尝试以下代码（已修复）：
// Create an array of the values to use in the list$villes = array("paris", "fes", "rabat");// Generate the SQL statement.// The number of %s items is based on the length of the $villes array$sql = " SELECt DISTINCT telecopie FROM `comptage_fax` WHERe `ville` IN(".implode(', ', array_fill(0, count($villes), '%s')).")";// Call $wpdb->prepare passing the values of the array as separate arguments$query = call_user_func_array(array($wpdb, 'prepare'), array_merge(array($sql), $villes));echo $query;implode()
array_fill()
call_user_func_array()
array_merge()
