Are you able to choose who your PCI compliance is verify through?: Yes and No. It depends what gateway account the company is using. All of these PCI standards are based on the volume of transactions. For companies that have a lot of transactions, there is a higher level of compliance that is required. A large (gateway) company they will typically contract out a company to handle these test and you need to verify compliance through them. The smaller companies (some banks provide gateways) only require a self-assessment which can be completed in about 5 minutes online. This assessment is also contracted out to third-party companies.

Once your client has become PCI compliant, they will no longer be charged the extra fee. The PCI compliance should also be built into the gateway fees, there should not be an extra charge to your client for this service.

The IN operational statement let’s you match on a list of values in a clause. The implode statement will turn the array (shown below) into a string.

<?php
	if (isset($_POST['doSave'])){
 		if (isset($_POST['checkbox'])){
			$doSave = implode(',',$_POST['checkbox']);
			//if checkbox IS checked, update the database with a value of 1
			 $updatequery = "update databasename set checkbox='1' where id IN ($doSave)";
			 mysql_query($updatequery) or die(myql_error());
			//if checkbox IS NOT checked, update the database with a value of 0
			 $updatequery2 = "update databasename set checkbox='0' where id NOT IN ($doSave)";
			 mysql_query($updatequery2) or die(myql_error());}
		if (!isset($_POST['checkbox'])){
			//if checkbox IS NOT set, update the database with a value of 0
			 $doSave = implode(',',$_POST['checkbox']);
			 $updatequery2 = "update databasename set checkbox='0' where id NOT IN ($doSave)";
			 mysql_query($updatequery2) or die(myql_error());}
