500th file_get_contents response. How to decide?

Question

PHP

Hello. I can not understand the cause of the problem: I write

file_get_contents(" http://non-existent.ru/ ");

and get 500 error (Internal Server Error).
If the url exists, then no error occurs. Where to dig?
On the other server, everything is fine and the error is knocked out as standard

Warning: file_get_contents( http://defunct.ru/): failed to open stream: HTTP request failed! in /var/www/user/data/www/dsdsdsds/_test.php on line 5

Answer 1

Enable error reporting?

Answer 2

Check what exists?

Answer 3

Answer 4

Try like this.

$options = [
    'ignore_errors' => true
];
$context = stream_context_create($options);
$file = file_get_contents('http://someurl.com', false, $context);

Answer 5

Hello!
Can't handle Internal Server Error.
I get this:
stream_context_create(): options should have the form ["wrappername"]["optionname"] = $value

Answer 6

$('#test1, #test2, #nature_test1, #nature_test2, #animals_test').hide();

Answer 7

$('.what-i-need-hide').hide()

Answer 8

If your ID`s are strictly in order, as in the example, then loop through the interval from and to. If not, form an array of elements to hide / open, passing through it in the future.
This will shorten the code.

Answer 9

But you can’t apply one class to all of them with handles, hide by class and open by id? If not, why not?)
