PDO bindParam not working in foreach

Question

I am using PDO for an application but getting a problem for PDO bindParam(). I have an array and I want to use the values of array for PDO bi

Answer 1

use bindValue() instead of bindParam(). bindParam() binds to a reference, so when you execute the query all the parameters use the last value of $val.

Answer 2

If you already have the items in an array, there's no reason to call $stmt->bindParam in a loop; just do:

$con = $this->connection();
$stmt = $con->prepare($sql);
$stmt->execute($params);
$result = $stmt->fetchAll();

Per the PHP documentation:

Execute the prepared statement. If the prepared statement included parameter markers, you must either:

call PDOStatement::bindParam() to bind PHP variables to the parameter markers: bound variables pass their value as input and receive the output value, if any, of their associated parameter markers

or pass an array of input-only parameter values
