Question

使用drupal管理我的内容。我想搜索我的所有内容标题和正文，并找出每个单词在整个内容中重复的次数。

可能是通过sql查询，但我没有使用sql的经验。

有什么想法吗？

Answer 1

此代码搜索特定字符串的 ANY 内容类型的正文字段和所有字段。您可以通过命令行运行它。假设您将其保存为＆＃34; fieldsearch.php＆＃34;，然后您可以将其运行为：

php fieldsearch.php＆＃34; myStringForWhichToSearch＆＃34;

您需要填写连接数据和数据库名称。它输出匹配节点的数组，但你可以将输出格式化为你喜欢的任何东西（我推荐csv）。

<?php


//Set Parameters here
$env = "dev"; // Options [dev|prod] - Defaults to dev

$prodConnection = array(
                        "host" => "",
                        "user" => "",
                        "pass" => ""
                        );


$devConnection = array(
                        "host" => "",
                        "user" => "",
                        "pass" => ""
                        );

//Use the selected env settings
if($env == "prod"){
  $connection = $prodConnection;
} else {
  $connection = $devConnection;
}



function getTables($con, $database){
  //Get the set of field tables
  $sql = "SHOW TABLES FROM $database";
  $result = mysqli_query($con, $sql);

      echo "DB Error, could not list tables\n";
      echo 'MySQL Error: ' . mysql_error();
      exit;

      $tables[] = $row[0];

  $fieldTables[] = "field_data_body";
  $fieldTables[] = "field_data_comment_body";

  return $fieldTables;

  //echo $table . "\n";
  if( stripos($table, "field_data_field") !== FALSE){
    return TRUE;
  }

  var_dump($dataArray);
