What resources or functions in PHP can be used to handle file operations efficiently?

To handle file operations efficiently in PHP, you can use functions like fopen(), fclose(), fwrite(), and file_get_contents(). These functions allow you to open, read, write, and close files respectively. Additionally, using file handling modes like 'r', 'w', 'a', 'r+', 'w+', and 'a+' can help you perform specific file operations efficiently. 

// Example of opening a file, writing to it, and closing it
$file = fopen("example.txt", "w");
fwrite($file, "Hello, World!");
fclose($file);
