array_shift - Shift an element off the beginning of array

SYNOPSIS

       mixed array_shift (array  &$array)

DESCRIPTION

       array_shift(3)  shifts  the  first value of the $array off and returns it, shortening the $array by one element and moving everything down.
       All numerical array keys will be modified to start counting from zero while literal keys won't be touched.

       Note

	      This function will reset(3) the array pointer of the input array after use.

PARAMETERS

	      o $array
		- The input array.

RETURN VALUES

	Returns the shifted value, or NULL if $array is empty or is not an array.

EXAMPLES

       Example #1

	      array_shift(3) example

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

	      The above example will output:

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

	       and orange will be assigned to $fruit.

ARRAY_REPLACE(3)							 1							  ARRAY_REPLACE(3)

array_replace - Replaces elements from passed arrays into the first array

SYNOPSIS

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

DESCRIPTION

       array_replace(3)  replaces  the values of $array1 with values having the same keys in each of 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 arrays overwriting the previous values.

       array_replace(3) is not recursive : it will replace values in the first array by whatever type is in the second array.

PARAMETERS

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

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

	      o $...
		- More arrays from which elements will be extracted. Values from later arrays overwrite the previous values.

RETURN VALUES

	Returns an array, or NULL if an error occurs.

EXAMPLES

       Example #1

	      array_replace(3) example

	      <?php
	      $base = array("orange", "banana", "apple", "raspberry");
	      $replacements = array(0 => "pineapple", 4 => "cherry");
	      $replacements2 = array(0 => "grape");

	      $basket = array_replace($base, $replacements, $replacements2);
	      print_r($basket);
	      ?>

	      The above example will output:

	      Array
	      (
		  [0] => grape
		  [1] => banana
		  [2] => apple
		  [3] => raspberry
		  [4] => cherry
	      )
