What alternative methods can be used in PHP to achieve similar functionality as the Readline module?

The Readline module in PHP provides functionality for interactive command line input. If the Readline module is not available or not enabled, alternative methods can be used to achieve similar functionality. One such method is using the `fgets()` function to read input from the command line. This function reads a line from the file pointer, which can be set to `STDIN` to read input from the command line.

// Alternative method to achieve similar functionality as Readline module using fgets()

// Read input from the command line using fgets()
echo "Enter your input: ";
$input = fgets(STDIN);

// Display the input
echo "You entered: " . $input;
