Object ISSET

Copy linkTweet thisAlerts:
Feb 01.2022

So I want to check if my object has been created.

I’d have thought

`if (isset($myObject)){ }`

Would have done the trick but you can’t. What’s the ‘best practice’ way of doing something like this?

@NogDogFeb 01.2022 — Assuming you want to make sure it's a particular type of object, maybe...
[code=php]
if(isset($myObject) and $myObject instanceof SomeClassNameHere) { }
[/code]
If all you care is that it's _any_ type of object, you could replace the instanceof expression with an [u][is_object()](https://www.php.net/manual/en/function.is-object.php)[/u] call instead, I suppose.

@NogDogFeb 01.2022 — PS: If you just want to make sure an object creation worked:
[code=php]
$foo = new Something();
if(empty($foo)) {
throw new Exception("Oops");
}
[/code]
(Though there's a good chance it will have already thrown an Exception, I suspect?)

@kiwisauthorFeb 01.2022 — Sorry, I've just realized. When I create the object. I simply pass in a database so it'll always be created.

I populate all the properties by calling a method loadFromID

I pass in a ID which relates to a a database ID.

I need to check if something has been returned and properties populated or not.

Success!
