PHP array_replace() Function
PHP array_replace() Function in PHP language generally replaces the values of the first array with the values from the following arrays.
Please note that the programmer can assign one array to the function or as many as they like to add.
In case, a key from the array1 exists in the array2 then the values from array1 will be generally replaced by the values from the array2. In case, the key only exists in the array1 then it will be left as it is without any change.
Here is another case in which a key exist in the array2 and not in the array1 then this will be created in the array1.
However, if the multiple arrays are being used, then the values from later arrays will generally overwrite the previous ones.
Please note that use of the array_replace_recursive() function in order to replace the values of array1 with the values from the following arrays recursively will be better.
Syntax:
array_replace(array1, array2, array3, ...)
