PHP严格搜索

Question

我遇到了搜索问题，我正在开发一个项目，以便用户可以根据zipcodes查找交付日期。荷兰和比利时都有拉链码，荷兰的拉链码只是数字（例如1000），而比利时的拉链码在它前面有一个B（例如B1000）。当我搜索1000时，它显示1000（荷兰邮政编码）和B1000（比利时邮政编码）。我尝试使用'='，'MATCH'，'=='，'STRICT'和'==='而不是'LIKE'。我希望你们能帮我解决这个问题。提前致谢。

搜索，没有严格的匹配

编辑：我通过删除前面和搜索后的％来解决严格匹配的问题。

Answer 1

关于严格匹配的问题：

通过删除搜索前后的％来修复它：

if ($search) {
            $nlbelevering = $em->createQuery('Select a FROM AppBundle:Nlbelevering a WHERE a.postcode LIKE :query')
                    ->setParameter('query', $search);
        } else{
            $nlbelevering = $em->createQuery('Select a FROM AppBundle:Nlbelevering a WHERE a.postcode LIKE :query')
                    ->setParameter('query', $search);
        }
