What PHP functions can be utilized to handle arrays and text file operations efficiently?

To handle arrays and text file operations efficiently in PHP, you can use functions like `file_get_contents()`, `file_put_contents()`, `explode()`, `implode()`, `json_encode()`, and `json_decode()`. These functions allow you to read/write data from/to text files, manipulate arrays, and convert data between arrays and JSON format. 

// Read data from a text file into an array
$file_contents = file_get_contents('data.txt');
$data_array = explode("\n", $file_contents);

// Manipulate the array
$data_array[] = 'New data';
$data_string = implode("\n", $data_array);

// Write data back to the text file
file_put_contents('data.txt', $data_string);

// Convert array to JSON format
$json_data = json_encode($data_array);

// Convert JSON back to array
$decoded_data = json_decode($json_data, true);
