php - Login script using PDO extension not working -


i unsure if doing started working pdo , not able code work. continue error "sorry not connect" , unable figure out wrong.

included below code using:

function dorun( $data ) { try { $db = new pdo('mysql:host=localhost;dbname=testdata', 'root', 'root'); $db->setattribute(pdo::attr_errmode, pdo::errmode_exception); $stmt = $db->prepare(' select username, pass testtable username = :name , pass = :pass '); $stmt->bindparam(':name', $username, pdo::param_str); $stmt->bindparam(':pass', $pass, pdo::param_str); $stmt->execute(); //$result = $stmt->fetchall(pdo::fetch_assoc); $result = $stmt->fetchcolumn(); if($result == false) { echo 'sorry not connect'; } else { $_session['username'] = $user; echo 'logged in as' . $user; } } catch (pdoexception $e) { echo "throw"; } $db = null; }

this give 0 rows seems $username , $pass not defined:

 $stmt->bindparam(':name', $username, pdo::param_str); $stmt->bindparam(':pass', $pass, pdo::param_str); ^^^^^^^^^

you want elements $data variable feeding function username , password.

later on using variable $user undefined well.

what $data contain?

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
