PDO bindParam into one statement?

Question

Is there a way I can put these bindParam statements into one statement?

$q = $dbc -> prepare(\"INSERT INTO accounts (username, email, password) VALUES (:u

helper function is a function that makes you help to avoid writing bunch of repetitive code every time you want to run a query.
This is called "programming" and there is almost none of it on this site, at least under "PHP" tag.
While many peiople thinks that programming stands for copy/pasting chunks of code from manual examples, it's somewhat different. Although it's hard to learn but really worth it, especially if you're devoting yourself to web-developing.

As you can see, no accepted answer did no real help for you, as you still have to write something like

$sth->execute(array(':username' => $_POST['username'], 
                    ':email' => $_POST['email']
                    ':password' => $_POST['password']);

as many times as many fields in your table, which makes not much difference from your initial approach, still makes you write each field name FOUR times.

But being a programmer, you can use powers of programming. A loop, for example - one of cornerstone programming operators.
Every time you see repetitions, you know there should be a loop.

for example, you can set up a list of fields, naming them only once. And let a program do the rest.

Say, such a function like this one

function pdoSet($fields, &$values, $source = array()) {
  $set = '';
  $values = array();
  if (!$source) $source = &$_POST;
  foreach ($fields as $field) {
    if (isset($source[$field])) {
      $set.="`$field`=:$field, ";
      $values[$field] = $source[$field];
    }
  }
  return substr($set, 0, -2); 
}

being given an array of field names, it can produce both insert statement and data array for you. Programmatically. So, your code become no more than these 3 short lines:

$fields = array('username', 'email', 'password');
$stmt = $dbh->prepare("INSERT INTO accounts SET ".pdoSet($fields,$values));
$stmt->execute($values);
