与他们的用户名在PHP

Question

我想创建一个由自己的用户名每个用户目录中创建用户目录，我写了这个代码

<?php 
if (!file_exists(ROOT_PATH.'user/upload/[User Name]/avatar/big')) { 
    mkdir(ROOT_PATH.'user/upload/[User Name]/avatar/big', 0777, true); 
} 
?> 

我想与用户更换[用户名]用户名。

在我的MySQL数据库用户名列名。

这是web.config.php文件内容

像这样的东西是你所追求的。它会给你足够的信息来上手，但是你需要考虑建立new PDO部分并修改查询，以匹配你在找什么：

<?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); 
    } 
?>
