Complain about Baidu search, be less rogue and more responsible! , Baidu search is one less
As a programmer, I rarely use Baidu. The same technical problem can be easily found on Google, and Baidu can't find it for a long time. Even if it is found, it is not original. Many of them were originally written by brothers in the blog garden, but the URLs found in the search were not the cnblogs URL. You know, in an online world full of ads and malicious code, it takes a lot of courage to open an unfamiliar website address. Moreover, many times you need to search in English to find the answer, and you can't even count on Baidu.
Since it is rarely used, why do you still complain about BD? Let me start with the sore throat this time. It may be that spring came too suddenly and my body got angry. I went to the hospital and was diagnosed with tonsil inflammation. The doctor prescribed anti-inflammatory drugs and buccal tablets. As soon as I got out of the hospital, I put the buccal tablets in my mouth. After taking 2 tablets, my throat felt really comfortable. When I returned to the dormitory, I turned on my buddy's computer and remembered to read the instructions for this medicine. Since it is produced by "Lunan Pharmaceutical", let's go to the official website first. My buddy has set Baidu as the homepage, input "Lunan Pharmaceutical", baidu, the first page, not found, the second page, not yet. As a result, I found the official website :www.lunan.com.cn in Baidu Encyclopedia.
I thought, let’s look at the situation of other search engines. Switch to google, and the first record in the search results is. Sogou, 360 search is the first one:
If you are a novice who doesn’t know much about computers, you may accidentally go to a phishing website on Baidu.
This reminds me of a friend who does Baidu search optimization. As long as he pays him a certain amount of money, he can guarantee that a certain keyword will be ranked first on Baidu.
Maybe Baidu will say: "Our Baidu spider algorithm is very advanced. It is automatically ranked by computers without manual intervention. Is it because the website is not optimized well?"
"Holy shit, the algorithm was not written by humans. Phishing websites are ranked first, and they are well optimized!"
Someone said: "In China, search is equal to Baidu." What I want to say is: "The greater the ability, the greater the responsibility! As the boss of Chinese search, be less rogue and have more responsibility!".

How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AMIn PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.
