array_unshift(3) [php man page]

ARRAY_UNSHIFT(3)							 1							  ARRAY_UNSHIFT(3)

array_unshift - Prepend one or more elements to the beginning of an array

SYNOPSIS

       int array_unshift (array  &$array, mixed  $value1, [mixed  $...])

DESCRIPTION

       array_unshift(3)  prepends  passed elements to the front of the $array. Note that the list of elements is prepended as a whole, so that the
       prepended elements stay in the same order. All numerical array keys will be modified to start counting from zero while literal  keys  won't
       be touched.

PARAMETERS

	      o $array
		- The input array.

	      o $value1
		- First value to prepend.

RETURN VALUES

	Returns the new number of elements in the $array.

EXAMPLES

       Example #1

	      array_unshift(3) example

	      <?php
	      $queue = array("orange", "banana");
	      array_unshift($queue, "apple", "raspberry");
	      print_r($queue);
	      ?>

	      The above example will output:

	      Array
	      (
		  [0] => apple
		  [1] => raspberry
		  [2] => orange
		  [3] => banana
	      )

array_replace_recursive - Replaces elements from passed arrays into the first array recursively

SYNOPSIS

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

DESCRIPTION

       array_replace_recursive(3) replaces the values of $array1 with the same values from all the following arrays. If a key from the first array
       exists in the second array, its value will be replaced by the value from the second array. If the key exists in the second array,  and  not
       the  first,  it	will  be created in the first array. If a key only exists in the first array, it will be left as is. If several arrays are
       passed for replacement, they will be processed in order, the later array overwriting the previous values.

       array_replace_recursive(3) is recursive : it will recurse into arrays and apply the same process to the inner value.

	When the value in $array1 is scalar, it will be replaced by the value in $array2, may it be scalar or array. When the value in $array1 and
       $array2 are both arrays, array_replace_recursive(3) will replace their respective value recursively.

PARAMETERS

	      o $array1
		- The array in which elements are replaced.

	      o $array2
		- The array from which elements will be extracted.

	      o $...
		- Optional. More arrays from which elements will be extracted.

RETURN VALUES

	Returns an array, or NULL if an error occurs.

EXAMPLES

       Example #1

	      array_replace_recursive(3) example

	      <?php
	      $base = array('citrus' => array( "orange") , 'berries' => array("blackberry", "raspberry"), );
	      $replacements = array('citrus' => array('pineapple'), 'berries' => array('blueberry'));

	      $basket = array_replace_recursive($base, $replacements);
	      print_r($basket);

	      $basket = array_replace($base, $replacements);
	      print_r($basket);
	      ?>

	      The above example will output:

	      Array
	      (
		  [citrus] => Array
		      (
			  [0] => pineapple
		      )

		  [berries] => Array
		      (
			  [0] => blueberry
			  [1] => raspberry
		      )

	      )
	      Array
	      (
		  [citrus] => Array
		      (
			  [0] => pineapple
		      )

		  [berries] => Array
		      (
			  [0] => blueberry
		      )

	      )

       Example #2

	      array_replace_recursive(3) and recursive behavior

	      <?php
	      $base = array('citrus' => array("orange") , 'berries' => array("blackberry", "raspberry"), 'others' => 'banana' );
	      $replacements = array('citrus' => 'pineapple', 'berries' => array('blueberry'), 'others' => array('litchis'));
	      $replacements2 = array('citrus' => array('pineapple'), 'berries' => array('blueberry'), 'others' => 'litchis');

	      $basket = array_replace_recursive($base, $replacements, $replacements2);
	      print_r($basket);

	      ?>

	      The above example will output:

	      Array
	      (
		  [citrus] => Array
		      (
			  [0] => pineapple
		      )

		  [berries] => Array
		      (
			  [0] => blueberry
			  [1] => raspberry
		      )

		  [others] => litchis
	      )
