PHP - File Handling

How can you safely delete a directory temp and all its contents (files and subdirectories) in PHP?

AUse rmdir('temp') directly to delete everything

BUse scandir() and ignore deleting files, just remove directory

CUse unlink('temp') to delete the directory and contents

DWrite a recursive function to delete all files and subdirectories, then remove the directory

Step-by-Step Solution

Solution:

Step 1: Understand rmdir() and unlink() limitations
rmdir() only removes empty directories; unlink() deletes files, not directories.
Step 2: Use recursion to delete contents first
To delete all contents safely, recursively delete files and subdirectories before removing the directory.
Final Answer:
Write a recursive function to delete all files and subdirectories, then remove the directory -> Option D
Quick Check:

Quick Trick: Delete directory contents recursively before rmdir() [OK]
