I am a novice in php, please help seniors, thank you~!
I just started to learn php. Because I have a little foundation before and at university, it is relatively quick to get started, but the foundation is still very weak. I am currently watching the video of teacher Han Shunping, but found that many recruitments require LAMP, so I don’t know if there are seniors who can give guidance, learning methods, etc. for the learning of linux. And where can I find more mature php cases suitable for novices, this improvement may be faster. I hope that the seniors who saw Xiaosheng’s problem will not hesitate to guide, Xiaosheng hereby thank you~ Response content: I just started to learn php.

Programmer-Who can write a PHP encryption and decryption function, can customize the encryption and decryption key, thank you
Who can write a PHP encryption and decryption function, can customize the encryption and decryption key, thank you Response content: Who can write a PHP encryption and decryption function, can customize the encryption and decryption key, thank you When I first learned VB in junior high school, I wrote an encrypted function. The general principle (process) is like this: Plaintext Xor Key 1 to get Ciphertext 1Ciphertext 1 character by character into Get ciphertext 2 in hexadecimal ciphertext 2 Xor key 2 get ciphertext 3 //Final ciphertext There are many, many ways of encryption (if you want irreversible, you can use MD5() and other functions to achieve it, or even write one yourself, haha), you can use various tricks Coincidentally, you can find ready-made encryption functions on the Internet, but I still suggest that the owner of the question think of an algorithm by himself. After all, don’t those who engage in the Web generally try not to let people know their encryption algorithms? Write your own proprietary encryption algorithm. Still need to write? Mcrpty You can use the encryption function in Disuse, the code is as follows, very easy to use //copy from here /** * $string plaintext or…
Which hero can explain the principle and application of php caching technology to the younger brother, thank you!
Which hero can explain the principle and application of php caching technology to the younger brother, thank you! Response content: Which hero can systematically explain the principle and application of php caching technology to my younger brother, thank you! Static file cache Extensions such as apc, eAccelerator memcache Wait File cache, the cache database is written to the file Memory cache, APC, eAccelerator (php extension implementation), Memcached, Redis, etc. Database cache, cache data written to the database PHP can use Memcached and Redis for data caching. The principle is to build a Memcached or Redis server first, and then install the Memcached/Redis extension of php. In the PHP code, you can connect to the Memcached/Redis server through the API provided in the extension program, and perform data access on Memcached/Redis . It is the same as installing the mysql extension in PHP to connect to the mysql database.
How does PHP traverse all the urls of the website, please give me an idea, thank you
How does PHP traverse all the urls of the website, please give me an idea, thank you The general crawling process is as follows: First crawl all the links on the homepage of the original site, and extract the links in the HTML source code of the page through regular expressions. To ensure availability, the links to be extracted should include: hyperlinks (a tag), Link tag links, and script src attributes Links, image addresses, etc., which belong to the resource category (such as links of link tags, src of img), the resources should be dumped, and the links should be extracted and stored in an array or database. Crawl the inner pages and resources according to the link library, extract the links of the inner pages, save the resources used in the inner pages, compare them with the link library when crawling the home page, and eliminate the same ones to avoid repeated crawling. Add and save the remaining links to the link library. Repeat the crawl until all the links in the link library are crawled. How does php loop through the following data? This is json data (elements at all levels include array objects, etc.), which need to…

Win7 build php environment specific steps, thank you 1. How to install php in win7? WIN under win7 How to install Pear(php) The method of installing Pear(php) under win7 is as follows: Check whether the go-pear.bat or go-pear.phar file exists in the php installation directory.

Command: php go-pear.phar When installing pear, when the following sentence appears, you can directly press Enter. If you make a mistake at the end, you can enter local here when reinstalling. I don’t know why, because I encountered a direct press enter, but the installation was unsuccessful in the end. . Are you installing a system-wide PEAR or a local copy?(system|local) [system] Configure the pear directory: Here you can enter the corresponding data to change the pear directory location. In other words, there is nothing to change, and I am not very familiar…

How does php extract the parameters in the url in the parameters in the url What you should say is to use the GET method to send the form. The parameters here can be resolved with the array GET[] provided by PHP. For example: To extract this jb_id, you can first declare a variable: $jb_id=$_GET[‘jb_id’]; Note that the variable name here is not unique. The format is: $variable name=$_GET[parameter name]; you can write the code for this example: $jb_id=$_GET[‘jb_id’]; $id=$_GET[‘id’] ;$sj=$_GET[‘sj’]; After execution, the value of $jb_id is: 11111, the…
