The data structure is the "Structure and Identification of Management Information for TCP/IP-based Internets" (SMI) [RFC1155], and the "Management Information Base for Network Management of TCP/IP-based Internets" (MIB-II) [RFC1213].The SMI includes the provision for parameters or codes to indicate experimental or private data structures. The older "Simple Gateway Monitoring Protocol" (SGMP) [RFC1028] also defined a data structure.If the application protocol is not listed in the registry, an OID value of the form or are used for TCP-based and UDP-based protocols, respectively.In either case 'port' corresponds to the primary port number being used by the protocol." ::= This registry is not in use.It says FQDNs are permitted, and com, org, or va are (well, may be) valids FQDNs. Some TDLs (although few of them) have MX RRs, the for example "[email protected]" is correct.The description for FILTER_VALIDATE_URL seems incorrect/misleading. "Beware a valid URL may not specify the HTTP protocol" implies a valid URL cannot specify the HTTP protocol.Returns: PHP Version: 5.2.14 //On MY server, may be different depending on which version you have installed.
For example, -- assuming no other OID is assigned for SMTP, an OID of -- could be used, since SMTP is a TCP-based -- protocol that uses port 25 as its primary port.
For the management of hosts and gateways on the Internet a data structure for the information has been defined.
This data structure should be used with any of several possible management protocols, such as the "Simple Network Management Protocol" (SNMP) [RFC1157], or the "Common Management Information Protocol over TCP" (CMOT) [RFC1095].
A word to the wise regarding floats.$t = '312041.25 € instead of 896.70 €';echo filter_var ($t, FILTER_SANITIZE_NUMBER_FLOAT, FILTER_FLAG_ALLOW_FRACTION);will return312041.25896.70which is likely not what you were expecting.
In 2007 someone suggested it's not acceptable (see https://net/bug.php?
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 the domain part, a comment in the source code (in ext/filter/logical_filters.c) justifies this rejection thus: * The regex below is based on a regex by Michael Rushton. I changed it to only consider routeable * addresses as valid.
