Question

I’ve been having an issue executing prepared queries using bindParam() with PDO in a loop. Basically what I’m trying to do is loop through an array, and with each array element, return the data from the database. Now I realise that ->bindParam() is supposed to bind the variable to the query, but how does this work with arrays? Because I can’t seem to get it working :S

Here’s my code so far:

<?php
    $i = 0;
    $statement = $conn->prepare("SELECT * FROM users WHERE id = :id");
    $statement->bindParam(":id", $friendListIDs[$i], PDO::PARAM_STR);
    $friendListIDs = explode($details['friends'], " ");
    while($i <= count($friendListIDs))
    {
          $statement->execute();
          $row = $statement->fetch();
          echo "<img src='../img/friend_icon.png' alt='' align='left' />
                <span>
                <a href='#'>".$row['firstname']." ".$row['surname']."</a>
                <br />
                <a href='#'>100% wishes fulfilled</a>
                </span><br /><br />";
                $i++;
    }   
?>

Rather than use bindParam you can add an array parameter to $statement->execute like so:

$statement->execute(array(":id"=>$friendListIDs[$i]));
