这是代码......我收到500内部服务器错误
任何有关这方面错误的帮助？
我在谷歌搜索但没有回答...也许我搜索错了但无论如何。我希望在这里得到一些帮助:)。
答案 0 :(得分：1)
通过编辑php.ini文件打开错误报告。
在php.ini文件中，您会找到两个设置 - error_reporting和display_errors。您应该将error_reporting设置为E_ALL，将display_errors设置为1。重新启动您的网络服务器，然后重新加载您的网页您现在应该看到更具描述性的错误消息。
请注意，其他答案要求您在运行时启用错误报告，但并非所有错误都在运行时触发。在您的代码运行之前将会触发解析错误（例如，错误的语法），因此错误配置仍将使用php.ini文件中定义的值，仍然会留下空白页。
作为旁注，PHP错误也可能会报告给Web服务器的事件日志（其位置因Web服务器和操作系统而异），即使error_reporting已禁用。
答案 1 :(得分：0)
在第13行的while循环之前，您需要设置$page变量，因此：
$page = "";
while(!feof($scfp)) {
$page .= fgets($scfp, 1000);
}
在while循环中添加st。到未定义的$page，所以你需要先定义它。
答案 2 :(得分：0)
启用错误报告。
error_reporting(E_ALL);
ini_set('display_errors', 'on');
你会得到错误。
