Convert SplFileInfo to String

I'm using a DirectoryIterator to get a folder's contents, and it works just fine :

$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator(__DIR__ . $this->certificate), RecursiveIteratorIterator::SELF_FIRST);

foreach ($iterator as $key => $value) {
    array_push($files, $value);
}
unset($value);

But my $files result when printed it isn't a string but a STD Class. How could I convert that output as a string ( in case there's only one file ) or to an array ?

EDIT : This would be the result I get :

{ [0]=> object(SplFileInfo)#5 (2) { ["pathName":"SplFileInfo":private]=> string(101) "C:\Users\rgr\Apache\htdocs\Roland Groza [ 3.0 ]\class\mongohq/certificate\GTECyberTrustGlobalRoot.crt" ["fileName":"SplFileInfo":private]=> string(27) "GTECyberTrustGlobalRoot.crt" } }

You can use iterator_to_array() coupled with array_keys(). 

print_r(array_keys(iterator_to_array($iterator)));

By default, the flags of RecursiveDirectoryIterator are:

FilesystemIterator::KEY_AS_PATHNAME
FilesystemIterator::CURRENT_AS_FILEINFO

Which uses the current file name as the iterator key and an instance of SplFileInfo as the iterator value.

$value is instance of SplFileInfo, if u need filename push $key or $value->__toString() to $files

You can simply use 

array_push((array)$files, $value);

But if $files have multi std class, use Yogesh suggest.

The easiest way would be type casting (more specific array casting):

$foo = new stdClass();
$foo->bar = 'baz';
$foo->boo = 'far';
$arr = (array)$foo;
var_dump($arr);
/*
array(2) {
  ["bar"]=>
  string(3) "baz"
  ["boo"]=>
  string(3) "far"
}
*/

Well, $files seems to be an array in your example. You are pushing values onto it.

As for converting a stdClass to array you can convert it by casting:

$obj = new stdClass;
$arr = (array) $obj;

You can also do it the other way around:

$arr = array();
$obj = (object) $arr;

If you want a string out of an object or an array then you need to dereference it:

$str = $arr['key'];
$str = $obj->property;

Does this answer your question or am I misunderstanding you?

use this function to convert from std class object to array

 function objectToArray($d) {
    if (is_object($d)) {
        // Gets the properties of the given object
        // with get_object_vars function
        $d = get_object_vars($d);
    }

    if (is_array($d)) {
        /*
        * Return array converted to object
        * Using __FUNCTION__ (Magic constant)
        * for recursive call
        */
        return array_map(__FUNCTION__, $d);
    }
    else {
        // Return array
        return $d;
    }
}

 $arr = objectToArray(files);
 print_r($arr);
