php - Selecting file to be edited -

i have application used edit .txt files. application made of 3 parts

1. displays contents of folder files edited(each file link when clicked opens on edit mode).

2. writing in file.

3. saving file.

part 2 , 3 have completed using fopen , fwrite functions wasn't hard. part need part 1 open file inputing location , file name in php file have display function , save function:

$relpath = 'file_to_edit.txt'; $filehandle = fopen($relpath, 'r') or die("failed open file $relpath ! "); 

but want file open in edit mode when clicked instead of typing in files name every time.

$directory = 'folder_name';  if ($handle = opendir($directory. '/')){     echo 'lookong inside \''.$directory.'\'<br><br>';          while ($file = readdir($handle)) {         if($file !='.' && $file!='..'){         echo '<a href="'.$directory.'/'.$file.'">'.$file.'<a><br>';      }      }  } 

this code ti use display list of files in specified folder. can give me pointers how can achieve ? appreciated.

1. to content of file use file_get_contents();
2. to put content of file use file_put_contents(); file_append flag editing.
3. to recieve list of files in directory can use directoryiterator

example:

foreach (new directoryiterator('path/') $fileinfo) {     if($fileinfo->isdot()) continue;     echo $fileinfo->getfilename() . "<br>\n"; } 

if don't want put filenames can put read files once put in db assign ids them , use links id param. other solution store files in session array , assign keys them. when want file need provide key instead of whole filename , path.

example $_session

$file_arr = array(); foreach (new directoryiterator('path/') $fileinfo) {     if($fileinfo->isdot()) continue;     $file_arr[] = array("path" => $fileinfo->getpathname(), 'name' => $fileinfo->getfilename()); } $_session['files'] = $file_arr; 

then in view can use

foreach($_session['files'] $k=>$file) {   echo "<a href='edit.php?f=".$k."'>'.$file['name'].'</a>"; } 

and edit.php

$file = (int)$_get['f'];  if(array_key_exits($file, $_session['files']) {    $fileinfo = $_session[$file'];     //in file info have $fileinfo['path'] $fileinfo['name'] }
