Description:
------------
Could you please downgrade the error raised by the SoapClient constructor when the 
provided wsdl file cannot be found from E_ERROR to E_WARNING? A network error is 
not fatal.

This issue has been discussed many times but was mixed with other issues (like 
xdebug interference..) and at the end nothing was done. Cf. 
https://bugs.php.net/bug.php?id=47584#1283456233:

> Right, so this is not a PHP bug.  Perhaps a feature request to downgrade that 
> particular error to a Warning instead of a catchable fatal, but that is all I 
see.


Test script:
---------------
$client=@new \SoapClient('garbage',array('exceptions'=>FALSE));
echo 'OK';



Expected result:
----------------
We should see "OK",

Actual result:
--------------
If we use register_shutdown_function to display the contents of error_get_last(), 
we get:

Array
(
    [type] => 1
    [message] => SOAP-ERROR: Parsing WSDL: Couldn't load from 'garbage' : failed 
to load external entity "garbage"
)
