This article mainly introduces PHP code summary for determining whether a visitor is a search engine spider or a common user. There are always one method that suits you, prevent search engine spider from dragging the search engine. 1. recommended method: php judges whether the search engine spider crawlers are manually accessing the Code, from Discuz x3.2
In actual applications, you can determine that the operation is not performed by a search engine.
2. Method 2:
Use PHP to collect spide
registry in quiet modeOK! After the import, restart the machine to solve the TCP/IP filtering problem,Then run the command iisreset/reboot/Timeout: 00 in the "ws restart. Shell"# Use his own IIS service to restart his machine
2nd cases: Use the terminal port-automatically log on to check and use IP: port connection for example: 61.235.153.16: 3457
You can use the LCX port forwarding tool in 3rd cases and 4th cases!First, we need to first upload lcx.exe. Here I have uploaded it!The first and thi
1, recommended a method: PHP Judge search engine Spider crawler or human access code, from Discuz x3.2
The actual application can be judged in this way, directly not the search engine to perform the operation
2. The second method:

Yesterday saw the basic knowledge of Robocode, himself wrote a bot, put on the battlefield on the lack of repeated war repeatedly defeated ... Sad ing.
Bot has a very limited understanding of the surrounding environment. It can know the distance, azimuth, direction, speed and energy level of other robots. However, it does not see the bullets. How can we effectively avoid each other's bullets?

A week ago, I shared an article "Seo diagnosis: finding a website to die through log" and attached two suggestions for improvement. Due to the limitation of objective conditions, the robots shielding method is used at last. First, let's take a look at the spider changes a week later. The total volume of crawlers from the three major spider crawlers decreases sharply, proving that the robots file has taken effect. From the view of the number of visits, total stay time, and total captures on the g
