array_replace_recursive

Name:array_replace_recursive

Category:Array

Programming Language:php

One-line Description:Recursively replace the value of the first array with the value of the following array.

Definition and usage

The array_replace_recursive() function recursively replaces the value of the first array with the value of the following array.

Tip: You can pass an array, or multiple arrays to the function.

If a key exists in the first array array1 and also in the second array2 , the value in the first array array1 will be replaced by the value in the second array array2 . If a key exists only in the first array array1 , it will remain unchanged. If a key exists in the second array array2 but does not exist in the first array array1 , this element is created in the first array array1 . If multiple replacement arrays are passed, they will be processed in sequence, and the values of the subsequent array will overwrite the values of the previous array.

Note: If no key is specified for each array, the function's behavior will be equivalent to array_replace() function.
