            本文实例讲述了PHP实现的通过参数生成MYSQL语句类。分享给大家供大家参考，具体如下：
这个类可以通过指定的表和字段参数创建SELECT ,INSERT , UPDATE 和 DELETE 语句。
这个类可以创建SQL语句的WHERE条件，像LIKE的查询语句，使用LEFT JOIN和ORDER 语句
clear_all_assign(); // to refresh all property but it no need when first time execute
$object -> setFields( $fields );
$object -> setValues( $values );
$object -> setTables( $tables );

" ;
