PHP routing implementation principle, please give me some advice
After using the framework for a while, I suddenly realized that it seems that the core of the MVC framework is routing. Can you please enlighten me on the specific principles. For example, TP5 routing is very powerful, but the source code has basically no comments. After reading it for 2 hours, I still don’t understand the whole process. How it is. All I can do now is the pathinfo step. I can’t understand the various rule routing and regular routing that follow. I hope you can give me an implementation process, or a specific demo, or tutorial, which can be related. Books are also available O(∩_∩)O Thank you!

Crawl image information, but lazy loading can only load part of it. How to crawl all images Reply content: Crawling image information, but lazy loading can only load part of it, how to crawl all images Lazy loading means that when you slide down, the website will request an interface via Ajax again, which is a bit similar to paging. You need to look at the link of his ajax request and then crawl to the corresponding link. This crawling has something to do with how your regular matching is written. curl just simulates a request

I have some questions about some APIs in php, please give me some advice.
1: There are some APIs in PHP that I don’t know how to use, and I don’t know what scenarios are most suitable for them. Whether it’s parameters or return values, I don’t understand them all. Don’t ask me to read the manual. I’ve read the manual many times. . For example, what can pack be used for? It’s a big headache. There are really many APIs like this that I don’t quite understand the applicable scenarios. Please give me some guidance. 2: php://stdin, php://stdout, php://input are difficult to understand. I really don’t know what they refer to. Please explain them in a simpler way. 3: Asking a question, it is relatively superficial. Many reversible encryption algorithms are written to convert the string into binary and perform bit operations with the secret key. Finally, the encrypted string is obtained, and then the encrypted string is converted into 2. Operate the base and the secret key to get the real string. I just want to know, why do you have to convert it to binary? Why does it have to be converted to binary? why? I don’t understand. Binary bit operations look too awkward! ! ! ! 4: Many frameworks have…
Dear technical experts, I want to learn PHP, please give me some advice.
Programming is a technical job that not everyone can learn. To be able to endure loneliness, those who engage in programming need a heart willing to delve into it. Many companies like people who are self-taught and don’t like people who come from training institutions. Because programming technology is updated day by day, self-learning ability is very important for continuous learning. If you are a person who is good at self-study and make good use of network resources, you can still learn very well and become a programming master. The general tuition fee for learning PHP in training institutions is around 13,000. In fact, after you work, you may not be able to save 13,000 in a year. Therefore, if you want to learn programming, it is best to choose self-study. If after self-study for a period of time, you find that you really can’t do it, then what you should consider is not to go to training, but to consider whether I am capable of programming. Programming is not a big deal. , you can learn if you want to. Programming is not a cabbage, you can learn it if you want, so I want to go for training.…

PHP cutting problem, please give me some advice, I have been working on it for a day.
I use JCROP to obtain the x, y coordinates, width, and height on the front end, and pass them to uphoto.php for processing. Now everything is normal, but if the width of the picture selected by the front-end user is too large (I use css style to control the maximum width of the picture selected by the user to 680px ), the cropped image is abnormal… I checked some information and it said that it needs to be converted in proportion, but at what proportion? Is the width of the image selected by the user (when greater than 680px) converted to 680? This is uphoto.php: $x1 = $_POST[“x1”];$x2 = $ _POST[“x2”];$y1 = $_POST[“y1”];$y2 = $_POST[“y2”];$targ_w = $_POST[“w”];$targ_h = $_POST[“h”] ;if ($_FILES[“mfile”][“error”]){echo “error: ” . $_FILES[“file”][“error”];}if (!empty($_FILES[“mfile”][ “name”])){ //Extract the file domain content name and determine $path = “/upload/user/photo/”; //Upload path//Check whether the folder exists, if not, create it and give it Highest authority //if(!file_exists($path)){mkdir(“$path”, 0700);}//File formats allowed to be uploaded $allow_type = array(“image/gif”,”image/pjpeg”,” image/jpeg”,”image/png”);//Check whether the uploaded file is of a type that is allowed to be uploaded if(!in_array($_FILES[“mfile”][“type”], $allow_type)){echo “error: The format is wrong, only gif/jpg/png is supported”; exit();}//Detect image size if($_FILES[“mfile”][“size”] > 5*1024*1024){echo “error: file Must not exceed…
[PHP] Code function name problem, please give me some advice
