zend framework - Does PHP's built-in filter_input work correctly? -

-

i tried php's built-in function: filter_input()

var_dump(filter_var('john.doe.@gmail.com', filter_validate_email));

output:

string(19) "john.doe.@gmail.com"

then tried latest release of zend framework (1.11.3):

$validator = new zend_validate_emailaddress();   if ($validator->isvalid('john.doe.@gmail.com')) {     echo 'ok'; } else {     foreach ($validator->getmessages() $message) {             echo "$message\n";     } }

output:

'john.doe.' can not matched against dot-atom format
'john.doe.' can not matched against quoted-string format
'john.doe.' no valid local part email address 'john.doe.@gmail.com'

either built-in function should return false or zend method 'ok'.

my hubmle question is:
which 1 right?

http://framework.zend.com/manual/en/zend.validate.set.html doesn't indicate wether they're being rfc-strict or not, lets @ source.

in source, _validatelocalpart() defines ebnf they're matching against:

    // dot-atom characters are: 1*atext *("." 1*atext)     // atext: alpha / digit / , "!", "#", "$", "%", "&", "'", "*",     //        "+", "-", "/", "=", "?", "^", "_", "`", "{", "|", "}", "~"     if (preg_match('/^[' . $atext . ']+(\x2e+[' . $atext . ']+)*$/', $this->_localpart)) {

it looks stay strict - local part cannot begin or end dot.

the pattern above same in rfc2822 spec: http://www.ietf.org/rfc/rfc2822.txt - , isvalid docblock in zend/validate/emailaddress.php references using 2822.

so, if want rfc2822 compliant, zend_validate_emailaddress doing right, , likely, filter_input doing out of spec.

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
