mysql - PHP If / else user exists on database set variable to 0 or 1 -


i have code check if user exists in database. want assign $account 1 if exits, , 0 if doesn't. thought code work setting $account 0 think im missing trick. appreciated.

$con = mysql_connect(db_host, db_user, db_pass) or die("couldn't make connection."); if (!$con) { die('could not connect: ' . mysql_error()); } mysql_select_db(db_name, $con); $sql="select user_name users"; $result = mysql_query($sql) or die(mysql_error()); $row = mysql_fetch_assoc($result); if ($row['user_name'] == '$user_name'){ $account = 1; }else{ $account = 0;}

thanks

you can't put variables in string if use single quotes ' (plus it's not necessary!). below rectifies issue, , shortens if/else statement one-liner.

$account = $row['user_name']==$user_name ? 1 : 0;

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
