我不确定如何读取文件并拉出符合PHP条件的3个IP。我尝试使用爆炸，但这会爆炸所有的空间....我可以得到的任何一种帮助非常感谢：

我尝试使用：
readfile(/var/log/asterisk/messages)
我只是想让$ip附加195.154.53.90
$ip=$search[]
答案 0 :(得分：3)
我可能会后悔这一点，但在这里：
$ip = '195.154.53.90';
$result = preg_grep(preg_quote("/$ip/"), file('/var/log/asterisk/messages'));
print_r($result);
根据评论，找到找到195.154.53.90:5068的位置的任何IP（用单引号括起来）：
preg_match_all("/'(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}):\d+'/",
file_get_contents('/var/log/asterisk/messages'),
$ip);
print_r($ip[1]);
答案 1 :(得分：2)

文本后面的IP：
failed for上面的代码所做的是它首先将您的日志文件拆分为单独的行，将这些行映射到正则表达式匹配的结果，然后过滤掉不包含IP的日志行。
如果您需要以下$lines = explode("\n", file_get_contents("/var/log/asterisk/messages"));
$ips = array_filter(array_map(function($item) {
$matches = [];
if(preg_match($item, "/'(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}):\d+'/")) {
return $matches[1];
}
return false;
}, $lines), function($item) {
return $item !== false;
});
的IP，则需要将正则表达式更改为以下内容：<sip:
