What are some potential solutions for waiting for user input in a PHP script?

One potential solution for waiting for user input in a PHP script is to use the `fgets()` function to read input from the standard input stream. This function will wait for the user to input data before continuing with the script execution. 

<?php
echo "Please enter your input: ";
$userInput = fgets(STDIN);
echo "You entered: " . $userInput;
?>
