Article Introduction：Comparison of PHP array merging efficiency: The time complexity of the three methods Array_merge(), + operator and Array_replace() is all O(n), which means that the merging time is proportional to the number of array elements. The space complexity of these three methods is also O(n), which means that the memory usage is proportional to the number of array elements.
