I reviewed Don Cragun's comments and he was correct asking "annacreek" politely if he or she had reviewed the docs.
I did not see any "superior attitude" or anything negative in Don's reply, and this is a warning to annacreek.

array_flip
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
)
Example #2
array_flip(3) example : collision
<?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
)
