c# - Regex Counting Characters in a text field -


i trying count characters in text field. found how count characters.

string st = textbox1.text; this.textbox2.text = regex.matches(st, ".|").count.tostring();

but need create 2 more separate counts, caps, numbers, - or # (not including) @

eg. la-fg4-detf-djjjthd-s@t-jhf-f1-f2 count 21

and other 1 need count @ (including) , caps, numbers, - or # end of text field.

eg. la-fg4-detf-djjjthd-s@t-jhf-f1-f2 count 12

 string input = "la-fg4-detf-djjjthd-s@t-jhf-f1-f2"; int atindex = input.indexof('@'); int count1 = regex.matches(input.substring(0, atindex), "[0-9a-z#-]").count; int count2 = regex.matches(input.substring(atindex, input.length - atindex), "[0-9a-z#@-]").count;

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
