net::ERR_CONNECTION_RESET从php请求HTML内容时出错

问题

当向PHP脚本发送请求时，如果内容大小适中，我会收到net:：ERR_CONNECTION_RESET。这个脚本在我所有的小文件上都能很好地工作，但在我的大文件上却出现了这个错误。

PHP脚本

<?php
include('Parsedown.php');
function update($url){
        set_time_limit(0);
        $prefix="/doc/";
        $Parsedown = new Parsedown();
        $body = file_get_contents(str_replace($prefix, "", $url, $count));
        $content = $Parsedown->text($body);
        echo $content;
}
if (isset($_REQUEST['action'])) {
   switch ($_REQUEST['action']) {
    case 'update':
        $path = $_REQUEST['path'];
        update($path);
    break;
 }
}
?>

我在本地机器上使用WAMP，我的PHP错误日志中没有错误。

非常感谢您的帮助。
