I have a very basic doubt about PHP, please give me some advice.
A very basic problem with PHP, please give me some advice<?php $upfile=$_FILES[“upfile”];?> Upload File The above is the code Content, when I run the web page, I always get an error message from the $upfile=$_FILES[“upfile”]; line. What went wrong? ——Solution——————– Well… Actually, this is a prompt. It is an improvement of PHP after version 5.x. If you feel irritated, you can block these prompts by turning off the error prompts in php.ini. , of course I don’t recommend doing this. Therefore, such submitted value issues can be judged through isset. If it is a variable, it can be solved by initialization assignment.

Regarding the LazyPHP framework, please give me some advice.
Regarding the LazyPHP framework, need guidance? $data[‘title’] = $data[‘top_title’] = ‘Homepage’; Finally, what does the equal sign “Home Page” mean? Is the render function equivalent to $ob->assign? Share to: assign? data-pics=”> ——Solution——————–$data[ ‘title’] = $data[‘top_title’] = ‘Homepage’; Assign values to $data[‘title’] and $data[‘top_title’] at the same time The render function is used to load and execute templates The template is still php-html mixed code LazyPHP is only responsible for scheduling between modules The sample files need to be run in an environment with short tags enabled Since there is no template engine and ORM, 1.18M seems too bloated——Solution—————- —- Quote: $data[‘title’] = $data[‘top_title’] = ‘Home’ ; Finally, what does the equal sign “Home Page” mean? Is the render function equivalent to $ob->assign Lao Han, can you do it?——Solution——————– Doesn’t the equal sign mean assignment?

Help!!! Set up a small site for a class meeting, I sincerely ask for help, please give me some advice, I will learn it myself_html/css_WEB-ITnose-html tutorial
html webpage for help The class will play a psychology game: write down 5 things that you think are important, and then delete the things that you think you can do without or discard one by one… Then make a website, probably two web pages. One is for students to open the page on their mobile phones and enter their student ID and 5 important things in life in the two boxes. Then create another web page. Divide the entire web page into 28 vertical grids and display the 5 submitted items in each grid for projection. Further functions are: students can delete on the mobile page, and on another page (with 28 grids) they can press refresh to see what is left in each grid. and things that were deleted (red line in the middle). I really don’t understand, please give me some advice! This thing is a kind of collective communication and sharing, which improves the boring and monotonous writing of psychology games on paper. Finally, I would like to sincerely ask for help. Please give me some advice on what knowledge is needed, how to implement it in the simplest way, etc. . . Thanks again! Reply…
PHP constant problem: Comparison between const and define, please give me some advice
Only for the speed issue, let’s not mention usage for now. I saw someone on the Internet saying that Const is a structural syntax and its speed will be several times higher than the define function. I need a professional explanation. Is this true? Now that const can indeed be used outside a class, will everyone give it priority when defining constants? Reply content: Only for the speed issue, let’s not mention the usage for now. I saw someone on the Internet saying that Const is a structural grammar and its speed will be several times higher than the define function. I need a professional explanation. Is this true? Now that const can indeed be used outside a class, will everyone give it priority when defining constants? For speed comparison, I suggest you write a few lines of code to test it yourself, which is much better than asking here. Speed: If const is faster, it is also a subtle difference, and it does not make much sense to consider this If const was better, the documentation would recommend you to use it, but it’s not, so don’t worry about it Will you give priority to using const: Based on…
