PDO Database access WHERE title = $title

Question

I\'m trying to learn to use PDO instead of MySQLi for database access and I\'m having trouble selecting data from the database. I want to use:

$STH = $DBH->qu

It's likely a SQL syntax error, because you forgot to quote $title. It ended up as bareword in the query (also not even interpolated as string), resulting in an error. And your PDO connection was not configured to report errors. Use ->quote() on arguments before the ->query():

$title = $DBH->quote($title);
$STH = $DBH->query("SELECT * FROM ratings WHERE title=$title ");

Or better yet, use parameterized SQL:

$STH = $DBH->prepare("SELECT * FROM ratings WHERE title=? ");
$STH->execute(array($title));
