The recent use of PHP file directory information read, online to get the following code:
Gets the list of files in the specified directory
$path The specified directory, default to the current directory
$ifchild whether to display a list of subdirectory files, which are not displayed by default
$curpath Displays the current path, which is the default starting from the current directory; This is primarily to show the determination of the HREF path
Copy CodeThe code is as follows:
function Openpath ($path = ".", $ifchild =false, $curpath = ".")
{

$handle = Opendir ($path);
if ($handle)
{
while (false!== ($file = Readdir ($handle)))
{
if ($file! = "." && $file! = "...")
{
$fullPath = $path. Directory_separator. $file;
if (Is_dir ($fullPath))//If it is a directory file
{
if ($ifchild)//If the display subdirectory is set
{
Recursive
Openpath ($path. Directory_separator. $file, $ifchild, $curpath. Directory_separator. $file);
}
Else
{
echo "
  • $file
  • \ n ";
    }
    }
    else if ($file! = basename (__file__))//Exclude Current execution script
    {
    echo "
  • $file
  • \ n ";
    }
    Else
    {
    Echo $file;
    }
    }
    }
    }
    Closedir ($handle);
    }

    Because you want to provide the function of path selection, it is best to have a drop-down menu, which is left to select the path to display, so much more convenient, so they changed, the path output into an unordered list.
    Here is a code that gets the path of all the child files under the current file:
    Copy CodeThe code is as follows:
    /* Get a list of specified directory file paths
    * $path The specified directory, default to the current directory
    * $ifchild whether to get a list of subdirectory files, which is not acquired by default
    * $curpath Displays the current path, which defaults to starting from the current directory
    *& $pach _html_srt to pass in a reference to an external variable, because this method might be called recursively, so save it in this way
    * Some information can also be implemented with global variables, and changes in the function internal variables also affect the external.
    *& $path _ref_count principle, a count flag, if recursive, the counter from the last saved value from the beginning of the increment
    */
    function Openpath ($path = ".", $ifchild =false,& $path _html_str,& $path _ref_count)
    {
    $handle = Opendir ($path);
    if ($handle)
    {
    while (false!== ($file = Readdir ($handle)))
    {
    if ($file! = "." && $file! = "...")
    {
    $fullPath = $path. Directory_separator. $file;
    if (Is_dir ($fullPath))//If the file is a directory
    {
    $path _html_str.= '
  • ';
    $path _html_str.= $file. '
      ';
      if ($ifchild)
      {
      Recursive
      Openpath ($path. Directory_separator. $file, $ifchild,& $path _html_str,& $path _ref_count);
      }
      $path _html_str.= '
  • ';
    }
    }
    }
    }
    Closedir ($handle);
    }

    With the above method, I can use the jquery Mcdropdown plugin in the foreground to allow the user to select the desired directory through the drop-down menu, so it needs to be encapsulated in the specified format:
    Copy CodeThe code is as follows:
    $path _ref_count = 1;
    $path _html_str = ";
    Openpath (".",true,& $path _html_str,& $path _ref_count);
    $path _html_str = '
        '. $path _html_str. '
    ';
    $path _html_str = Str_replace ("
      ",", $path _html_str);

      So I spread the $path_html_str to the foreground, showing a list of unordered lists that meet the requirements of mcdropdown, and you can display the corresponding list of options.
      The complete code is as follows:
      test.html
      Copy CodeThe code is as follows:




      <title>Test</title>










      Please select a Category:



      #categorymenu #



      test.php
      Copy CodeThe code is as follows:

      $path _ref_count = 1;
      $path _html_str = ";
      Openpath (".",true,& $path _html_str,& $path _ref_count);
      $path _html_str = '
          '. $path _html_str. '
      ';
      $path _html_str = Str_replace ("
        ",", $path _html_str);
        Var_dump ($path _info);
        Var_dump ($path _html_str);
        $str _buffer = file_get_contents (dirname (__file__). Directory_separator. ' test.html ');
        $str _buffer = Str_replace ("#categorymenu #", $path _html_str, $str _buffer);
        $str _buffer = Str_replace ("#delim #", Directory_separator, $str _buffer);
        echo $str _buffer;
        /* Get a list of specified directory file paths

        {
