Question

我有这个问题，我想在这个目录数组中使用opendir，这有可能吗？使用固定网址，我可以使用readdir读取文件。但我不知道如何处理多个目录...
创建数组：

$results = mysqli_query($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>";
}

输出示例：
url / php / 1 /
url / java / 1 /

url / php / 2 /
url / ruby / 2 /
url / java / 2 /

url / php / 3 /

url / php / 4 /
url / ruby / 4 /
等

非常感谢你

Answer 1

foreach($resultsArray as $language => $array){
    foreach(array_slice(glob('work/'.$language.'/'.$rowtest['id'].'/*.jpg'),0,1) as $image){    
        echo $image . "<br />";
    }
}

您可以在foreach循环中一个接一个地读取目录。究竟是什么问题？

带有数组目录的PHP opendir和readdir（不是一个）
