如何通過用戶名爲用戶創建多個目錄

Question

這是我想讓它能夠通過用戶名爲用戶創建多個目錄的代碼。

現在它由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); 
    } 
?> 

名稱創建我想其他兩個目錄來這樣一個文件夾：

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

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

所有你需要做的是改變我給你以下的原始腳本：

<?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); 
    } 
?>

你已經有解決方案在這裏不你。繼續做你已經做什麼..

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

您需要創建用戶名的一個文件夾，比創建用戶名文件夾下的文件夾等根據自己的需要和那裏的訪問會類似。

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); 
}

通過你的結果只是循環，並創建目錄（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); 
     } 
    } 
}
