Initiate variable only once in php - even if another class extends it

[tino]

I have a class called logit, please excuse the incorrect formatting.

<? 

class logit

var: $logs=array();

// ... does other stuff ... 

?>

Now I have another class that extends logit

<? 

class lognot extends logit

if (!in_array($this->logs)) {
array_push($this->logs,$somevariable)
}

?>

Now I have another function that extends logit. Which I call after lognot

<?

class lognew extends logit

if(count($this->logs)<1) {
// do something
}
?>

Now I'm running into a problem where it resets $logs when lognew is called.

So I need $logs to be defined as a array on the first instance and for it then to not be initiated after, and to hold what ever values the class's that extend logit enter into this array. The final class lognew will then handle it all if it contains any data.

Thanks for any replies.

Can't you just check what $logs contains before deciding if you want to initialize it or not? Please use the code tag next time.

Apologies I thought I had used the code tag. Edited the original post now.

As I set it as the top of $logs as a var it doesn't seem to want to let me check to see if that variable is empty or doesn't have any data.

I'm probably doing something really stupid or missing some very simple point.

What the heck does that mean?

It means that it initiates the $logs as an array(); every time I call a class that extends this one.

If I do a check before, then it will create a syntax error as its at the start of the class.

Why not initialize it in the constructor?

Thanks, I hadn't thought of that.
