Article Introduction：Operating CSV files in PHP is mainly implemented through fgetcsv and fputcsv functions. 1) Read CSV file. Use the fgetcsv function to read and process data line by line. 2) Write to CSV file. Use the fputcsv function to write array data to the file. Note that line-by-line reading is used when file encoding and large file processing to optimize performance.

Article Introduction：Reading CSV files can be implemented in Python through the csv module and pandas library. Use the csv module without dependencies, and is suitable for simple scenarios. The example code is: importcsvwithopen('data.csv',mode='r',encoding='utf-8')asfile:reader=csv.DictReader(file)forrowinreader:print(row), which can read data and output it in dictionary; if you need a list form, csv.reader() can be used. Pandas is more efficient and is especially suitable for data analysis. The sample code is: importpan

Article Introduction：The core method of reading CSV files in Go language is to use the standard library encoding/csv. The specific steps are as follows: 1. Open the file and create a CSVreader with os.Open; 2. Read the data using reader.ReadAll() or line-by-line Read() method; 3. Handle possible format problems, such as quotes, comma nesting, blank lines, etc.; 4. CSV data can be mapped to the structure through a third-party library (such as gocsv) to improve operability. The whole process is simple and direct, but attention should be paid to details such as field order, format consistency and error handling.

Article Introduction：The steps to write CSV files in Go are as follows: 1. Open or create a file; 2. Initialize csv.Writer; 3. Use Write or WriteAll to write data; 4. Call Flush to ensure that the data is dropped. The standard library encoding/csv automatically processes data containing commas or quotes without manual escape. In addition, you can change the separator by setting Writer.Comma and control the line break format through UseCRLF to meet the needs of different scenarios.

Article Introduction：Go language processes CSV files directly and efficiently, and the standard library encoding/csv can meet most needs. When reading, use csv.NewReader() to create a reader, and read data through ReadAll() or line by line; if the title line is included, you can skip the first line and set TrimLeadingSpace to remove spaces or Comma to replace the separator. When writing, use csv.NewWriter() to create a writer, call Write()/WriteAll() to output data. Note that the os.O_APPEND flag is required to add content and be sure to call Flush() to ensure that the data is landed. When handling special characters, the CSV package supports RFC4180 specification by default, and the comma in the field is

Article Introduction：The Python encryption library is used as follows: 1. Symmetric encryption is recommended to use the Fernet module in the cryptography library. The key is generated by generate_key() and the data is encrypted and decrypted with encrypt()/decrypt(); 2. The hashlib library can be used to calculate hashlib, and the SHA256 algorithm is preferred and the hash value is obtained through hexdigest(). Pay attention to avoiding MD5 and SHA1; 3. Asymmetric encryption can use the RSA function of cryptography to generate key pairs through generate_private_key(), and use public key encryption and private key decryption. Note that filling schemes such as OAEP must be used and only suitable

Article Introduction：Many websites and applications are developed to require various types of data to simulate how real life works. During the testing and development stages of a project, we often use fake data to fill databases, UI elements, and so on. Writing your own code to generate fake data for your project can be very cumbersome. In this tutorial, you will learn how to generate fake data using the proven Faker library in PHP. getting Started Before I continue, I want to clarify a few points. The original fake library was fzaninotto/Faker. However, it was archived by the owner on December 11, 2020. Now, the library branch called FakerPHP/Faker is continuing its development work.
