true :-)
<?php
$names = array( "joe", "bob" );
$placeholders = implode( ",", array_map( function($x){return "?"}, $names ) );
$sql = "select 'bob' IN ($placeholders)";
$stmt = $dbh->prepare($sql);
$stmt->execute($names);
?>
PHP from several years cries for postgres array support in PDO. And
personally I would rather discourage programmers from constructing
delimited array string in code - more complicated than first option,
needs careful character escaping, etc.
select array['a',null,'','tab is ','quote is "','comma is ,'];
array
-------------------------------------------------------
{a,NULL,"","tab is ","quote is \"","comma is ,"}
