如何通过用户名为用户创建多个目录

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。

现在它由big

<?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); 
    } 
?> 

名称创建我想其他两个目录来这样一个文件夹：

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

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

所有你需要做的是改变我给你以下的原始脚本：

<?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); 
    } 
?>

你已经有解决方案在这里不你。继续做你已经做什么..

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

您需要创建用户名的一个文件夹，比创建用户名文件夹下的文件夹等根据自己的需要和那里的访问会类似。

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); 
}

通过你的结果只是循环，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); 
     } 
    } 
}
