我有一个数组暴露了rooter cisco命令show ip bgp summary的输出;此命令显示used / active / idle / etc.连接bgp连接。
数组看起来像：
[router_name] =>
8.8.8.8 4 54332 0 0 0 0 0 never Active
4.4.4.4 4 14432 0 0 0 0 0 never Active
1.1.1.1 4 53222 0 0 0 0 0 never Active
3.2.54.3 4 64323 9743 9236 0 0 0 3d14h Idle (Admin)
60.34.22.56 4 99999 8434 9214 0 0 0 3d14h Idle (Admin)
43.22.55.3 4 66789 5057 4980 0 0 0 03:30:00 Idle (Admin)
我想在数组ID（router_name）中显示包含03:30:00的行，如果它小于6小时，我想从数组中删除其余部分。
我的php中的代码是这样的：
$bgp_routers = "/path/to/a/file/that/contains/the/router/list";
$routers_list = array_filter(explode("\n",file_get_contents($bgp_routers)),'strlen');
foreach ($routers_list as $k=>$v) {
$bgp_out[$v]=array_filter(explode('#',shell_exec("$bgp_expect $v")),'strlen');
$bgp_out[$v] = $bgp_out[$v][2];
}
foreach ($bgp_out as $k=>$v){
$bgp_out2[$k] = array_filter(explode("\n",preg_replace(array('/sh ip b s \| i Active\|Idle/'),'',$v)),'strlen');
array_pop($bgp_out2[$k]);
unset($bgp_out2[$k][0]);
}
foreach ($bgp_out2 as $k=>$v){
$count = count($v);
for ($i=1;$i<=$count;$i++) { $bgp1[$k][$i] = (preg_match('/(\s+|.*):(\s+|.*)/',$v[$i])) ? $v[$i] : ''; }
}
输出：
$ bgp_out：

任何解决方案？
答案 0 :(得分：1)
这就是如何匹配一条时间少于6小时的行：
preg_match_all('/^.*0[0-5]:\d{2}:\d{2}.*$/m', $str, $matches);
对于每一行，它匹配hh:mm:ss模式，其中小时组件介于0和5之间。
$matches数组包含匹配的行，如果没有匹配的行，则为空。
