ARRAY_PUSH(3)								 1							     ARRAY_PUSH(3)

array_push - Push one or more elements onto the end of array

SYNOPSIS

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

DESCRIPTION

       array_push(3)  treats $array as a stack, and pushes the passed variables onto the end of $array. The length of $array increases by the num-
       ber of variables pushed. Has the same effect as:

       <?php
       $array[] = $var;
       ?>

       Note

	       If you use array_push(3) to add one element to the array it's better to use $array[] =  because in that way there is no overhead of
	      calling a function.

       Note

	      array_push(3)  will  raise a warning if the first argument is not an array. This differs from the $var[] behaviour where a new array
	      is created.

PARAMETERS

	      o $array
		- The input array.

	      o $value1
		- The first value to push onto the end of the $array.

RETURN VALUES

	Returns the new number of elements in the array.

EXAMPLES

       Example #1

	      array_push(3) example

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

	      The above example will output:

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

array_splice - Remove a portion of the array and replace it with something else

SYNOPSIS

       array array_splice (array  &$input, int	$offset, [int  $length], [mixed  $replacement = array()])

DESCRIPTION

	Removes  the  elements	designated  by	$offset and $length from the $input array, and replaces them with the elements of the $replacement
       array, if supplied.

	Note that numeric keys in $input are not preserved.

       Note

	       If $replacement is not an array, it will be typecast to one (i.e. (array) $parameter). This may result in unexpected behavior  when
	      using an object or NULL$replacement.

PARAMETERS

	      o $input
		- The input array.

	      o $offset
		- If $offset is positive then the start of removed portion is at that offset from the beginning of the $input array. If $offset is
		negative then it starts that far from the end of the $input array.

	      o $length
		- If $length is omitted, removes everything from $offset to the end of the array. If $length is specified and  is  positive,  then
		that  many elements will be removed. If $length is specified and is negative then the end of the removed portion will be that many
		elements from the end of the array. If $length is specified and is zero, no elements will be removed. Tip:  to	remove	everything
		from $offset to the end of the array when $replacement is also specified, use count($input) for $length.

	      o $replacement
		-  If  $replacement  array  is	specified,  then  the removed elements are replaced with elements from this array.  If $offset and
		$length are such that nothing is removed, then the elements from the $replacement array are inserted in the place specified by the
		$offset.  Note	that  keys in replacement array are not preserved.  If $replacement is just one element it is not necessary to put
		array() around it, unless the element is an array itself, an object or NULL.

RETURN VALUES

	Returns the array consisting of the extracted elements.

EXAMPLES

       Example #1

	      array_splice(3) examples

	      <?php
	      $input = array("red", "green", "blue", "yellow");
	      array_splice($input, 2);
	      // $input is now array("red", "green")

	      $input = array("red", "green", "blue", "yellow");
	      array_splice($input, 1, -1);
	      // $input is now array("red", "yellow")

	      $input = array("red", "green", "blue", "yellow");
	      array_splice($input, 1, count($input), "orange");
	      // $input is now array("red", "orange")

	      $input = array("red", "green", "blue", "yellow");
	      array_splice($input, -1, 1, array("black", "maroon"));
	      // $input is now array("red", "green",
	      //	  "blue", "black", "maroon")

	      $input = array("red", "green", "blue", "yellow");
	      array_splice($input, 3, 0, "purple");
	      // $input is now array("red", "green",
	      //	  "blue", "purple", "yellow");
	      ?>

       Example #2

	      array_splice(3) examples

	       The following statements change the values of $input the same way:

	      <?php
	      array_push($input, $x, $y);
	      array_splice($input, count($input), 0, array($x, $y));
	      array_pop($input);
	      array_splice($input, -1);
	      array_shift($input);
	      array_splice($input, 0, 1);
	      array_unshift($input, $x, $y);
	      array_splice($input, 0, 0, array($x, $y));
	      $input[$x] = $y; // for arrays where key equals offset
	      array_splice($input, $x, 1, $y);
	      ?>
