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 = 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 = ";

$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;
