PHP之目录 php php 目录操作 php mkdir 多级目

目录操作

• 新建目录
  mkdir(路径，权限，递归创建)
• 删除目录
  rmdir()
• 移动（改名）
  rename()
• 获取目录内容
  //打开目录
  目录句柄 = opendir()
  //读取目录
  文件名 = readdir(目录句柄)
  依次读取文件名，同时向下移动文件句柄指针，读取不到则返回false
  //关闭目录
  closedir()

递归读取目录内容

<code><span><?php </span>
showDir(<span>'../../file'</span>);
<span><span>function</span><span>showDir</span><span>(<span>$path</span>,<span>$dep</span>=<span>0</span>)</span>{</span><span>$pos</span> = opendir(<span>$path</span>);
    <span>while</span>(<span>false</span>!==<span>$file</span>=readdir(<span>$pos</span>)){
        <span>if</span>(<span>$file</span>==<span>'.'</span>||<span>$file</span>==<span>'..'</span>) <span>continue</span>;
        <span>echo</span> str_repeat(<span>"&nbsp"</span>,<span>$dep</span>*<span>4</span>),<span>$file</span>.<span>''</span>;
        <span>if</span>(is_dir(<span>$path</span>.<span>'/'</span>.<span>$file</span>)){
            <span>$func</span> = <span>__FUNCTION__</span>;
            <span>$func</span>(<span>$path</span>.<span>'/'</span>.<span>$file</span>,<span>$dep</span>+<span>1</span>);
        }
    }
}</span></code>

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });
