Use php+mcDropdown to realize that the file path can be selected in the drop-down box_PHP tutorial

Recently used php to read file directory information, and got the following piece of code on the Internet:
//Get the file list in the specified directory
//$path specifies the directory, which defaults to the current Directory
//$ifchild Whether to display the subdirectory file list, not displayed by default
//$curpath Displays the current path, the default is to start from the current directory; this is mainly to display the determined href path

Copy code The code is as follows:

function openpath($path=".",$ifchild=false,$curpath=".")
{

$handle = opendir($path);
if($handle)
                                                                                                                        "..")
                                                                                                                                     🎜>                                                                                                                 { ifchild)//If the display subdirectory is set
                                                                                                       Y_SEPARATOR.$file,$ifchild,$curpath.DIRECTORY_SEPARATOR.$file);
                                       🎜>                                                                                                                       _blank">$filen";
                                                                                                                                                                                                                                                                                                       $file " target="_blank">$filen"; 🎜>                                                                                                                                                               echo $file; }
                                                                                                                                  
Because I want to provide the function of path selection, it is best to have a drop-down menu with the path to be selected, which is much more convenient, so I changed it myself and output the path into an unordered list.
The following is a code to obtain the paths of all sub-files under the current file:

Copy the code The code is as follows:

/ *Get the file path list of the specified directory
*$path specifies the directory, the default is the current directory
*$ifchild Whether to get the subdirectory file list, the default is not obtained
*$curpath displays the current path, the default is Starting from the current directory
*&$pach_html_srt passes a reference to an external variable. Because this method may be called recursively, saving some information in this way
* can also be achieved using global variables. Variable changes inside the function also affect the outside.
*&$path_ref_count The principle is the same as above, a counting flag. If it is recursive, the counter will increment from the last saved value
*/
function openpath($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($ifchild)
{
//Recursion
openpath($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 plug-in at the front desk to allow users to select the directory they want to enter through the drop-down menu, so it needs to be encapsulated into Specify the format:

Copy code The 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.' ul>';
$path_html_str = str_replace ( "
", '', $path_html_str );

In this way, I pass $path_html_str to the front desk and display it What comes out is an unordered list that meets the requirements of mcDropdown, and the corresponding candidate list can be displayed.
The complete code is as follows:
test.html

Copy the code The code is as follows:

Please select a category:

#categorymenu#

test.php

Copy code The code is as follows:

//Directory information processing
$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 ( "< ;ul>", '', $path_html_str );
//var_dump($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, $str_buffer ;
*$curpath displays the current path, starting from the current directory by default
*&$pach_html_srt passes a reference to an external variable, because this method may be called recursively, so save it in this way
* Some information can also be implemented using global variables. Changes in variables inside the function also affect the outside.
*&$path_ref_count The principle is the same as above, a counting flag. If it is recursive, the counter will increment from the last saved value
