What best practice can be followed to efficiently save the file on the server in PHP without using fopen?

To efficiently save a file on the server in PHP without using fopen, you can use the file_put_contents function. This function allows you to write data to a file in a single line of code, making it a more concise and efficient method compared to using fopen.

// Example code to save a file on the server using file_put_contents
$file = 'example.txt';
$data = 'Hello, World!';

if (file_put_contents($file, $data) !== false) {
    echo 'File saved successfully.';
} else {
    echo 'Error saving file.';
}
