How can the explode() function be used to separate form input in PHP?

The explode() function in PHP can be used to separate form input that is submitted as a string with a specific delimiter. For example, if a form input field allows users to enter multiple values separated by commas, explode() can be used to split the input into an array of individual values. This can be useful for processing and manipulating the form data in the backend. 

// Example of using explode() function to separate form input
$input = $_POST['values']; // Assuming 'values' is the name attribute of the form input field
$values_array = explode(',', $input);

// Now $values_array contains an array of individual values entered in the form input field
foreach($values_array as $value) {
    echo $value . "<br>";
}
