Question

我发现我不认为我想搜索数组键并打印它们的值，我希望搜索一部分填写的条目，即，如果我搜索了“haw＆＃39;它将在第一列中返回Hawthorn，Hawt等每一行。

这就是我目前用于搜索的内容，如果我为这些值提供全名，它可以正常工作（虽然我意识到它可能很丑陋且效率低下）。但是，我希望能够搜索“geoff＆＃39;找到所有的geoffrey，然后显示他们行的相关部分。

我已经尝试了各种方法将字符串转换为数组，将数组转换为字符串，这是基于我从我试过的各种函数中得到的错误，但我无法解决它。它在搜索中是如此常见的功能我真的认为我错过了一些重要的东西。我很新，我需要帮助！

最近我尝试使用＆＃39; In_array＆＃39;但这也没有帮助。谢谢，如果有人可以排序它！

Answer 1

在脚本开头的某处定义搜索/比较功能

function searchString($haystack, $needle) {
    return strpos($haystack, $needle) === 0 ? true : false;
}

并在IF语句f.e。

中使用它

if(searchString($show[0], $upretailer) && searchString($show[2], $upsitename)) {
    ...
}

<?php

$sitename = $_GET['sitename'];
$upsitename = strtolower($sitename);

$area = $_GET['area'];
$uparea = strtolower($area);

$postcode = $_GET['postcode'];
$uppostcode = strtolower($postcode);

$file = fopen("houselist.csv","r");
ini_set('auto_detect_line_endings',TRUE);

$i=0;

while ( ! feof ( $file ) ) {
$show = fgetcsv($file);

  $track="nope";

  foreach ($show as $val) {

   if (strpos($val,$upsitename) !== false)
   {
    $track="true";
    echo $upsitename . " appeared in " . $val . " on line " . $i . "</br>";
   }
   if (strpos($val,$uppostcode) !== false)
   {
    $track="true";
    echo $uppostcode . " appeared in " . $val . " on line " . $i . "</br>";
   }
   if (strpos($val,$uparea) !== false) 
   {
    $track="true";
    echo $uparea . " appeared in " . $val . " on line " . $i . "</br>";
   }

  }

  if($track=="true")
  {
  echo 
  "</br></br><table class='output'>
  <tr>
  <td>$show[0] </td>
  <td>$show[1]</td>
  <td>$show[2]</td>
  <td>$show[5]</td>
  <td>$show[6]</td>
  <td>$show[8]</td>
  </tr>
  </table>";
  }

$i++;      
}

fclose($file);
?>

使用PHP，如何在数组中搜索部分字符串，然后显示数组的多个部分？
