I know,blabla'@email.com type is correct for universal types but is it usefull ? 

did you mean "i can use like that email" ? :)
 [2017-04-18 22:37 UTC] spam2 at rhsoft dot net 
"but is it usefull" is not the qestion when it comes to validation

enough fools out there decided that the + sign is not useful and hence not accepted in webforms while it's perfect legal and on a proper mailserver would put mails in the subfolder "test" in case of "test+xxx@xecmplaec.com"

> did you mean "i can use like that email" ? :)

yes, if not some random fool decides that he don't care about RFC's and reject it

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

This is expected behavior.

we are talking about validate and i think validate filters should be reallistic.

If i have a software developed with php,i don't want accept like as "bla'@com" from web forms. I think a lot of webmasters don't want like  "blabla'@com" emails in their databases and need another functions for filter. If FILTER_VALIDATE_EMAIL had a flag for strong filter,it was be most useful

I am sorry for this situation,I thought this was a mistake

god damned NO they should be CORRECT - no i am not a php upstream develper but just shocked about that much ignorance which explains so many weird behavior of software

we have enough broken software and you demand another one....
