Description:
------------
mistake in PHP example: en/reference/ifx/functions/ifx-query.xml

file: en/reference/ifx/functions/ifx-query.xml
...
$res_id = ifx_query("select * from orders", $conn_id);
if (! $res_id) {
    printf("Can't select orders : %s\n<br />%s<br />\n", ifx_error());
    ifx_errormsg();
    die;

// printf(): Too few arguments
// unexpected ');' after 'ifx_error()'

Expected result:
----------------
$res_id = ifx_query("select * from orders", $conn_id);
if (! $res_id) {
    printf("Can't select orders : %s\n<br />%s<br />\n", ifx_error(), ifx_errormsg());
    die;
