declaring session variables php -


is not mandatory use session_start() before using session variables in php? tried following piece of code without declaring session_start() @ beginning, worked fine.

so, i'm confused. please !!!!

also, did not use $_post or $_get pass $uname home.php, still how work? if use include 'home.php' treat login.php , home.php same page?

// code login.php// <? require_once 'db_connect.php'; if (isset($_session ['user_id']) && !empty($_session ['user_id'])) { $u_name = $_session['user_name']; include 'home.php'; } else { //some stmt } ?> /*******home.php file ****/ <?php require_once 'dbconnect.php'; $_session['username'] = $u_name; //echo $_session['username']; //blah blah ?>

you need it, if session.autostart not set in php.ini. know then.

do not call in db_connect.php? also, i'm pretty sure wouldn't errors, session empty.

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
