I have the following array:
array['Elnett', 'INOA INOA', 'Playball P', 'Preferred Color Specialist',
'Série Expert', 'Série Nature', 'Techni art']
I would like to have keys and values like:
array['Elnett' => 'Elnett',
'INOA INOA' => 'INOA INOA',
'Playball P' => 'Playball',
'Preferred Color Specialis' => 'Preferred Color Specialist',
'Série Expert' => 'Série Expert',
'Série Nature' => 'Série Nature',
'Techni art' => 'Techni art']
How can I accomplish this?

Simple function to replace array keys. Note you have to manually select wether existing keys will be overrided.
/**
* @param array $array
* @param array $replacements
* @param boolean $override
* @return array
*/
function array_replace_keys[array $array, array $replacements, $override = false] {
foreach [$replacements as $old => $new] {
if[is_int[$new] || is_string[$new]]{
if[array_key_exists[$old, $array]]{
if[array_key_exists[$new, $array] && $override === false]{
continue;
}
$array[$new] = $array[$old];
unset[$array[$old]];
}
}
}
return $array;
}

Here is a simple array_replace_keys function:
/**
* This function replaces the keys of an associate array by those supplied in the keys array
*
* @param $array target associative array in which the keys are intended to be replaced
* @param $keys associate array where search key => replace by key, for replacing respective keys
* @return array with replaced keys
*/
private function array_replace_keys[$array, $keys]
{
foreach [$keys as $search => $replace] {
if [ isset[$array[$search]]] {
$array[$replace] = $array[$search];
unset[$array[$search]];
}
}
return $array;
}
// Test Drive
print_r[array_replace_keys[['one'=>'apple', 'two'=>'orange'], ['one'=>'ett', 'two'=>'tvo']];
// Output
array[
'ett'=>'apple',
'tvo'=>'orange'
]

To get exactly same result like in PHP 5.3, the foreach loop in your code should look like:
Check on this code:
Function array_replace "replaces elements from passed arrays into the first array" -- this means replace from top-right to first, then from top-right - 1 to first, etc, etc...

In some cases you might have a structured array from the database and one
of its nodes goes like this;
Now consider that you want to capture $arr values from $keys.
Assuming that you have a limitation to display the content into given keys
order, i.e. use it with a vsprintf, you could use the following
I hope that this will save someone's time.

I got hit with a noob mistake. :]
When the function was called more than once, it threw a function redeclare error of course. The enviroment I was coding in never called it more than once but I caught it in testing and here is the fully working revision. A simple logical step was all that was needed.
With PHP 5.3 still unstable for Debian Lenny at this time and not knowing if array_replace would work with multi-dimensional arrays, I wrote my own. Since this site has helped me so much, I felt the need to return the favor. :]
