How can you filter $_POST data in PHP to exclude specific values like submit buttons?

When working with form submissions in PHP, the $_POST superglobal contains all the data sent from the form, including submit buttons. To filter out specific values like submit buttons, you can use the array_filter() function along with a callback function that excludes the values you don't want. This allows you to only keep the form data you need for processing. 

// Filter out specific values like submit buttons from $_POST data
$filteredData = array_filter($_POST, function($value) {
    return !is_string($value) || $value !== 'Submit';
});
