php從mysql獲取數據在服務器端產生500錯誤

Question

我在我的網頁中有一個MySQL數據庫和php + js + jquery頁面。

在這個例子中瀏覽器加載一個PHP頁面與此內容：

<script type="text/javascript"> 
    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); 
</script> 
<div id="rss_rcpt"> 
</div> 

peticion_noticia.php

<?php 
    $event=$_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 "<table class='PaperPage'>"; 
    echo "<tr>"; 
    $GLOBALS['normalizeChars'] = array(
     'Á'=>'&Aacute;', 'É'=>'&Eacute;', 'Í'=>'&Iacute;', 'Ó'=>'&Oacute;', 'Ú'=>'&Uacute;', 'Ñ'=>'&Ntilde;', 
     'á'=>'&aacute;', 'é'=>'&eacute;', 'í'=>'&iacute;', 'ó'=>'&oacute;', 'ú'=>'&uacute;', 'ñ'=>'&ntilde;' 
    ); 
    function arregla($toClean){ 
     return strtr($toClean, $GLOBALS['normalizeChars']); 
    } 

    while ($row = mysql_fetch_array($result)) { 
     arregla($row['contenido']); 
     echo "<td class='PaperFechaData' style='width:100px'>" .$row['fecha']. "</td>"; 
     echo "<td class='PaperTitData' style='width:820px'>" .$row['titulo']. "</td>"; 
     echo "</tr><tr>"; 
     echo "<td colspan='2' class='PaperCabData' style='width:920px'>". .$row['cabecera']. "</td>"; 
     echo "</tr><tr>"; 
     echo "<td class='PaperImgData'><img src='".$row['img']."' width='400px' height='400px'></td>"; 
     echo "<td class='PaperTxtData' style='width:520px'>" .$row['contenido']. "</td>"; 
     echo "</tr>"; 
     echo "<tr><td colspan='2'></td></tr>"; 
    } 
    echo "</table>"; 
    mysql_close($con); 
    } else { 
     die(); 
    } 
?> 

我有我的網頁的另一部分相同的代碼結構沒有任何問題，螺母在這種情況下瀏覽器返回HTTP/1.0 500內部服務器錯誤。

Answer 1

echo "<td colspan='2' class='PaperCabData' style='width:920px'>". .$row['cabecera']. "</td>"; 

你在海誓山盟旁邊有兩個點。
