function array_iconv($in_charset,$out_charset,$arr){ return eval('return '.iconv($in_charset,$out_charset,var_export($arr,true).';')); }Copy code principle analysis : var_export sets the second parameter to true, returns the array prototype string, converts the string to utf-8 encoding, and then uses eval to perform the return (similar to an anonymous function?), which perfectly solves the problem. Subsequent: The method found online is mostly the method of calling iconv recursively. If the array elements are too large or the number of dimensions is more, the performance is definitely not good. The array is still associated with an array, and everything has been automatically completed, ensuring that the data before and after the array conversion is consistent. In terms of the length of the code and the comparison of the cycle and native methods, the method of this article is good.

## :: PHP number array encoding conversion Due to the display effect of some special characters, the UTF-8 project of the habit has been changed to GBK. Because AJAX technology is used, it also involves old problems -coding conversion. Some form verification needs to return JSON data. The json_encode function of the php only supports UTF-8 coding. Helpless ICONV is helpless. The effect that needs to be achieved is that the GBK array is converted to the UTF-8 array and passed to the json_encode function. The initial idea is to

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
