How can the foreach loop be used to iterate through all POST variables in PHP?

To iterate through all POST variables in PHP, we can use a foreach loop to loop through the $_POST superglobal array. This allows us to access each key-value pair of the POST data and perform any necessary operations on them. 

foreach ($_POST as $key => $value) {
    // Access each POST variable using $key and $value
    echo "Key: $key, Value: $value <br>";
}
