Detailed explanation of the method of recording search engine crawling process in PHP

This time I will bring you a detailed explanation of the php record search index engine crawling process method, what are the precautions for php record search engine crawling process, the following is a practical case, let’s take a look take a look.

The following is the complete code:

//记录搜索引擎爬行记录 $searchbot = get_naps_bot(); 
if ($searchbot) 
{ $tlc_thispage = addslashes($_SERVER['HTTP_USER_AGENT']); 
$url = $_SERVER['HTTP_REFERER']; 
$file = WEB_PATH.'robotslogs.txt'; 
$date = date('Y-m-d H:i:s'); 
$data = fopen($file,'a'); 
fwrite($data,"Time:$date robot:$searchbot URL:$tlc_thispage/r/n"); 
fclose($data);
}

WEB_PATH is the root directory path of define under index.PHP, which means that the robotslogs.txt file is placed in the root directory.

Get the spider crawling record through get_naps_bot(), then process it through addslashes, and store the data in the variable $tlc_thispage.

fopen opens the robotslogs.txt file, writes the data through the function fwrite, and closes it through the function fclose.

Because I felt it was unnecessary, I deleted the code on my website, so there are no examples of the effect.
