你能添加示例代码吗？当然可以。你说的是解析的html表格；您是否正在尝试解析这些统计数据的HTML表（例如，使用SimpleXML或DOMDocument），使用PHP执行某些操作，然后再次打印出来？或者您正在从PHP生成HTML表？目前使用simple_HTML_dom。请向我们展示您的尝试、预期结果和当前得到的结果。谢谢。有两件事：1]列0应按定义的顺序排序：PG=1 | SG=2 | SF=3 | PF=4 | C=5。现在这并不意味着位置的改变，比如哈登从PG换到C，这应该会让他落后于施罗德。但第4列的部分工作正常。2] 在我的基本代码中放在哪里？当然，你能给我一个更大的数据样本吗。编辑了这个问题。正如你在表格末尾看到的，有一些球员应该被归类到同一位置的其他球员。所有位置相同的球员都应该按第4列排序。@Chris我更新了我的答案。看看这是否有帮助。。我对pos的排序顺序仍有点粗略。此更新确实保留了您发布的关系。@Chris我在代码中犯了一个错误。我已经用新的编辑更新了代码。。我切换了条带标签和修剪功能的顺序。我也发布了新的结果。让我知道。
