Does not getting yii\base\ErrorException in local server,but error returns from live

Yii 2.0
1

Do not get errors like “yii\base\ErrorException: Trying to access array offset on the value of type null” in the yii2 local server. But live server return error. How do I configure the environment setting to get all errors for yii2?

Different php versions?

Without seeing the relevant code, it will be hard to say for sure. May be as @InsaneSkull said, it is a code that depends on some functionality that behaves different among different PHP versions. Or it might be environment dependent code… or anything else!

What does this mean?
Could you show us the code that produces this error?

Hi,
Here is my code that returns the error “Trying to access array offset on the value of type null”

if($roomExists[‘id’] > 0){
}

But the error doesn’t show on the local server

When I used
!empty($roomExist),
the error disappeared in the live site.

Thanks & Regards

you should use this check and your error may be because of different data that will be sometimes empty

Your code lacks context. But what it means is that by the time that line is reached, $roomExists is already null. If that is not expected debug your code
