Modeling Hierarchical Data Structures with PHP Multidimensional Arrays
Article Introduction：Use multi-dimensional arrays and recursive functions to effectively process hierarchical data in PHP. First, build flat data into a tree structure. 1. Recursively organize parent-child relationships through the buildTree function; 2. Recursively generate nested HTML lists using the renderTree function; 3. Use helper functions such as findNodeById to search nodes; 4. Pay attention to the recursive performance overhead, cache the tree structure or use iterative methods when necessary, so as to efficiently implement traversal, rendering and query. This method is suitable for classification, menu and other scenarios, and is a flexible and practical solution.
