Usage

global $wpdb;
$wpdb->replace( $table, $data, $format );
$table(string) (required)
Table name.
$data(array) (required)
Data to insert (in column => value pairs). Both $data columns and $data values should be "raw" (neither should be SQL escaped). Sending a null value will cause the column to be set to NULL - the corresponding format is ignored in this case.
$format(array/string)
An array of formats to be mapped to each of the value in $data. If string, that format will be used for all of the values in $data. A format is one of '%d', '%f', '%s' (integer, float, string). If omitted, all values in $data will be treated as strings unless otherwise specified in wpdb::$field_types.
Default: null
