匹配具有一定範圍的時間值的行

Question

我有一個數組公開了來自rooter cisco命令的輸出的數組show ip bgp summary;這個命令顯示used/active/idle /等。連接在bgp連接。

陣列看起來像：

[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) 

我想在陣列ID（router_name）只含有03:30:00的線來表示，而如果它小於6小時後，我想刪除從其餘陣列。

在我的PHP代碼是這樣的：

$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] : ''; } 
} 

和輸出爲：預計

任何解決方案？

Answer 1

這是如何將匹配線與時間小於6小時：

preg_match_all('/^.*0[0-5]:\d{2}:\d{2}.*$/m', $str, $matches); 

對於每次一個hh:mm:ss圖案，其中的小時組分是0和5（含）之間匹配線。

$matches數組包含匹配的行，或者如果沒有行匹配，則爲空。
