php - Why does filter_var($email, FILTER_VALIDATE_EMAIL) allow test@test? -


I was just setting up the verification for the form in which I used the filter_var function to check my verification Attempted email address I do not know if filter_var actually allows anywhere (because the documentation is very simple), and I found out that it is allowing an email address like test @ test. Do not have to have a .com, .net etc ... in the domain?

See behavior has changed somewhere around April and.

This e-mail is actually invalid, or at least this is what the PHP developers think is the source: 

  / * * Below are regex Michael Based on a regex by Rushton * However, this is not the same, I've considered it only by treating the path * addresses as valid. Michael's Reggae considers an @B as a valid address * that fights with section 2.3.5 of RFC 5321, which states that: * * Only the claimant, the full-qualified domain name (FQDN) is allowed * when In other words, names that are * MX RR or address (i.e. AAAAA) RR (as discussed in section 5) can be solved, such as CNA RR, whose domain names are used in SMTP. Goal * Resolve In return, MX or address RRS local alias or * ineligible names should not be used.

This bug fixes for PHP 5.3.3 and PHP 5.2.14.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
