What are the differences between using fwrite() and fputs() in PHP for writing to a text file?

When writing to a text file in PHP, the main difference between fwrite() and fputs() is that fwrite() allows you to specify the length of the data to write, while fputs() does not. If you need to write a specific number of bytes to a file, fwrite() is the better choice. However, if you are simply writing strings to a file, fputs() is a simpler and more straightforward option.

// Using fwrite() to write a specific number of bytes to a file
$file = fopen("example.txt", "w");
$data = "Hello, World!";
$length = strlen($data);
fwrite($file, $data, $length);
fclose($file);

// Using fputs() to write a string to a file
$file = fopen("example.txt", "w");
$data = "Hello, World!";
fputs($file, $data);
fclose($file);
