}We know that one of the most important features of the PHP language is arrays (especially associative arrays).
PHP also provides many functions and class interfaces to facilitate array operations, but there is no comprehensive class specifically used to operate arrays.
If there are not many array operations, individual functions will be more flexible to use and have less overhead.
However, if you frequently operate arrays, especially if you perform various operations on arrays such as sorting, pushing onto the stack, dequeuing, flipping, iterating, etc., the system functions may not be so elegant to use.
Today I will introduce to you collectionsPHP’s collection abstract library for operating arrays.
