PHP严格搜索
我在搜索方面遇到了问题，我正在做一个项目，这样用户就可以根据zipcodes找到交付日期。荷兰和比利时都有Zipcode，荷兰Zipcode只是数字（例如1000），比利时Zipcode前面有一个B（例如B1000）。当我搜索1000时，它同时显示1000（荷兰zipcode）和B1000（比利时zipcode）。我试着用“=”、“匹配”、“严格”和“=”，而不是“喜欢”。我希望你们能帮我解决这个问题。提前谢谢 控制器PHP严格搜索,php,symfony,matching,strict,Php,Symfony,Matching,Strict,我在搜索方面遇到了问题，我正在做一个项目，这样用户就可以根据zipcodes找到交付日期。荷兰和比利时都有Zipcode，荷兰Zipcode只是数字（例如1000），比利时Zipcode前面有一个B（例如B1000）。当我搜索1000时，它同时显示1000（荷兰zipcode）和B1000（比利时zipcode）。我试着用“=”、“匹配”、“严格”和“=”，而不是“喜欢”。我希望你们能帮我解决这个问题。提前谢谢 控制器 <?php namespace AppBundle\Controll

编辑：我通过删除搜索前后的%解决了严格匹配问题。关于严格匹配的问题： 通过在搜索中删除前面和后面的%：
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);
}
为什么不搜索：您的_字段=pincode，而不是像%pincode%这样的_字段？@Shan，因为它不会显示任何记录，但我通过删除%.解决了这个问题，正如@Shan建议的那样？请你们其中一位写下来作为答案，然后接受它。@Veve我已经用答案编辑了这篇文章，但我还有另一个问题。这不是解决问题的方法。编辑您的代码以反映您的修改，然后改写您的问题。
