php代码如下

<?php 
function get_naps_bot() 
{ 
$useragent = strtolower($_SERVER['HTTP_USER_AGENT']); 
if (strpos($useragent, 'googlebot') !== false){ 
return 'Google'; 
} 
if (strpos($useragent, 'baiduspider') !== false){ 
return 'Baidu'; 
} 
if (strpos($useragent, 'msnbot') !== false){ 
return 'Bing'; 
} 
if (strpos($useragent, 'slurp') !== false){ 
return 'Yahoo'; 
} 
if (strpos($useragent, 'sosospider') !== false){ 
return 'Soso'; 
} 
if (strpos($useragent, 'sogou spider') !== false){ 
return 'Sogou'; 
} 
if (strpos($useragent, 'yodaobot') !== false){ 
return 'Yodao'; 
} 
return false; 
} 
function nowtime(){ 
$date=date("Y-m-d.G:i:s"); 
return $date; 
} 
$searchbot = get_naps_bot(); 
if ($searchbot) { 
$tlc_thispage = addslashes($_SERVER['HTTP_USER_AGENT']); 
$url=$_SERVER['HTTP_REFERER']; 
$file="3water.com.txt"; 
$time=nowtime(); 
$data=fopen($file,"a"); 
fwrite($data,"Time:$time robot:$searchbot URL:$tlc_thispage\n"); 
fclose($data); 
}
