need help iterating through array generated by yaml (php)

Question

I'm creating a symfony2 application that searches and replaces strings from files

I created a yaml file with the following content:

parameters:
         file.search_and_replace:
                 "path/dir/filename":
                        replace: 'word'
                        with: 'anotherword'

                 "path_2/dir/filename_2":
                        replace: 'apples'
                        with: 'oranges'

now to fetch the content I use the following syntax:

$array = $this->getContainer()->getParameter('file.search_and_replace');

If I dump the variable like this:

var_dump($array);

it returns

array(2) 
{
  'path/file/filename' =>
    array(2) 
    {
      'replace' => string(4) "word"
      'with' => string(11) "anotherword"
    }
  'path_2/file/filename_2' =>
    array(2) 
    {
     'replace' => string(6) "apples"
     'with' =>    string(7) "oranges"
    }
}

I need to find a way to loop through this array so I can pass the content to a function I created, that needs the following parameters:

searchAndReplace('filepath','replace_this_word','with_this_word');

something like:

foreach($array as $file)
{
    searchAndReplace($file.path,$file.replace,$file.with);  
}

You're close.

Two things:

foreach can accept a key => value syntax. Using this you can get the path.
PHP does not use dot notation for arrays. It uses brackets.

Try the following:

foreach ($array as $path => $sub) {
    searchAndReplace($path,$sub['replace'],$sub['with']);  
}
