Question

我正在尝试从apache日志文件中获取ip地址并计算唯一的ip

这个apache日志文件有22.22.22.22多10次而125.245.25.25不超过10次

我试图在Apache日志文件

中只获得10次以上的ip

我的PHP代码

<?php 
    $iplist_file="/home/domain/public_html/iplist.txt";

    $iplist_file=file_get_contents($iplist_file);

    preg_match_all('/\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}/',$iplist_file,$a);

    $count = count($a[0]);
    echo "<b>Number of ip</b> = " .$count."<p>";
?>

要从日志中获取所有IP，您可以使用这个非常相似的正则表达式：

preg_match_all('/^(?P<ip>\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})/m', $iplist_content, $matches);

标记m用于多行模式（http://php.net/manual/en/reference.pcre.pattern.modifiers.php），?P<ip>用于命名捕获组 - 而不是$matches[1]我有$matches['ip']（它不是必要）。

正如我所说，在$matches['ip']中，您拥有在日志中创建的所有IP。为了计算它们你可以使用简单循环，或者你可以使用fnc array_count_values。

当我们将这些全部放在一起时，我们得到了这个：

<?php

$iplist_file = "/home/domain/public_html/iplist.txt";
$iplist_content = file_get_contents($iplist_file);

preg_match_all('/^(?P<ip>\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})/m', $iplist_content, $matches);

foreach (array_count_values($matches['ip']) as $ip => $count) {
    print $ip . ': ' . $count . '<br>';
}

preg_match_all从apache日志文件中计算ip地址
