PHP array_merge_recursive Function

Defintion :

The array_merge_recursive() function merge one or more arrays into one array recursively.

This function merges the elements of one or more arrays together in such a way that the values of one are appended to the end of the previous one. It returns a new array with merged elements.

Note: If you assign only one array to the array_merge_recursive() function, it will behave exactly the same as the array_merge() function.

Syntax:

array_merge_recursive(array1, array2, array3, ...)

Parameter Values:

Parameter	Description
array1	Required. Specifies an array
array2	Optional. Specifies an array
array3,...	Optional. Specifies an array
