PHP - File Handling

Consider this PHP code snippet:

$dir = 'testdir';
if (mkdir($dir)) {
  echo 'Created';
} else {
  echo 'Failed';
}
rmdir($dir);

What is the main issue if the directory testdir already exists?

Amkdir() will fail and echo 'Failed', and rmdir() will fail to remove the directory

Bmkdir() will fail and echo 'Failed', but rmdir() will still remove the directory

Cmkdir() will fail and echo 'Failed', and rmdir() will remove the directory anyway

Dmkdir() will overwrite the existing directory

Step-by-Step Solution

Solution:

Step 1: Behavior of mkdir() when directory exists
If testdir already exists, mkdir() returns false and echoes 'Failed'.
Step 2: Behavior of rmdir() on existing directory
Since the directory exists, rmdir() will attempt to remove it. If the directory is empty and permissions allow, it will succeed. Otherwise, it will fail.
Final Answer:
mkdir() will fail and echo 'Failed', but rmdir() will still remove the directory -> Option B
Quick Check:
mkdir() fails if exists; rmdir() removes empty directory [OK]

Quick Trick: mkdir() fails if folder exists; rmdir() needs empty folder [OK]
