Can you provide examples of PHP functions or methods that can be used to manipulate text files efficiently?

To efficiently manipulate text files in PHP, you can use functions like file_get_contents() to read the contents of a file, file_put_contents() to write data to a file, fopen() and fwrite() for more advanced file handling operations, and fgets() to read a single line from a file. These functions allow you to easily read, write, and manipulate text files in PHP. 

// Example of reading a text file using file_get_contents()
$file_contents = file_get_contents('example.txt');
echo $file_contents;

// Example of writing to a text file using file_put_contents()
$data = "Hello, World!";
file_put_contents('example.txt', $data);

// Example of reading a text file line by line using fgets()
$file = fopen('example.txt', 'r');
while (!feof($file)) {
    $line = fgets($file);
    echo $line;
}
fclose($file);
