  • Recursive Search Strategies for Deeply Nested PHP Arrays
    Recursive Search Strategies for Deeply Nested PHP Arrays
    To effectively search for deep nested PHP arrays, you need to use recursive methods. 1. Check whether the value exists: by traversing each element and recursively checking the child array, return true immediately once the target value is found; 2. Check whether the key exists: traverse the key name layer by layer, and return true if the current key matches or the key is found in the child array; 3. Find the complete path of the key: record the path during the recursive process, and return the complete sequence of key names from the root to the key when the key is found; 4. Return the parent array containing the target key: after positioning the key, return its direct parent array for context operations; 5. Performance optimization suggestions: Avoid deep copy, use strict comparison, and terminate the search as soon as possible. For frequent queries, the array can be flattened into a point-delimited key name structure to achieve fast search, recursion is suitable for complex

    Optimize MySQL performance: mysqli extensions and exec calls
    This article aims to compare the performance differences in using mysqli extension in PHP and calling MySQL client programs through exec functions to execute SQL queries.
