This changed as part of https://wiki.php.net/rfc/tostring_exceptions.
It is *not* a fatal error, but an Error exception. You don't need to convert it into an
exception, it already is one.

For a workaround - and potentially the actual "fix", you should catch (Error $e) directly
in your code instead of relying on the error handler.

Description:
------------
In previous releases of PHP, casting instances of stdClass to string would raise an
E_RECOVERABLE_ERROR, but in 7.4, this has changed to raise a E_ERROR fatal error.
I'm not entirely sure this increase of severity is entirely justified as catching fatal errors
in production is still annoying and hard to get meaningful backtraces reported.
Test script:
---------------
<?php
set_error_handler(function($errno, $errstr, $errfile, $errline){
if((error_reporting() & $errno) === 0){
return true;
}
throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
});
try {
(string)new stdClass;
} catch (ErrorException $e){
echo "caught\n";
}
Expected result:
----------------
"caught"
Actual result:
--------------
PHP Fatal error: Uncaught Error: Object of class stdClass could not be converted to string in
/var/webapps/popscan/flupp.php:11
Stack trace:
#0 {main}
thrown in /var/webapps/popscan/flupp.php on line 11
