Insert multiple entries into multiple tables

[rondog]

I have a form where a user can duplicate part of a form like below:

 

I've named the fields with the HTML arrays (ie. "fieldName[]") and came up with this:

	//--> CONTROLLERS
	$system_controllers_qty			= $_POST['system_controllers_qty'];
	$system_controllers_make		= $_POST['system_controllers_make'];
	$system_controllers_model		= $_POST['system_controllers_model'];
	$system_controllers_serial_no	        = $_POST['system_controllers_serial_no'];
	for ($i = 0; $i < count($system_controllers_qty); $i++)
	{
		echo "qty " . clean($system_controllers_qty[$i]) . "<br/>";
		echo "make " . clean($system_controllers_make[$i]) . "<br/>";
		echo "model " . clean($system_controllers_model[$i]) . "<br/>";
		echo "serial_no " . clean($system_controllers_serial_no[$i]) . "<br/>";
	}

	//--> CPUS
	$system_cpus_qty			= $_POST['system_cpus_qty'];
	$system_cpus_model			= $_POST['system_cpus_model'];
	$system_cpus_serial_no			= $_POST['system_cpus_serial_no'];
	$system_cpus_speed			= $_POST['system_cpus_speed'];
	for ($i = 0; $i < count($system_cpus_qty); $i++)
	{
		echo "qty " . clean($system_cpus_qty[$i]) . "<br/>";
		echo "model " . clean($system_cpus_model[$i]) . "<br/>";
		echo "serial_no " . clean($system_cpus_serial_no[$i]) . "<br/>";
		echo "speed " . clean($system_cpus_speed[$i]) . "<br/>";
	}

	//--> DISKS
	$system_disks_qty			= $_POST['system_disks_qty'];
	$system_disks_make			= $_POST['system_disks_make'];
	$system_disks_model_no			= $_POST['system_disks_model_no'];
	$system_disks_size			= $_POST['system_disks_size'];
	$system_disks_serial_no			= $_POST['system_disks_serial_no'];
	for ($i = 0; $i < count($system_disks_qty); $i++)
	{
		echo "qty " . clean($system_disks_qty[$i]) . "<br/>";
		echo "make " . clean($system_disks_make[$i]) . "<br/>";
		echo "model_no " . clean($system_disks_model_no[$i]) . "<br/>";
		echo "size " . clean($system_disks_size[$i]) . "<br/>";
		echo "serial_no " . clean($system_disks_serial_no[$i]) . "<br/>";
	}

	//--> MEMORY
	$system_memory_qty			= $_POST['system_memory_qty'];
	$system_memory_serial_no		= $_POST['system_memory_serial_no'];
	$system_memory_manf			= $_POST['system_memory_manf'];
	$system_memory_part_no			= $_POST['system_memory_part_no'];
	$system_memory_size			= $_POST['system_memory_size'];
	for ($i = 0; $i < count($system_memory_qty); $i++)
	{
		echo "qty " . clean($system_memory_qty[$i]) . "<br/>";
		echo "serial " . clean($system_memory_serial_no[$i]) . "<br/>";
		echo "manf " . clean($system_memory_manf[$i]) . "<br/>";
		echo "part_no " . clean($system_memory_part_no[$i]) . "<br/>";
		echo "size " . clean($system_memory_size[$i]) . "<br/>";
	}

 

This just outputs all the fields I post at the moment. Say I have 3 different disk types, it's going to loop 3 times. Is it possible to make this all into 1 giant query or am I better off doing each query separately? Each section is a different table.
