_POST array & remove NULL values from list

[sharp.mac]

Ok, so I got a php loop going on that creates several input fields. What I am using as the naming sequence is as follows.

<input name="clientPickup<?php echo $row_count; ?>" type="text" id="clientPickup<?php echo $row_count; ?>" style="width:350px;"/>

 

on the submitted page the php catch looks like

foreach($_POST as $k=>$v) $$k=$v;

 

Now I understand that I am now allowed to call my variables as simply as $clientPickup1, $clientPickup20, $clientPickup90, etc....

 

This is cool, but I never know what the $clientPickupNUMBER is! Sometimes its...

 

clientPickup5,

clientPickup12,

clientPickup34,

clientPickup98

 

Always different to say the least.

 

How can I run a loop that strips out all NULL values and rebuilds a new array that I can structure?

 

I've looked into array_filter, empty(), isset() and I simply do not understand what I am doing wrong.  Thank you for any advice you may have.

<input type="text" name="clientPickup[<?php print $row_count; ?>]" id="clientPickup<?php print $row_count; ?>" style="width: 350px;" />

 

foreach ($_POST['clientPickup'] as $row_count => $value) {
