Please note that in my earlier note about having oci_bind_by_name() in a function, this becomes a little more complicated when returning values like "UPDATE table SET bla='blubb' RETURNING id INTO :id". 

You can do it as follows:

<?php
function sql($q, &$vars_in=array(), &$vars_out=array()) {
  ...
  $stid = oci_parse($conn, $q);
  ...
  reset($vars_in);
  do {
    if (current($vars_in)===FALSE) {
      break;
    }
    $b = oci_bind_by_name($stid, key($vars_in), current($vars_in));
    // insert exception handling here
  } while (each($vars_in) !== FALSE);

  // VARS TO RETURN
  // we'll fix this to integer type because for now we need this for index IDs
  foreach ($vars_out as $k => $v) {
    $b = oci_bind_by_name($stid, $k, $vars_out[$k], -1, SQLT_INT);
    // insert exception handling here
  }

  ...
}
?>

Use like this:

<?php
$blubb = 'blubb';
$b = array(':bla' => $blubb);
$b_out = array(':id' => ''); // leave value empty
$x = sql($q, $b, $b_out);
$id = $b_out[':id'];
?>

(The point is: you would not be able to return anything into $b[':bla'] because $b[':bla'] becomes current($vars_in) inside sql() and cannot be written to.)
