JavaScript object-oriented - creation of simple objects and JSON objects

Performance optimization methods for converting PHP arrays to JSON include: using JSON extensions and the json_encode() function; adding the JSON_UNESCAPED_UNICODE option to avoid character escaping; using buffers to improve loop encoding performance; caching JSON encoding results; and considering using a third-party JSON encoding library.

Annotations in the Jackson library control JSON serialization and deserialization: Serialization: @JsonIgnore: Ignore the property @JsonProperty: Specify the name @JsonGetter: Use the get method @JsonSetter: Use the set method Deserialization: @JsonIgnoreProperties: Ignore the property @ JsonProperty: Specify name @JsonCreator: Use constructor @JsonDeserialize: Custom logic

Go language supports object-oriented programming through type definition and method association. It does not support traditional inheritance, but is implemented through composition. Interfaces provide consistency between types and allow abstract methods to be defined. Practical cases show how to use OOP to manage customer information, including creating, obtaining, updating and deleting customer operations.

OOP best practices in PHP include naming conventions, interfaces and abstract classes, inheritance and polymorphism, and dependency injection. Practical cases include: using warehouse mode to manage data and using strategy mode to implement sorting.

There is no concept of a class in the traditional sense in Golang (Go language), but it provides a data type called a structure, through which object-oriented features similar to classes can be achieved. In this article, we'll explain how to use structures to implement object-oriented features and provide concrete code examples. Definition and use of structures First, let's take a look at the definition and use of structures. In Golang, structures can be defined through the type keyword and then used where needed. Structures can contain attributes

The Go language supports object-oriented programming, defining objects through structs, defining methods using pointer receivers, and implementing polymorphism through interfaces. The object-oriented features provide code reuse, maintainability and encapsulation in the Go language, but there are also limitations such as the lack of traditional concepts of classes and inheritance and method signature casts.

PHP arrays can be converted to JSON strings through the json_encode() function (for example: $json=json_encode($array);), and conversely, the json_decode() function can be used to convert from JSON to arrays ($array=json_decode($json);) . Other tips include avoiding deep conversions, specifying custom options, and using third-party libraries.

PHP provides the following functions to process JSON data: Parse JSON data: Use json_decode() to convert a JSON string into a PHP array. Create JSON data: Use json_encode() to convert a PHP array or object into a JSON string. Get specific values ​​of JSON data: Use PHP array functions to access specific values, such as key-value pairs or array elements.
