I’m trying to check if a user is a guest within a view and I tried this:
<?php
use Yii;
//........
?>
//....
<?php if (!Yii::$app->user->isGuest) : ?>
//......
<?php endif; ?>
…every time I refreshed the page Apache would crash.
So then I removed the use statement and did this instead:
<?php if (!\Yii::$app->user->isGuest) : ?>
//......
<?php endif; ?>
…and it worked fine.
Do you realize that its php statement and ought to be in <?php ?>
Sorry, yes it was within one. I have updated my post to reflect this.
put error message too. Its too important to be hidden!
I’m using Xampp locally (this is my dev environment) and there isn’t anything too specific in the logs. Here is what is logged when the error happens:

I didn’t mean server log but rather error you on your browser
There is no error. What I get is a Windows popup window that basically says "Apache HTTP Server has encountered a problem and needs to close. We are sorry for the inconvenience." then I have the option of sending an error report to Windows or not.
Once I close it, the page stalls for awhile longer and then can’t be resolved. At that point I have to restart Apache.
Mhh! Strange! Did you try WAMP just in case its XAMMP failing to report error correctly?
Its silly suggestion but well, I cant think of anything else!
Naa… haven’t tried it as not too worried about it since it works normally with the workaround I used; just thought I would mention it.
Your logs are in ‘runtime’ dir. Check that YII_DEBUG is set to true to display errors.
I would assume this is an Apache error that Yii is causing somehow so thought it should be in Apaches logs? But either way, nothing was logged in the Yii logs.
There won’t be anything in apache’s log, unless Yii throws http exception explicitly. It should give you php warning, because the statement
makes no sense.
Debugging will help you, it is quite hard to develop an app blindfold.
What do you mean it makes no sense?
Classes from global space (e.g Yii class) are available in any namespace, they don’t have to be imported with ‘use’.
That’s not true. Since I wasn’t using a namespace in the view I didn’t need to use it, however you do need to do:
use Yii;
inside other files where you are in a different namespace.
Sorry, I mislead you, this needs an explanation. Technically, view file is yii\web\View (it is included from its method). Because of the way php treats inheritance in includes, $this is there but otherwise it doesn’t behave itself like it is object scope. Treat it like it is global space, so no ‘use’ of un-namespaced classes. Btw,
use Yii as Yii;
would be useless there also, but give no warning, that’s a known vagary of php.
