What is the difference between is_dir() and file_exists() functions in PHP?

The difference between `is_dir()` and `file_exists()` functions in PHP is that `is_dir()` specifically checks if a given path is a directory, while `file_exists()` checks if a file or directory exists at a given path. Therefore, `is_dir()` will return true only if the path points to a directory, while `file_exists()` will return true for both files and directories. 

// Check if a directory exists
$directoryPath = '/path/to/directory';
if(is_dir($directoryPath)){
    echo 'Directory exists';
} else {
    echo 'Directory does not exist';
}

// Check if a file or directory exists
$filePath = '/path/to/file_or_directory';
if(file_exists($filePath)){
    echo 'File or directory exists';
} else {
    echo 'File or directory does not exist';
}
