File read problem (Line by line )

[imrantbd]

Hi,
I am facing problem to read file. The file content is following :

dir1
dir2
dir3
dir4

I read the file and put all the data in an array like below
array_data[1] = dir1
array_data[2] = dir2
array_data[3] = dir3
array_data[4] = dir4

But when I want to open the all the directory by following way I can open only last directory(dir4).What can I do to open all directory?

for($a=0; $a<=3; $a++)
     {
         $file2 = array_data[$a];   
         $TrackDir2 = opendir($file2);      
              $j = 0;
         while ($file3 = readdir($TrackDir2)) { 
               if (filetype($file3) != "dir" && $file3 != "." && $file3 != ".." ) 
               { 
                     $fileinfo = pathinfo($file3);
                     $extension = $fileinfo["extension"];
 
                     if($extension=="txt")
                     {
                             echo $txt_file_name = $file3;
                         $filen2 = $fdata[$a]."/".$txt_file_name;
                         $filestring = fopen($filen2,'r');
                         $filecont = fread($filestring,200); 
                         fclose($filestring);
 
                     }
 
                }
 
         } 
 
         ?>    
         <tr><td>
         <?
         echo $filecont;
         ?>
         </td></tr>     
             <?     
     }

Thank to all advanced.

array_data is not a valid PHP variable name. Do you have $array_data or array_data?

You are saving the path at index 1 i.e. "array_data[1] = dir1" but in for() loop, you are fetching the data from array_data[0].

Please post the exact code here.


There may be a problem in opening a dir i.e. $TrackDir2 = opendir($file2);
Put echo before this line and see what is the value for $file2;
