The php array_replace function replaces the elements of the first array with the passed array

array_replace() function replaces the value of the first array with the value of the following array. You can pass an array or multiple arrays to the function. This article explains how to use the php array_replace function through examples. Coders who need it can refer to it.

array_replace function syntax:

array array_replace ( array $array1 , array $array2 [, array $... ] )

array_replace() function replaces the value of the array1 array with the value of the same key of the subsequent array element. If a key exists in the first array and also exists in the second array, its value will be replaced by the value in the second array.
