Question

我从文本文件结构中读取如下： AAA BBB CCC 并在数组中写入，现在我需要使用此名称进行查询，选择所有具有此名称的colounms并将结果写入csv文件，文件读取工作正常但查询只返回1行，只返回ccc最后一个数组。帮助我。

这是我的代码：

<?php
    $servername = "localhost";
    $username = "root";
    $password = "";
    $db = "tirocinioriginale";

    $con = mysqli_connect($servername, $username, $password,$db);


    if (!$con) {
        die("Connessione fallita: " . mysqli_connect_error());
    }
    $myfile = fopen("aziende1.txt", "r") or die("Unable to open file!");
    //echo fread($myfile,filesize("aziende1.txt"));

    $aziende = array();

    while (!feof($myfile)) {
       $aziende[] = fgets($myfile);
    }
    fclose($myfile);


   echo implode(',',$aziende);
    $query = "SELECT * FROM azienda  WHERE nome IN ('".implode("','",$aziende)."')";
    $result = $con->query($query);
    $azienderow = array();
    while($row = $result->fetch_assoc())
    {
      array_push($azienderow, $row);
    }
      echo "Connessione successo";

   var_dump($azienderow);


    //$row = mysql_fetch_assoc($result);

  /*  $fp = fopen('dumpaziende.csv', 'w');

    foreach ($row as $val) {
      fputcsv($fp, explode($val));
    }

fclose($fp);
*/
  //var_dump($aziende);
mysqli_close($con);
?>

如果使用我的代码，结果是：文件： aitech ItalData

aitech，ItaldataConnessione successoarray（1）{[0] =＆gt; array（12）{[“id_azienda”] =＆gt; string（3）“244”[“nome”] =＆gt; string（8）“ItalData”[“settore”] =＆gt; string（17）“Sviluppo software”[“website”] =＆gt; string（5）“sadsa”[“email”] =＆gt; string（11）“dasdasddsad”[“curriculum_aziendale”] =＆gt; string（9）“dasdasdas”[“tematiche”] =＆gt; string（7）“fafdaew”[“n_borse”] =＆gt; NULL [“data_stipula_convenzione”] =＆gt; string（10）“2018-03-14”[“data_fine_convenzione”] =＆gt; string（10）“2018-03-20”[“attiva”] =＆gt; string（1）“1”[“tipologia_id”] =＆gt; string（1）“3”}}

Answer 1

echo implode(',',$aziende);

产地：

aitech ,Italdata
//    ^-- see this space? this is probably the problem

查询将呈现如下：

$query = "SELECT * FROM azienda  WHERE nome IN ('aitech ','Italdata')";
//     the trailing space will impact matching --------^

您可以使用：

implode("','",array_map('trim',$aziende))

或trim()在while循环中进行修剪，然后再存储数据。
