統計log日誌並排序的php程式

function topIp($logfile,$length=3){ $handle = fopen($logfile, 'r'); $countip = array();//統計ip if ($handle) { while ($buffer = fgets($handle)) {//逐行讀取檔案 $arr = preg_split('/\t/',$buffer); if(strstr($arr[2],"small")){//小圖 //ip為鍵，出現次數為指 $countip[$arr[1]] = $countip[$arr[1]] ? ++$countip[$arr[1]] : 1; } } fclose($handle); arsort($countip);//ip出現次數倒序 return array_slice($countip,0,$length);//提取 } } $topips = topIp('20121030.log',3); var_dump($topips); ?> 複製代碼 輸出的結果：array(3) { ["192.168.1.110"]=> int(10) ["192.168.1.108"]=> int(8) ["192.168.1.120"]=> int(7) }
