Sample Parsing of Returned Key-Value Pairs from PHP Query Strings
The following PHP snippet fully parses the returned key-value pairs from Direct Post Handler query string and assigns it to an array called $output. Note that the $_REQUEST super global variable is not used in favor of directly parsing $_SERVER[QUERY_STRING] since $_REQUEST may contain extraneous information that is not needed.
<?php
parse_str( $_SERVER[QUERY_STRING], $output );
?>
Sample Parsing of Output with Errors Returned
Below is a sample array structure of the parse where errors were returned. In this particular case, the end-user selected credit card as form of payment, but failed to fill out the credit card fields.
