PHP: Copy a specified directory to another specified directory – Nesting

When a user needs to copy a specific directory to another specified directory, they can use the following PHP function:

function copyDirectory($src, $dst) {
    // 检查源目录是否存在并且是否是目录
    if (!is_dir($src)) {
        return false;
    }
 
    // 检查目标目录是否存在并且是否是目录
    if (!is_dir($dst)) {
        mkdir($dst);
    }
 
    // 打开源目录
    $dirHandle = opendir($src);
 
    // 循环读取源目录下的文件和目录，复制到目标目录
    while (false !== ($file = readdir($dirHandle))) {
        if ($file != "." && $file != "..") {
            $srcFile = $src . "/" . $file;
            $dstFile = $dst . "/" . $file;
 
            if (is_dir($srcFile)) {
                copyDirectory($srcFile, $dstFile); // 递归复制子目录
            } else {
                copy($srcFile, $dstFile);
            }
        }
    }
 
    closedir($dirHandle);
 
    return true;
}
