In this issue, the editor will bring you about the ways of array merging in php. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

1. For the same string index

Array_merge will overwrite the previous values with the latter values.

+ will overwrite the same key after the same value with the previous value

Array_merge_recursive will put the same index in an array, increasing the dimension of the array.

two。 For the same digital index

Array_merge will re-index duplicate values (index values will change and re-index from 0)

+ still overwrite the following values with the values that have appeared before

Array_merge_recursive is handled in the same way as array_merge.

These are the ways of merging arrays in the php shared by the editor. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
