在PHP中处理Solr结果的理想方法？

首先，我知道有一些类似的问题与此类似，但我认为这种情况不同，足以证明它自己的问题

我正在运行Solr索引，通过安装在LAMP服务器上的jetty。我目前使用

simplexml\u load\u file

函数引入搜索结果，然后通过几个函数解析它们。我对这个过程很满意，直到我开始遇到一个根本性的问题

字段名不会通过simplexml函数传递。比如这个结果,

<doc>
  <float name="score">0.73325396</float>
  <str name="add1">Ravensbridge Drive</str>
  <str name="comments">0</str>
  <str name="company">Stratstone Lotus Leicester</str>
  <str name="feed_id"/>
  <str name="id">1711765</str>
  <str name="pcode">LE4 0BX</str>
  <str name="psearch">LE4</str>
  <str name="rating">0</str>
</doc>

当找到一个完整的数据集时，数组中存储了11位数据，但当其中一些数据丢失时，数据就会四处移动，我的解析器就会崩溃

所以，我已经研究了库/类来正确地完成它。即两个主要的,；但两者似乎都过于复杂，几乎没有实际的例子，而且它们都不支持不同的solr内核，我使用了几种

最好用什么？我现在被困在这里，任何帮助都将不胜感激

谢谢

当然可以使用现有的客户端之一。至于多核支持，只需为Solr的每个实例创建一个客户端实例即可

Solr扩展功能强大得多，但使用起来仍然非常直观。这里有两个示例代码段，它们使用两个库进行基本查询并返回结果：

感谢回复nuqqsa！我认为选项数组中的路径var将是核心路径，对吗？solr文件目前在我的根目录之外，所以我想我必须把它们移到根目录里面？我还有一些问题，但我会先尝试了解一下文档，再次感谢！这些示例在

http://localhost:8080/solr

，其中/solr（path）是相对于域的路径。这必须适应Solr API实例所在的位置。文件在根目录之外是什么意思？是的，这是一个很好的起点！：）solr php客户端使用JSON而不是XML解析响应。这在大多数情况下都很好，但当Solr的JSON响应编写器做了它不应该做的事情（比如在同一级别上设置同名键）时，就会中断。例如，在使用多个排序规则时会发生这种情况。
