Question

当我使用php请求$.ajax文件时遇到此问题，它总是返回500服务器错误，但仅当我将文件上传到服务器时。我在Windows 8.1上使用XAMPP，在localhost中运行完美。

我已尝试直接访问php文件的网址，同时也给出了同样的错误。

Ajax ：

function get_blog(reload_list){
    var $titulo, $texto, $response, $post, $post_list;
    var parameters = window.location.search;
    $.ajax({
        method: 'get',
        url: '/php/blog.php' + parameters,
        success: function(data){
            if(data == "404"){
                $("#blog").html("404 El articulo que buscas no existe");
            } else {
                $response = data;
                $post_list = $response.post_list;
                $titulo = $response.post.titulo;
                $texto =  $response.post.texto;
                $("title#blog_title").html("IBR - " + $titulo);
                $("h3#blog_title").html($titulo);
                $("#blog_text").html($texto);

                if(reload_list){
                    for(i=0; i<=$post_list.length; i++){
                        $("#post_list").append($post_list[i]);
                    }
                }
            }
        }
    });

PHP ：

<?php
error_reporting(E_ALL);
ini_set('display_errors' 1); 

$l =  mysql_connect ( "localhost" , "myserver" , "mypass" ) or die("Error connecting:<BR><BR>".mysql_error());

mysql_select_db( "mydb" ) or die("Error getting db:<BR><BR>".mysql_error()); 
if(!isset($_GET['post_id'])) {
    $query = mysql_query("SELECT * FROM mytable ORDER BY id DESC LIMIT 1") or die(mysql_error());
    $row = mysql_fetch_array($query);
    $id = stripslashes($row['id']); 
    $titulo = stripslashes($row['titulo']); 
    $texto = stripslashes($row['texto']); 

    $post = [
            'id' => $id,
            'titulo' => $titulo,
            'texto' => $texto
    ];

}else{
    // echo $_GET['post_id'];
    $post_id = $_GET['post_id'];
    $query = mysql_query("SELECT * FROM mytable WHERE id=$post_id ORDER BY id DESC LIMIT 1") or die(mysql_error());
    $row = mysql_fetch_array($query);
    if(empty($row)){
        die("404");
    }
    $id = stripslashes($row['id']); 
    $titulo = stripslashes($row['titulo']); 
    $texto = stripslashes($row['texto']); 


    $post = [
            'id' => $id,
            'titulo' => $titulo,
            'texto' => $texto
    ];
}


$query = mysql_query("SELECT * FROM mytable ORDER BY id DESC") or die(mysql_error());
while ($row = mysql_fetch_array($query) )
{

    $id = stripslashes($row['id']); 
    $titulo = stripslashes($row['titulo']); 

    $li = '<a class="text_decoration post_list_item" href="devocional.html?post_id='.$id.'"><li>'.$titulo.'</li></a>';

    $post_list[]= $li;
}

$response = [
    'post' => $post,
    'post_list' => $post_list
];

$json_response = json_encode($response);
print_r($json_response);
?>

实际上我无法访问error_log。还尝试通过以下方式查看错误：

error_reporting(E_ALL);
ini_set('display_errors' 1);

但浏览器只显示空白页面。我也使用PHP SDK在Facebook API调用上遇到同样的问题。我真的不知道该怎么办。感谢您提前帮助。

PHP并不支持您正在使用的速记数组，直到5.4。 http://php.net/manual/en/migration54.new-features.php，http://php.net/manual/en/language.types.array.php

这是您的更新代码，该代码可以正常工作并与5.6兼容。

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1); 

$l =  mysql_connect ( "localhost" , "myserver" , "mypass" ) or die("Error connecting:<BR><BR>".mysql_error());

mysql_select_db( "mydb" ) or die("Error getting db:<BR><BR>".mysql_error()); 
if(!isset($_GET['post_id'])) {
    $query = mysql_query("SELECT * FROM mytable ORDER BY id DESC LIMIT 1") or die(mysql_error());
    $row = mysql_fetch_array($query);
    $id = stripslashes($row['id']); 
    $titulo = stripslashes($row['titulo']); 
    $texto = stripslashes($row['texto']); 

    $post = array(
            'id' => $id,
            'titulo' => $titulo,
            'texto' => $texto
    );

}else{
    // echo $_GET['post_id'];
    $post_id = $_GET['post_id'];
    $query = mysql_query("SELECT * FROM mytable WHERE id=$post_id ORDER BY id DESC LIMIT 1") or die(mysql_error());
    $row = mysql_fetch_array($query);
    if(empty($row)){
        die("404");
    }
    $id = stripslashes($row['id']); 
    $titulo = stripslashes($row['titulo']); 
    $texto = stripslashes($row['texto']); 


    $post = array(
            'id' => $id,
            'titulo' => $titulo,
            'texto' => $texto
    );
}


$query = mysql_query("SELECT * FROM mytable ORDER BY id DESC") or die(mysql_error());
while ($row = mysql_fetch_array($query) )
{

    $id = stripslashes($row['id']); 
    $titulo = stripslashes($row['titulo']); 

    $li = '<a class="text_decoration post_list_item" href="devocional.html?post_id='.$id.'"><li>'.$titulo.'</li></a>';

    $post_list[]= $li;
}

$response = array(
    'post' => $post,
    'post_list' => $post_list
);

$json_response = json_encode($response);
print_r($json_response);
?>

此外，这里的强制性说明......

将SQL驱动程序从mysql_更改为mysqli或PDO。
将您的用户输入与您的查询分开或在至少使用mysql_real_escape_string（该函数名称可能是颠倒了）。您目前对SQL注入开放。
