Very Confusing PDO php exec() connection issue -


i have run confusing issue connecting database via php pdo using exec().

i have thrown following snippet illustrate point.

$host = "localhost"; $db_name = "some_db"; $user_name = "some_user"; $pass_word = "some_password";  try { // assign pdo object db variable $dbh = new pdo("mysql:host=$host;dbname=$db_name;charset=utf8", $user_name, $pass_word, array(pdo::mysql_attr_init_command => "set names 'utf8'")); $dbh->setattribute( pdo::attr_errmode, pdo::errmode_exception ); echo "yahoo connected"; } catch (pdoexception $e) { //output error - log error file rather output user. echo "connection error: " . $e->getmessage(); }

when run code via browser connects fine when run @ command line gives following error:

connection error: sqlstate[28000] [1045] access denied user 'some_user'@'localhost' (using password: no)

needless confusing password indeed set can see in code above , connection works , prints yahoo screen in browser. ideas appreciated.

your snippet wrong. ought without useless try-catch block:

$host = "localhost"; $db_name = "some_db"; $user_name = "some_user"; $pass_word = "some_password";   $dsn = "mysql:host=$host;dbname=$db_name;charset=utf8" $opt = array(     pdo::attr_errmode            => pdo::errmode_exception,     pdo::mysql_attr_init_command => "set names utf8",     // other options  ); $dbh = new pdo($dsn, $user_name, $pass_word, $opt); echo "yahoo connected";

this way complete error message,including stack trace show actual file runs - in there empty password used.

it important have error_reporting(e_all); tell possible issues variables scope
