PHP use variable of class in other class - php

Question

I basically know php but i am new to all that classes-stuff. For now - love it.
Here is my problem:
I'm writing a class to do all that stuff around the account-managements. (e.g. create new account, get account details, check if account exists .... )
Within that class i need to do some MySQL-requests. Therefor i i'm using the medoo-class (http://www.medoo.in).
class acc{
// Attributes
public static $account;
public $pw;
protected $error;
public function acc_exist() {
$database = new medoo();
$acc_count = $database->count("table_accounts", ["column_account" => acc::$account]);
if ($acc_count == 0) {return true;} else {$this->error .= "Account exists already!";};
}};
Please note the line:
$database = new medoo();
and
$acc_count = $database->count("table_accounts", ["column_account" => acc::$account]);
here i bring in medoo. And ["column_account" => acc::$account] acctually works. As i read in some other posts, i made $accounts public static.
now i call my class like this:
$my_acc = new acc();
$my_acc->account = 'Luci';
$my_acc->acc_exist();
i need to work like that. Doing some acc($account) is difficult in context of the rest of my code.
But as i expected, i get an error:
Strict Standards: Accessing static property acc::$account as non static
clear to my that static holds the var's value. so i will need some other way. Anyone got an idea?
best, Lox

Answer 1

I don't think you need to have $account as static, that wouldn't make sense with the way you're probably going to be using this code, try having public $account; and then use ["column_account" => $this->account]
So:
class acc{
// Attributes
public $account;
public $pw;
protected $error;
public function acc_exist() {
$database = new medoo();
$acc_count = $database->count("table_accounts", ["column_account" => $this->account]);
if ($acc_count == 0) {return true;} else {$this->error .= "Account exists already!";};
}};

Answer 2

You are calling a variable that doesn't exist.
You declared $accout as public and static.
But you attempt calling $account.
Replace:
$my_acc->account = 'Luci';
With:
$my_acc->accout = 'Luci';

Answer 3

Vex is right. Take off the static keyword and use ["column_account" => $this->account] instead.
