How can PHP file functions like fopen(), fwrite(), and fclose() be used effectively for writing and reading data to and from text files?

To effectively write and read data to and from text files using PHP file functions like fopen(), fwrite(), and fclose(), you can follow these steps: 1. Open a file using fopen() with the appropriate mode (e.g., 'w' for writing or 'r' for reading). 2. Use fwrite() to write data to the file or fgets() to read data from the file. 3. Close the file using fclose() to free up system resources. 

// Writing data to a text file
$file = fopen("data.txt", "w");
fwrite($file, "Hello, World!");
fclose($file);

// Reading data from a text file
$file = fopen("data.txt", "r");
$data = fgets($file);
fclose($file);

echo $data; // Output: Hello, World!
