Question

这是我想让它能够通过用户名为用户创建多个目录的代码。

现在它只创建一个名为big

的文件夹

<?php
    $db = new PDO("..."); // Connection details here
    $stmt = $db->prepare("SELECT * from some_table where user_id = :id"); // Finds the information based on an ID. Change this depending on how you want the select to work
    $stmt->execute(array(':id' => "1")); // Gives value to :id and executes the statement
    $row = $stmt->fetch();

    // Then run your code

    if (!file_exists(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/big')) {
        mkdir(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/big', 0777, true);
    }
?>

我想要另外两个这样的目录：

user/upload/'.$row['UserName'].'/avatar/small

user/upload/'.$row['UserName'].'/avatar/original

Answer 1

你已经有了解决方案。继续做你正在做的事情......

if( !is_dir( (ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/big' ) ){
    mkdir(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/big', 0777, true);
}

if( !is_dir ( (ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/big' ) ){
    mkdir(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/big', 0777, true);
}

等等

只需遍历结果并创建目录（is_dir比file_exists更快）

$db = new PDO("..."); // Connection details here
$stmt = $db->prepare("SELECT * from some_table where user_id = :id"); // Finds the information based on an ID. Change this depending on how you want the select to work
$stmt->execute(array(':id' => "1")); // Gives value to :id and executes the statement

// Then run your code
while ($row = $stmt->fetch()) {

    array_walk(array('big', 'small', 'original'), function(&$v, $k) {   
        $dir = ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/' . $v;
        if (!is_dir($dir)) {
            mkdir($dir, 0777, true);
        }
    }
}

Answer 3

您需要创建一个用户名的单个文件夹，然后根据需要在用户名文件夹下创建其他文件夹，并且访问权限类似。

if (!file_exists(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/big')) {
    @mkdir(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/big', 0777, true); 
}
if (!file_exists(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/small')) {
    @mkdir(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/small', 0777, true);
}
if (!file_exists(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/original')) {
    @mkdir(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/original', 0777, true);
}

您需要做的就是修改我给您的原始脚本：

<?php
    $db = new PDO("..."); // Connection details here
    $stmt = $db->prepare("SELECT * from some_table where user_id = :id"); // Finds the information based on an ID. Change this depending on how you want the select to work
    $stmt->execute(array(':id' => "1")); // Gives value to :id and executes the statement
    $row = $stmt->fetch();

    // Then run your code

    if (!file_exists(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/big')) {
        mkdir(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/big', 0777, true);
    }

    if (!file_exists(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/small')) {
        mkdir(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/small', 0777, true);
    }

    if (!file_exists(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/original')) {
        mkdir(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/original', 0777, true);
    }
?>
