大家好，PHP新手一直在尝试使用代码的复制和粘贴来构建一个应用程序（不要讨厌我），并根据我的需要进行定制，但我遇到了麻烦。用这种方式做事的问题是很难得到充分的理解。这就是问题所在。我正在将一个文件从一个目录复制到另一个目录，在此过程中对其进行重命名。然而，我想从源文件中复制一个文件（这很好），然后把它放在一个名为users的文件夹中。尝试了几个不同的选项，但却出现了错误。感谢您的帮助。

这就是功能代码。
<?php
// This source code is copied from http://php.net/manual/en/function.copy.php
// Real author of this code is gimmicklessgpt at gmail dot com
function recurse_copy($src,$dst) { // recursive function that copy files from one directory to another
$dir = opendir($src);
@mkdir($dst);
while(false !== ( $file = readdir($dir)) ) {
if (( $file != '.' ) && ( $file != '..' )) {
if ( is_dir($src . '/' . $file) ) {
recurse_copy($src . '/' . $file,$dst . '/' . $file);
}
else {
copy($src . '/' . $file,$dst . '/' . $file);
}
}
}
closedir($dir);
//echo "$src";
}
?>
不要认为配置文件包含任何会改变副本目的地的内容，所以不包括这些内容。
我看到两个问题。第一个是如何调用函数：
mkdir(dirname(__FILE__)."/users/"."$username"); // Create Directory
recurse_copy($SourceDir,$username); // Copy files from source directory to target directory
应为：
// Create Directory
mkdir(dirname(__FILE__)."/users/"."$username");
// Copy files from source directory to target directory; the one you just created
recurse_copy($SourceDir,dirname(__FILE__)."/users/"."$username");
第二个是函数中的@mkdir($dst);。您应该更改逻辑，只创建原始目标的子目录。
