array_merge_recursive - Merge two or more arrays recursively

SYNOPSIS
       array array_merge_recursive (array  $array1, [array  $...])

DESCRIPTION
       array_merge_recursive(3) merges the elements of one or more arrays together so that the values of one are appended to the end of the previ-
       ous one. It returns the resulting array.

	If the input arrays have the same string keys, then the values for these keys are merged together into an array, and this is  done  recur-
       sively,	so  that  if one of the values is an array itself, the function will merge it with a corresponding entry in another array too. If,
       however, the arrays have the same numeric key, the later value will not overwrite the original value, but will be appended.

PARAMETERS
	      o $array1
		- Initial array to merge.

	      o $...
		- Variable list of arrays to recursively merge.

RETURN VALUES
	An array of values resulted from merging the arguments together.

EXAMPLES
       Example #1

	      array_merge_recursive(3) example

	      <?php
	      $ar1 = array("color" => array("favorite" => "red"), 5);
	      $ar2 = array(10, "color" => array("favorite" => "green", "blue"));
	      $result = array_merge_recursive($ar1, $ar2);
	      print_r($result);
	      ?>

	      The above example will output:

	      Array
	      (
		  [color] => Array
		      (
			  [favorite] => Array
			      (
				  [0] => red
				  [1] => green
			      )

			  [0] => blue
		      )

		  [0] => 5
		  [1] => 10
	      )
