200)

{

document.getElementById("rss_rcpt").innerHTML=xmlhttp.responseText;

}

}

xmlhttp.open("GET","auth/peticion_noticia.php?page="+str,true);

xmlhttp.send();

}

MuestraNoticia(1);

$event=$_GET["page"];

if($page == 1){

//allow sessions to be passed so we can see if the user is logged in

session_start();

//connect to the database so we can check, edit, or insert data to our users table

$con = mysql_connect('localhost', 'user', 'pwd') or die(mysql_error());

$db = mysql_select_db('dbname', $con) or die(mysql_error());

$SQL = "SELECT * FROM tablename";

$result = mysql_query($SQL);

echo "

echo "

";

$GLOBALS['normalizeChars'] = array(

'Á'=>'Á', 'É'=>'É', 'Í'=>'Í', 'Ó'=>'Ó', 'Ú'=>'Ú', 'Ñ'=>'Ñ',

'á'=>'á', 'é'=>'é', 'í'=>'í', 'ó'=>'ó', 'ú'=>'ú', 'ñ'=>'ñ'

);

function arregla($toClean){

return strtr($toClean, $GLOBALS['normalizeChars']);

}

while ($row = mysql_fetch_array($result)) {

arregla($row['contenido']);

echo "

" .$row['fecha']. "";

echo "

" .$row['titulo']. "";

echo "

";

echo "

". .$row['cabecera']. "";

echo "

";

echo "

";

echo "

" .$row['contenido']. "";

echo "

";

echo "

";

}

echo "

";

mysql_close($con);

} else {

die();

}

?>我有相同的代码结构，我的网页的另一部分没有任何问题，坚果在这种情况下，浏览器返回HTTP / 1.0 500内部服务器错误。
