PHP also should throw a notice when you try to use reserved variables, like, $_POST, $_GETand $_COOKIE with "Illegal offset".

From your question, seems like you do not understand the difference between function parameters and arguments. You're already passing an argument, while it should be a parameter.

This:

function __construct($_POST){
    $this->customer       = trim($_POST['customer']);
    $this->CreateDate   = date('Y/m/d');    
}

Should be rewritten as:

function __construct($POST){
    $this->customer       = trim($POST['customer']);
    $this->CreateDate   = date('Y/m/d');    
}

And then:

$object = new YourClass($_POST);
