js implements passing complex json parameters to controller

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.

C++ parameter type safety checking ensures that functions only accept values ​​of expected types through compile-time checks, run-time checks, and static assertions, preventing unexpected behavior and program crashes: Compile-time type checking: The compiler checks type compatibility. Runtime type checking: Use dynamic_cast to check type compatibility, and throw an exception if there is no match. Static assertion: Assert type conditions at compile time.

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

An open source model that can beat GPT-4 has appeared! The latest battle report of the large model arena: the 104 billion parameter open source model CommandR+ climbed to 6th place, tying with GPT-4-0314 and surpassing GPT-4-0613. Image This is also the first open-weight model to beat GPT-4 in the large model arena. The large model arena is one of the only test benchmarks that the master Karpathy trusts. Image CommandR+ from AI unicorn Cohere. The co-founder and CEO of this large model startup is none other than Aidan Gomez, the youngest author of Transformer (referred to as the wheat harvester). As soon as this battle report came out, another wave of big model clubs started

Reference parameters in C++ functions (essentially variable aliases, modifying the reference modifies the original variable) and pointer parameters (storing the memory address of the original variable, modifying the variable by dereferencing the pointer) have different usages when passing and modifying variables. Reference parameters are often used to modify original variables (especially large structures) to avoid copy overhead when passed to constructors or assignment operators. Pointer parameters are used to flexibly point to memory locations, implement dynamic data structures, or pass null pointers to represent optional parameters.

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.

JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.
