Today’s tasks:
1. Refer to StarNet Ruijie’s batch import and supplement the batch import design plan in the address book
Functional design: 1. Let users select fields 2. Generate a template in csv format 3. Fill in the csv according to the detailed field description 4. Import
Result: No need for the first step; output the document and communicate with yk
2. Build the PHP development environment and project framework in the virtual machine
studyphp
omui + php + mysql
Result: Complete the login function of the project
Today Work summary:
1. Find the corresponding person in time to communicate: yk==》sn==》wxl, log in to StarNet Ruijie’s device to refer to the batch import operation, and then design a batch import plan for the corporate address book
http:// 192.168.10.186
2. Set up a PHP development environment on the virtual machine. The front-end uses the UCS network management interface and the back-end uses PHP. First of all, we need to ensure that the environment is available, so we built the integrated development environment studyphp at the beginning to improve development efficiency. Gains:
1. Learned and mastered the development method of sublime text3, and quickly used hotkey for efficient development (ctrl+P ctrl+ shift+F two ways to search; ctrl+D to edit multiple identical places; ctrl+/ and ctrl+shift+/ two comments)
2. Regarding error redirection in nginx.conf: there is a switch in the configuration file Configuration----fastcgi_intercept_errors off|on
The above introduces 2015.02.27-referring to other people's implementation methods, communicating in time, quickly setting up the environment, using Sublime Text3, nginx error redirection, including aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
