ARRAY_FLIP(3)								 1							     ARRAY_FLIP(3)

array_flip - Exchanges all keys with their associated values in an array

SYNOPSIS

       array array_flip (array	$array)

DESCRIPTION

       array_flip(3) returns an array in flip order, i.e. keys from $array become values and values from $array become keys.

	Note  that the values of $array need to be valid keys, i.e. they need to be either integer or string. A warning will be emitted if a value
       has the wrong type, and the key/value pair in question will not be included in the result.

	If a value has several occurrences, the latest key will be used as its value, and all others will be lost.

PARAMETERS

	      o $array
		- An array of key/value pairs to be flipped.

RETURN VALUES

	Returns the flipped array on success and NULL on failure.

EXAMPLES

       Example #1

	      array_flip(3) example

	      <?php
	      $input = array("oranges", "apples", "pears");
	      $flipped = array_flip($input);

	      print_r($flipped);
	      ?>

	      The above example will output:

	      Array
	      (
		  [oranges] => 0
		  [apples] => 1
		  [pears] => 2
	      )

	      <?php
	      $input = array("a" => 1, "b" => 1, "c" => 2);
	      $flipped = array_flip($input);

	      print_r($flipped);
	      ?>

	      The above example will output:

	      Array
	      (
		  [1] => b
		  [2] => c
	      )
