php - remove "resourse id #--" from image name -

-

when displaying(php echo) image name server,it's shows like,

resource id #32global_2012062513406170744fe83172d6c99.jpg resource id #33330394727_2012062613406707734fe90335d0a5e.jpg

how can remove "resource id #32" associated image name? can display image server? or there other way display images? code is

 69 if(is_dir($dir))  70         {                 71         $dir = opendir($dir);     72                 while (false !== ($file = readdir($dir)))  73                 {         74                         if ($file != "." && $file != "..")  75                         {  76                                 $files[] = $file;  77                         }  78                 }  79         closedir($dir);  80         }  81 //srand ((double) microtime( )*1000000);  82 $randnum = mt_rand(0,(sizeof($files)-1));  83 $img = $dir.$files[$randnum];  84 echo $img;

thanks!

if(is_dir($dir)) {                    $opendir = opendir($dir);        while (false !== ($file = readdir($opendir)))     {                if ($file != "." && $file != "..")         {             $files[] = $file;         }     }     closedir($opendir); } //srand ((double) microtime( )*1000000); $randnum = mt_rand(0,(sizeof($files)-1)); $img = $dir.$files[$randnum]; echo $img;

use this.

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...
