  BEGIN
      p2 := p1 * 2;
  END;

*/

$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}

$p1 = 8;

// When parsing PL/SQL programs, there should be a final semi-colon in the string
$stid = oci_parse($conn, 'begin myproc(:p1, :p2); end;');
oci_bind_by_name($stid, ':p1', $p1);
oci_bind_by_name($stid, ':p2', $p2, 40);

oci_execute($stid);

print "$p2\n";   // prints 16

oci_close($conn);

Notes

Note:

This function does not validate sql_text. The only way to find out if sql_text is a valid SQL or PL/SQL statement is to execute it.
