PHP use variable of class in other class

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

You have a typo in the code $accout should be $account I think — RST

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!";};
}};

thx for your answer. Sorry but that won't work. The line $database->count("table_accounts", ["column_account" => $this->account]); refers to $database als object of medoo-class. That means, if you go with $this->account, you would call for a var $account in the medoo-class and not in the acc-class. That is the problem

Did you try the code? You're calling a method count of the $database object (which is of the medoo class), and you're passing parameters to the method, the first is a string, the second is an associative array, with a key value pair, the value being the account property of the current object $this (which is of the acc class). It should work.

hmm... that sounds very logical. wait a minute. i'll try again. maybe i mixed up something else.

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';

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

Bests,
