EngineException not catch

[rick645]

First of all

$ php -v
PHP 8.1.2-1ubuntu2.13 (cli) (built: Jun 28 2023 14:01:49) (NTS)

Interestingly, in PHP7, we can expect to see exceptions in the engine itself which should allow us to solve this problem like this:
try {
    $result = file_get_contents($url);
} catch (EngineException $e) {
    // do something with $e
}

Let's try...

try {
    file_get_contents("http://x.y.z");
} catch (EngineException $e) {
    echo get_class($throwable) . ": CATCHED" . PHP_EOL;
}

Output

PHP Warning:  file_get_contents(): php_network_getaddresses: getaddrinfo for x.y.z failed: Temporary failure in name resolution
PHP Warning:  file_get_contents(http://x.y.z): Failed to open stream: php_network_getaddresses: getaddrinfo for x.y.z failed: Temporary failure in name resolution

It seems that catching doesn't work.
It appears that the line inside the catch block is not executed.

Why?

Because as the first two words of that output show,

PHP Warning:

those are warning messages - not exceptions. Which suggests that you didn't include in your own code the set_error_handler code that blog post demonstrated.
Which, by the way, would throw an ErrorException and not an EngineException. And speaking of, there is no such thing as "EngineException".

PHP 7+ converted some things into exceptions. Not all things.
