刷新用于IP黑名单检查的PHP脚本
[英]Flush a PHP script for IP Blacklist Check
问题描述
我有这个用PHP编写的函数
<?php

function flush_buffers(){
ob_end_flush();
flush();
ob_start();
}
function dnsbllookup($ip)
{
$dnsbl_lookup=array(

$AllCount = count($dnsbl_lookup);
$BadCount = 0;
if($ip)
{
$reverse_ip = implode(".", array_reverse(explode(".", $ip)));
foreach($dnsbl_lookup as $host)
{
if(checkdnsrr($reverse_ip.".".$host.".", "A"))
{
echo "<span color='#339933'>Listed on ".$reverse_ip.'.'.$host."!</span><br/>";
flush_buffers();
$BadCount++;
}
else
{
echo "Not listed on ".$reverse_ip.'.'.$host."!<br/>";
flush_buffers();
}
}
}
else
{
echo "Empty ip!<br/>";
flush_buffers();
}
echo "This ip has ".$BadCount." bad listings of ".$AllCount."!<br/>";
flush_buffers();
}
if(preg_match("/^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\z/",@$_GET['ip']) == true)
{
dnsbllookup($_GET['ip']);
}
?>
如果列在某些黑名单上，它会检查IP
http://127.0.0.1/check4_html.php?ip=123.123.123.123
Not listed on 123.123.123.123.access.redhawk.org!
Not listed on 123.123.123.123.b.barracudacentral.org!
Not listed on 123.123.123.123.bl.csma.biz!
Not listed on 123.123.123.123.bl.emailbasura.org!
我有一点问题，我想每次检查时刷新输出，我该怎么办？
当脚本运行时发生的第一件事，我等待20秒，然后弹出20个检查，然后每秒1次，为什么会这样？
任何帮助，将不胜感激。

这个概念对我有用:)
ini_set('output_buffering','on');
ini_set('zlib.output_compression', 0);
ini_set('implicit_flush',1);
ob_implicit_flush();
echo ("<html><head><head><body>");
for($i=0;$i<20;$i++) {
echo $i;
echo str_repeat(" ", 500);
ob_flush();
flush();
sleep(1);
}

flush()似乎不是“output buffering”（ob）的一部分。使用ob_flush() 。 如果使用正确的函数，也不需要ob_end()和ob_start() 。 :)
void ob_flush（void）
此函数将发送输出缓冲区的内容（如果有）。 如果要进一步处理缓冲区的内容，则必须在ob_flush（）之前调用ob_get_contents（），因为在调用ob_flush（）之后将丢弃缓冲区内容。
此函数不会像ob_end_flush（）那样破坏输出缓冲区。
