I've read multiple examples on how these queries should be written but I'm struggling to get this specific like to run when using bindParam
Would this be the correct way to match usernames that begin with a?
$term = "a";
$term = "'$term%'";
$sql = "SELECT username
FROM `user`
WHERE username LIKE :term
LIMIT 10";
$core = Connect::getInstance();
$stmt = $core->dbh->prepare($sql);
$stmt->bindParam(':term', $term, PDO::PARAM_STR);
$stmt->execute();
$data = $stmt->fetchAll();

The PDOStatement::bindParam() function is an inbuilt function in PHP that is used to bind a parameter to the specified variable name. This function bound the variables, pass their value as input, and receives the output value, if any, of their associated parameter marker.
PDO will work on 12 different database systems, whereas MySQLi will only work with MySQL databases. So, if you have to switch your project to use another database, PDO makes the process easy. You only have to change the connection string and a few queries.
Array Binding: As per our need, we simply need to bind the PHP array to IN() clause and to obtain this functionality, we first need to convert the given array to the form acceptable by the IN() clause, which is a job carried out by PHP implode() function.
bindParam is a PHP inbuilt function used to bind a parameter to the specified variable name in a sql statement for access the database record. bindValue, on the other hand, is again a PHP inbuilt function used to bind the value of parameter to the specified variable name in sql statement.
No, you don't need the inner single quotes so just $term = "$term%";
The statement you're running now would try to match 'a%' instead of a%
bindParam will make sure that all string data is automatically properly quoted when given to the SQL statement.
