Validating a url

Michael's regex considers [email protected] a valid address * which conflicts with section 2.3.5 of RFC 5321 which states that: * * Only resolvable, fully-qualified domain names (FQDNs) are permitted * when domain names are used in SMTP.In other words, names that can * be resolved to MX RRs or address (i.e., A or AAAA) RRs (as discussed * in Section 5) are permitted, as are CNAME RRs whose targets can be * resolved, in turn, to MX or address RRs.In addition to AMP validity, you may also want to confirm that your AMP document is discoverable to third-party platforms.

In which case filter_var returns a 0, aka false when used as a boolean.I think "Beware a valid URL need not specify..." would be better.Often I see some code like the following:$value = "12";if( filter_var($value, FILTER_VALIDATE_INT) )The above works as intended, except when $value is "0". For the correct behavior, you have not only to check if it is equal (==) to false, but also identic (===) to FALSE:$value = " 0 ";if( filter_var($value, FILTER_VALIDATE_INT) === FALSE )I hope, I could help.If FILTER_NULL_ON_FAILURE is not used then NULL is returned when the variable name is not set in the external variable array, TRUE is returned for "1", "true", "on" and "yes" and FALSE is returned for everything else.Contrary to what documentation implies, the FILTER_NULL_ON_FAILURE seem to affect any validation filter, not just FILTER_VALIDATE_BOOLEAN.

FILTER_VALIDATE_URL does not work with URNs, examples of valid URIs according to RFC3986 and if they are accepted by FILTER_VALIDATE_URL: [PASS] ftp://example.org/rfc/rfc1808[PASS] gopher://spinaltap.example.edu/00/Weather/California/Los Angeles [PASS] mailto:[email protected][PASS] news:comp.[PASS] telnet://example.edu/ [PASS] ldap://[2001:db8::7]/c=GB? In 2007 someone suggested it's not acceptable (see https://net/bug.php?
