filesize() returning false in php

manpreet Best Answer 3 years ago

i'm trying to make a jason of the files and there size, its working perfectly for the directory that this php file is saved in but when i change the directory the filesize() returns false. this works fine:

php
  header('Content-Type: application/json');
  $dir= "./"; //path
  $list = array(); //main array

if(is_dir($dir)){
   if($dh = opendir($dir)){
       while(($file = readdir($dh)) != false){

           if($file == "." or $file == ".."){
               //...
           } else { //create object with two fields
               $list3 = array(
               'file' => $file, 
               'size' => filesize($file));
               array_push($list, $list3);
           }
       }
   }

   $return_array = array('files'=> $list);
   echo json_encode($return_array);
}
?>

but this doesn't work:

php
 header('Content-Type: application/json');
  $dir= "Syllabus/Undergraduate Courses/BCA/Semester 1"; //path
  $list = array(); //main array

if(is_dir($dir)){
   if($dh = opendir($dir)){
       while(($file = readdir($dh)) != false){

           if($file == "." or $file == ".."){
               //...
           } else { //create object with two fields
               $list3 = array(
               'file' => $file, 
               'size' => filesize($file));
               array_push($list, $list3);
           }
       }
   }

   $return_array = array('files'=> $list);
   echo json_encode($return_array);
}
?>
