PHP directory php php directory operation php mkdir multi-level directory

Directory operation

• Create new directory
  mkdir (path, permissions, recursive creation)
• Delete directory
  rmdir()
• Move (rename)
  rename()
• Get directory content
  //Open directory
  Directory handle = opendir()
  //Read directory
  File name = readdir(directory handle)
  Read the file names in sequence and move the file handle pointer downward at the same time. If it cannot be read, it returns false
  //Close directory
  closedir()

Recursively read directory contents

<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>'</br>'</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>);
        }
    }
}</code>

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

The above has introduced the PHP directory, including PHP and directory content. I hope it will be helpful to friends who are interested in PHP tutorials.
