My var_dump stop working, how can i fix it?

Question

When I use the function var_dump, in my file php, It doesn't print the array like before. I haven't touched the file php.ini in my wampserver,

function getFolder_recursive(&$array,$dir){

if(is_dir($dir)){
    $handle=opendir($dir);
    while (false!== ($entry=readdir($handle))) {
        if ($entry != "." && $entry != "..") {
            if (is_dir($dir.$entry)){
                $allFiles[]= "D: " . $dir . "/" . $entry;

               // echo "<a href='http://localhost/eclipse/access_log/logfiles.php?cartella=$c' class='btn btn-light>Cartella</a>";
            }
            else{
                $allFiles[]="F: " . $dir . "/" . $entry;
            }
        }
    }
    closedir($handle);
--> var_dump($allFiles);
}
return $array;     

}

This is how it prints:

array(7) { [0]=> string(22) "D: files/log_files//10" [1]=> string(21) "D: files/log_files//2" [2]=> string(21) "D: files/log_files//3" [3]=> string(21) "D: files/log_files//4" [4]=> string(21) "D: files/log_files//6" [5]=> string(21) "D: files/log_files//7" [6]=> string(21) "D: files/log_files//

I expect that var_dump prints my array formatted

Just add <pre> tags

function getFolder_recursive(&$array,$dir){

    if(is_dir($dir)){
        $handle=opendir($dir);
        while (false!== ($entry=readdir($handle))) {
            if ($entry != "." && $entry != "..") {
                if (is_dir($dir.$entry)){
                    $allFiles[]= "D: " . $dir . "/" . $entry;

                   // echo "<a href='http://localhost/eclipse/access_log/logfiles.php?cartella=$c' class='btn btn-light>Cartella</a>";
                }
                else{
                    $allFiles[]="F: " . $dir . "/" . $entry;
                }
            }
        }
        closedir($handle);
        echo "<pre>";
        var_dump($allFiles);
        echo "</pre>"
    }
    return $array;     
}
