Fatal error: Call to undefined function: quote()

[Todd Mortensen]

I have just setup Kronolith to use sql as its driver but get this error.
Anyone seen it before?

Fatal error: Call to undefined function: quote() in
/web/htdocs/test.domain.com/horde/kronolith/lib/Driver/sql.php on line 112

Here is my conf.php

$conf['calendar']['driver'] = 'sql';
$conf['calendar']['params'] = array(
     'phptype'       => 'mysql',
     'hostspec'      => 'localhost',
     'protocol'      => 'unix',
     'username'      => 'hordeuser',
     'password'      => 'XXXXXXX',
     'database'      => 'hordecvs',
     'port'          => '3306',
     'table'         => 'kronolith_events'
);
