PHP - File Handling

What will be the output of the following PHP code?

$dir = 'myfolder';
if (is_dir($dir)) {
  $handle = opendir($dir);
  while (($file = readdir($handle)) !== false) {
    echo $file . ' ';
  }
  closedir($handle);
} else {
  echo 'Directory not found';
}

ASyntax error

BOnly files inside 'myfolder' without '.' and '..'

CDirectory not found

DList of all files and folders inside 'myfolder' including '.' and '..'

Step-by-Step Solution

Solution:

Step 1: Check if directory exists
The code uses is_dir() to check if 'myfolder' exists. If it does, it proceeds to open it.
Step 2: Read directory contents with readdir()
The readdir() function reads all entries including special entries '.' (current directory) and '..' (parent directory). These are echoed with spaces.
Final Answer:
List of all files and folders inside 'myfolder' including '.' and '..' -> Option D
Quick Check:
readdir() lists all entries including '.' and '..' [OK]

Quick Trick: readdir() returns '.' and '..' entries by default [OK]

Common Mistakes:

Assuming '.' and '..' are excluded automatically
Not checking if directory exists before reading
Forgetting to close directory handle
