php - What is the best generic class or package to use for input validation? -

-

what best, secured , user-friendly easy use validator class or plugin can use in php coding validate common user inputs e-mail addresses, urls, integers, etc.?

e.g. http://code.google.com/p/owasp-esapi-php/. there better way?

or using filter_input best way? e.g.

$value = filter_input(input_get, "value", filter_validate_int,         array("options" => array("min_range" => 15, "max_range" => 20)));

or custom coding? e.g.

if (isset($_get["value"])) {     $value = $_get["value"]; } else {     $value = false; } if (is_numeric($value) && ($value >= 15 && $value <= 20)) {     // run code } else {     // handle issue }

any expert views on this? prefer lazy style, like:

filer_input($post);

is there that?

if you're not familiar such libraries may not user- (developer-) friendly, think should @ symfony2 validator component. installed throught composer, can used standalone , has excellent documentation here: http://symfony.com/doc/current/book/validation.html , github repository can found here: https://github.com/symfony/validator .

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
