How can I trigger errors on webpages so I can take a screen capture for visual display?-CodePudding

I want to be able to "make" browser display errors, like forbidden, 503 etc...

Is there some kind of sandbox where I could do this?

I need the errors to be rendered in google chrome, then take a screen capture of browser window.

Something like image under it, but force the browser to display something like this, maybe in Chrome dev tools could be done?

You can do this with try-catch condition and set_exception_handler function like this:

<?php

class MyCustomException extends Exception { }

function exception_handler($exception) {
   echo "Uncaught exception: " , $exception->getMessage(), "\n";
}

set_exception_handler('exception_handler');

try {
   throw new Exception('Uncaught Exception');
} catch (MyCustomException $e) {
   echo "Your custom exception caught ";
   echo $e->getMessage();
} finally {
   echo "I'm always here";
}

print "Not executed";

You can simply use try & catch, you can check function inside try and throw error to catch. For example i need to run mysql if is there any error report it..

So here is function for it

try{
if(!mysqli_query($conn,$query)){
   throw new Exception(you can put query error)
}
}catch(Exception $e){
 print_r($e)
}

the $e inside catch will give you erro
