I have this problem, I want to use `opendir` with this array of directories, it is possible? with a fixed url I can read files with `readdir`. But I dont know what to do with multiple directories...   

Creating the array:

```
$results = mysqli_query($connecDB,"SELECT * FROM brands WHERE 1 IN (php, ruby, java) ORDER BY id ASC");

//select all records with value "1" in different columns "php ruby java".
// The value "1" indicates a folder created named $id in php, ruby and/or java folder

$resultsArray = array();

while($row = mysqli_fetch_assoc($results)){
    if($row['php'] == 1) {
        $resultsArray['php'][] = $row['id'];
    }
    if($row['java'] == 1) {
        $resultsArray['java'][] = $row['id'];
    }
    if($row['ruby'] == 1) {
        $resultsArray['ruby'][] = $row['id'];
    }
}

foreach($resultsArray as $language => $array){
    echo "url/" . $language . "/" . $row['id'] . "<br>";
}

```

And the output example:  

url/php/1/   

url/java/1/   

url/php/2/   

url/ruby/2/   

url/java/2/   

url/php/3/   

url/php/4/   

url/ruby/4/   

etc   

thank you very much
