PHP数组搜索不工作
有谁能帮我解释一下为什么我的array_搜索在我写的这个PHP脚本中不起作用。我已经处理这件事好几天了，无法解决这个问题。我试着将数组搜索移动到所有地方，在循环内，在循环外，我得到了相同的结果。我尝试过搜索不同的数组值，我尝试过包含我自己的函数来搜索我在网上找到的数组。我知道这些值在数组中，因为我已将数组打印到.txt文件中进行调试，现在我不知道下一步要查找什么。有什么想法吗PHP数组搜索不工作,php,arrays,search,Php,Arrays,Search,有谁能帮我解释一下为什么我的array_搜索在我写的这个PHP脚本中不起作用。我已经处理这件事好几天了，无法解决这个问题。我试着将数组搜索移动到所有地方，在循环内，在循环外，我得到了相同的结果。我尝试过搜索不同的数组值，我尝试过包含我自己的函数来搜索我在网上找到的数组。我知道这些值在数组中，因为我已将数组打印到.txt文件中进行调试，现在我不知道下一步要查找什么。有什么想法吗 <?php //this variable tells us how many drupal nodes

我认为你已经改变了你的论点
$ArrSearch = array_search("EMPLOYEE NO. ", $currArray);
@米加：我不确定这是否是问题所在，或者他们是否已经筋疲力尽，在经历了两天的挫折之后，他们只是在尝试任何事情。我想你已经改变了争论的方向
$ArrSearch = array_search("EMPLOYEE NO. ", $currArray);
您需要在代码中交换针线和干草堆我猜您正在搜索包含员工编号的行，例如“员工编号7”等等。如果您使用
array\u search（“EMPLOYEE NO.”，$currray）如果要搜索以“EMPLOYEE NO.”开头的值，则必须在数组中循环并使用
strpos（）array\u search（“EMPLOYEE NO.”，$currray）如果要搜索以“员工编号”开头的值，则必须在数组中循环并使用
strpos（）
