This might help you I mean: , Try this:
$arr1 = array("1", "2");
$arr2 = array("22", "432");

/*
 * Specify the second walkway array as the
 * reference param of the callback function
 * if you want to manipulate it. Otherwise,
 * just pass $arr2.
 */
array_walk($arr1, function ($item1, $key, &$arr2) {

    // Point 1
    echo "$item1<br>";

    array_walk($arr2, function ($item2, $key1) {

        // Point 2
        echo "$item2<br>";

    });
}, $arr2); // Pass the other array to walk in within the walkway
1
22
432
2
22
432

PHP array_walk does nothing?

fixed the issue. Will look into that further array_walk is useful when your callback function accepts a reference or when you use user-defined callback functions. In this case, the basename argument is not a reference.
What you want is array_map:
$files = glob($xsl_dir_path . "/*.xsl");
$files = array_map('basename', $files);

Why does one array_walk work and the other array_walk does not?

will help you I finally figured it out. The reason the array_walk was not working when included in a separate functions file was because the format of my functions.php file was 1252(ANSI-Latin I). I converted it to UTF-8 and now it works. The special MS characters were not being encoded properly when the format was 1252(ANSI-Latin I) which resulted in array_walk not working as desired.

What does array_walk() do?

it fixes the issue The intention of it is that it should convert every item of $arr to integer.
But it does not do that!
<?php
array_walk($arr, 'intval'); // does nothing in PHP 5.3.3
?>
<?php
$arr = array_map('intval', $arr);
?>
<?php
array_walk($arr, function(&$e) { // note the reference (&)
   $e = intval($e);
});
?>

This might help you Having problem on getting the highlights_description. I want to echo the highlights_title and highlights_decription. This is the array , You can scan both arrays together by such foreach
if(!empty($highlights)) {
     foreach(array_map(null, $highlights['highlights_title'], $highlights['highlights_description']) 
              as list($title, $desc)) {
          echo $title.'\t'.$desc."<\br>\n";
     }
}
