mysql - mysqli DB connect scope? -

-

i'm trying use prepared statements insert data database, within function.

the following works great when called outside file:

function insert($value1, $value2) { $mysqli = new mysqli("localhost", "***", "***", "***");     if (mysqli_connect_errno()) {     printf("connect failed: %s\n", mysqli_connect_error());     exit(); }     if ($stmt = $mysqli->prepare("insert table (col1, col2) values (?, ?)")) {     $stmt->bind_param('ss', $value1, $value2);     $stmt->execute(); } }

however want move connect string outside of function, results in scope issues. i've read need class this, can explain example please?

thanks

the easiest thing move connect line outside function (into global scope) , put following inside function @ start:

global $mysqli;

see: http://php.net/global

you can use class if , have class variable store connection more involved. again, explained in php documentation examples of creating class, methods & variables , using it.

http://php.net/class

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...
