php - PDOException “could not find driver” -

-

i have installed debian lenny apache, mysql, , php , receiving pdoexception could not find driver.

this specific line of code referring to:

$dbh = new pdo('mysql:host=' . db_host . ';dbname=' . db_name, db_user, db_pass)

db_host, db_name, db_user, , db_pass constants have defined. works fine on production server (and on previous ubuntu server setup).

is php installation?

searching internet has not helped, experts-exchange , examples, no solutions.

you need have module called pdo_mysql. looking following in phpinfo(),

pdo_mysql  pdo driver mysql, client library version => 5.1.44
