[PHP] Replace values in array recursively

replace_array.php

<?php
/**
* The following code will replace array that has values equalt to keys in another one.
* Example:
* $config = [
*    'key1' => 'value1',
*    'key2' => 'value2',
*    'subkeys' => [
*        'subkey1' => 'subvalue1',
*        'subkey2' => 'subvalue2'
*     ]
*  ];
*  
*  $parameters = [
*    'value1' => 123,
*    'value2' => 345
*  ];
*  
*  Running the following code will make config array like this:
*  
*  $config = [
*    'key1' => 123,
*    'key2' => 345,
*    'subkeys' => [
*        'subkey1' => 'subvalue1',
*        'subkey2' => 'subvalue2'
*     ]
*  ];
